Best Outdoor Dining in Helsinki: Terraces, Rooftops, and Island Tables

50+ Terraces and 19 Hours of Daylight — Here Are the Ones Worth Your Time

In the 1930s, an architect drew a mooring point on the roof of a Helsinki hotel. The plan: passengers aboard the Graf Zeppelin airship would descend by ladder, cross the rooftop, and order a cocktail thirteen floors above the city.

The Zeppelin never came.

The cocktails did. Atelje Bar opened on that same roof in 1951 and hasn’t closed since. But the idea of drinking outside in Helsinki predates the airship fantasy by almost a century — in 1840, a confectioner named Johan Daniel Jerngren dragged a wooden kiosk into Esplanadi park and sold lemonade to anyone willing to sit outside long enough to finish one. That kiosk became Kappeli. Hampus Dalström designed the permanent building that opened June 4, 1867, and Sibelius, Gallen-Kallela, and Eino Leino drank there before they were names you’d recognise.

Helsinki now has over 50 outdoor restaurants, a rooftop bar on basically every hotel with more than eight floors, and nearly 19 hours of daylight in June. Terraces fill past midnight and nobody thinks that’s unusual.

So here’s the question no best-of list asks: with all those terraces and a sun that barely sets, why do locals keep ferrying twenty minutes across the Baltic to eat soup on a former ammunition dump?

We’ll get there. First, the conventional picks — because some of them genuinely earn their spot.

Kappeli still serves on the same Esplanadi spot — but Helsinki’s outdoor ambition has moved upward.

5 Rooftop Bars from Street Level to 100 Metres

Atelje Bar, Hotel Torni — the Zeppelin roof. Seventy metres up, thirteenth floor. The views haven’t changed since 1951. The toilet has a window more photographed than most Helsinki landmarks. No reservations, no real food menu — this is a drinks-only destination (€€). Go on a weekday afternoon. Weekends get shoulder-to-shoulder by 7pm and the queue starts at the elevator.

BISOUBISOU is the newest arrival — opened April 30, 2025, sitting at 100 metres in the REDI tower in Kalasatama. French-New York energy, a 60-seat glass veranda that works year-round, and views over East Helsinki and the archipelago that most locals haven’t seen because they still think Kalasatama is just a construction site. It isn’t anymore. Check bisoubisou.fi for reservations (€€€).

Skyroom at Clarion Hotel is the 16th-floor play: floor-to-ceiling windows, the western harbour stretched out below, a DJ on Friday and Saturday evenings. Good for a drink. Less good for a quiet dinner.

10. Kerros at Sokos Hotel Vaakuna has had 360-degree views next to Helsinki Central Station since 1947. Reliable. Predictable. Your parents went there.

Rooftop Miami on top of Stockmann opens late April and runs through September — all outdoor, panoramic over Esplanadi. Crowded, loud, fun if that’s what you’re after.

Honest assessment: rooftop bars in Helsinki are reliable but rarely surprising. The altitude does the heavy lifting. The drinks are fine. The food is afterthought-adjacent. If you want atmosphere that comes from the place itself rather than the height, keep reading.

The Terraces That Were Here First

Kappeli — Jerngren’s 1840 kiosk, grown up. Still the most popular summer terrace in Helsinki, still on the same Esplanadi spot. Not the best terrace — the most loved terrace. Live music on the bandstand, a beer that costs more than it should, and the kind of place where you start the evening before deciding where to end it. (€€)

Restaurant Savoy, 8th floor overlooking Esplanadi, is the terrace Helsinki books when it wants to impress. Alvar Aalto designed the interior. Ilse Crawford redesigned it. Bees on the rooftop make honey for the kitchen. At 8pm on a July evening, the Esplanadi linden trees are at eye level and the light does something you’ll try to photograph and fail. Book at ravintolasavoy.fi — July terrace tables fill two weeks ahead. (€€€€)

Sea Horse (est. 1933) opens its terrace on Vappu Eve, April 30 — rain or shine, every year, no exceptions. This tradition has marked the start of Helsinki’s terrace season for decades. Fried Baltic herring, vorschmack, salmon soup. This is where Helsinki eats without performing. (€€)

Waterfront Terraces Where the Baltic Does the Work

Löyly is the one everyone names, and it earns it — a public sauna and restaurant complex in Hernesaari with over 1,600 square metres of terrace arranged like bleachers at a sea-level concert where the Baltic is the performer. Three levels: main terrace, roof terrace, lookout terrace. Time Magazine put it on their 100 Greatest Places list. The food is fine. You’re not here for the food. You’re here because someone stacked three terraces facing the open Baltic and the architecture makes you feel like you’re sitting inside a sculpture. Come for the terrace, stay for the sauna. Year-round operation, which matters in a city where most terraces are seasonal. Book the restaurant side at loylyhelsinki.fi (€€–€€€) — weekend dinner slots fill by Thursday, so book early or come on a weekday. Walk-ins work for the terrace bar.

Mattolaituri in Kaivopuisto is the opposite energy: beach chairs, sea views, the vibe of someone’s well-organised garden party. The name means “carpet pier” — this is where Helsinki residents used to wash their rugs in the sea.

Now they drink rosé. Progress.

Allas Sea Pool at Market Square harbour has three dining concepts stacked together. The location is unbeatable. The execution is less so. Tourist-heavy. Worth a drink at the Sky Bar for the harbour view, but don’t plan your evening around it.

Why the Best Table in Helsinki Requires a Ferry

Every terrace list in Helsinki covers the same ground: rooftop bars, Esplanadi terraces, maybe Löyly. None of them require a boat.

Helsinki has an archipelago problem — meaning it has dozens of islands within twenty minutes of the city centre, and several have restaurants worth the crossing. The water works like a velvet rope that nobody resents. The ferry schedule creates commitment. And the islands themselves do something no rooftop can: they surround you.

Särkänlinna sits on Särkänsaari, a fortress island dating to 1748. The restaurant has operated since 1924 and has hosted crayfish parties for over a hundred years. You reach it by shuttle boat from Kaivopuisto Park — check ravintolasarkanlinna.fi for shuttle times and the current menu. If you’ve never eaten crayfish on a Baltic fortress while the sun refuses to set, the season opens July 22. Book early — crayfish nights sell out. (€€€)

Restaurant NJK occupies a white villa on Valkosaari designed by Estlander and Zettergren, inaugurated August 31, 1900. The yacht club NJK moved to the island in 1885. It still feels like arriving at someone’s very elegant summer house by boat — someone who doesn’t need you to know how much the house cost. Dinner reservations at ravintolanjk.fi (€€€) — crayfish season books out fast, so reserve in June if you want a July seat.

Restaurant Lonna on Lonna island — 60 seats, seasonal organic Finnish produce, and an island small enough that walk-ins aren’t an option. Reserve or don’t go. JT-Line ferry from Kauppatori. Open May through September. (€€–€€€)

Suomenlinna has Bastion Bistro (former infantry barracks, terraced garden with Helsinki skyline views) and Restaurant Adlerfelt (250-year-old building, seasonal menus). Most tourists already know about these — a million visitors a year will do that. The island restaurants above are the ones the lists miss.

And then there’s the one that shouldn’t exist at all. An island sealed from civilians for over 200 years — used first by the Russian navy, then by the Finnish military — that now has a wine bar, a DJ, and a sommelier. The full story of how an ammunition island became Helsinki’s only island wine bar is worth reading. But here’s the short version.

How Oliver Laiho Turned an Ammunition Dump into Helsinki’s Only Island Wine Bar

Vallisaari spent its entire modern history telling people to stay away. The Russian navy stored ammunition there. The Finnish Defence Forces kept it after independence. For over 200 years, no ordinary person set foot on the island.

Then, in May 2016, it opened to the public for the first time.

Here’s what two centuries of enforced absence does to 110 hectares of Baltic island: over 400 vascular plant species colonised the land without a single human decision — more than any other surveyed island in the Helsinki metropolitan archipelago. Over 1,000 butterfly and moth species, more than 100 on Finland’s endangered red list. Six protected bat species. The military kept everyone out, and nature treated the whole island like a laboratory with a two-hundred-year grant and no oversight committee.

Oliver Laiho looked at that and saw a wine bar.

Not a nature centre. Not a museum. A place where a sommelier goes table to table telling the producer’s story, a DJ plays between pours, and a south-facing terrace opens onto direct views of the Suomenlinna UNESCO fortress across the water. He built IISI specifically because he found traditional wine tastings “too quiet and too far from the real reason people drink wine: conversation.” If you want to see what a DJ set on an ammunition island actually looks like: @iisivallisaari on Instagram.

IISI Bistro now holds a 4.7/5 Google rating from 163 reviews. The salmon soup gets mentioned in almost every one of them. Cafe IISI runs 4.7/5 from 268 reviews. Wine tastings happen Fridays and Saturdays at 1pm — about 2 hours, five wines by rotating theme, tapas buffet included, and a DJ who apparently doesn’t find it strange to play music on a former ammunition depot to people swirling Sicilian whites.

Hours worth knowing: IISI Bistro is open daily (Mon-Tue 11-19, Wed-Thu 12-20, Fri-Sat 11-21, Sun 11-19). Cafe IISI runs Thursday through Sunday only (Thu 10-20, Fri-Sat 10-21, Sun 12-17). Don’t ferry over on a Wednesday expecting the cafe — it’s closed Mon-Wed. The bistro will feed you, but the cafe won’t.

The honest caveat: this is not a quick lunch spot. The ferry takes twenty minutes each way, and the schedule means you’re committing to a half-day minimum. Don’t go if you’re in a rush. Go if you want to eat salmon soup on a nature reserve that exists because the military accidentally preserved it, drink wine chosen by someone who cares about it more than you do, and walk back to the ferry through forest that has never been landscaped.

No rooftop in Helsinki does that. No rooftop anywhere does.

Book your seat for a Vallisaari wine tasting at iisivallisaari.fi/tapahtumat. For groups of 20+, email oliver@iisivallisaari.fi or call +358 40 027 8849.

Wine tasting prices range from EUR 59 to 79 per person depending on the theme. The Bacchanalia Wine & Music Festival runs July 17–18 (15 EUR advance, 20 EUR at the gate, wine tokens 4 EUR for 8cl). Book ahead — the island has capacity limits and the popular dates fill.

Terrace Season 2026: Every Date, Ferry, and Price You Need

When it starts: Vappu Eve (April 30) kicks off terrace season. Most city terraces follow within a week. Island restaurants depend on ferry schedules and open later.

Island access:

• JT-Line ferry to Vallisaari: May 20 to September 12, 2026. Adults 9.80 EUR return, children 7–17: 6.80 EUR, seniors/students: 6.80 EUR. Under 7 free. Departs Kauppatori (Market Square), approximately 20 minutes each way.
• Särkänlinna shuttle: seasonal, from Kaivopuisto Park.
• Lonna, NJK, Suomenlinna: JT-Line or HSL ferry from Kauppatori.

Peak season: June through August. Average 17–20 degrees during the day, 12–14 in the evening. Layers are not optional on sea-facing terraces — the wind off the Baltic makes it feel five degrees colder than whatever your phone says.

What if it rains? August is statistically Helsinki’s wettest month. Löyly operates year-round with covered areas. Most hotel rooftop bars (BISOUBISOU, Skyroom, 10. Kerros) have indoor seating or glass verandas. On Vallisaari, IISI Bistro seats 80 and has indoor space — wine tastings run rain or shine. If the forecast looks bad for an island day, have a backup city terrace with a roof. Or bring a jacket that actually works and lean into it. This is Finland.

Language: Helsinki restaurant staff speak English. Menus at all venues listed here are available in English. IISI wine tastings are conducted in Finnish and English.

White Nights: Helsinki gets nearly 19 hours of daylight in June. Terraces fill past midnight from mid-May to early August. Summer solstice 2026 is June 21. If you’ve never experienced 11pm daylight with a glass of wine on an island — that’s twenty minutes from Market Square and costs less than your last airport cocktail.

What to book now:

• IISI Bistro menu, hours, and ferry connections — season opens June 6
• IISI season closing party: September 12 (Vallisaari Shutdown)
• Särkänlinna crayfish season: opens July 22
• Restaurant Lonna: reservations essential — 60 seats, no walk-ins
• Restaurant Savoy: ravintolasavoy.fi — book well ahead for terrace

Dress code: Helsinki is casual. Smart casual works everywhere, including restaurants with tasting menus. The only real rule: bring an actual jacket for any terrace near water. Not a fashion layer. A jacket that does something when the wind picks up.

You could book Savoy and be perfectly happy. You could spend a Saturday evening at Löyly and call it the best terrace in Helsinki. Most people do.

But somewhere in Helsinki right now, someone is checking the JT-Line timetable. They’ll text a friend. They’ll pack a jacket — a real one, not a fashion layer. Twenty minutes from now, the city will be behind them, the fortress will be across the water, and the salmon soup will be on its way. It’s been like this since 2016. For two hundred years before that, nobody was allowed to know what they were missing.

The standouts by category: Island dining — IISI Bistro on Vallisaari (ferry from Kauppatori, 20 min, 9.80 EUR return, open May 20 to Sep 12) and Särkänlinna on Särkänsaari (fortress island, 100+ years of crayfish parties). Rooftop — Atelje Bar at Hotel Torni (13th floor, since 1951), BISOUBISOU at REDI (100m, year-round glass veranda), Skyroom at Clarion (16th floor, DJ weekends). Waterfront — Löyly in Hernesaari (1,600m2 terrace, Time Magazine 100 Greatest Places), Mattolaituri in Kaivopuisto (beach chairs, sea views). Historic — Kappeli on Esplanadi (est. 1840), Restaurant Savoy (8th floor, Aalto-designed, Esplanadi views), Sea Horse (est. 1933, opens Vappu Eve). Accessibility note: island venues require ferry boarding — wheelchair accessibility varies by vessel, so check with JT-Line or HSL before travelling.

When do Helsinki terraces open for the season?

Most Helsinki terraces open around Vappu (April 30 to May 1). Sea Horse opens on May Day Eve every year, rain or shine — a tradition spanning decades. Rooftop Miami at Stockmann opens late April. Island restaurants open later with ferry schedules: IISI Vallisaari opens when JT-Line service begins (May 20, 2026). Peak season runs June through August. Most island venues close by mid-September. Year-round options include Löyly and several hotel rooftop bars. For context on what Vappu means to Helsinki: during Vappu 2019, an estimated 21,000 bottles of sparkling wine were consumed in Kaivopuisto park alone. That’s when you know the season has started.

What outdoor restaurants in Helsinki have the best views?

Sea views from water level: Löyly (Hernesaari, Baltic panorama, 1,600m2 terrace), Allas Sea Pool terrace (Market Square harbour), Mattolaituri (Kaivopuisto, sea and beach chairs). Sea views from height: Skyroom at Clarion (16th floor, western harbour), Atelje Bar at Hotel Torni (13th floor, 70m, city panorama), BISOUBISOU at REDI (100m, East Helsinki and archipelago). Historic terrace: Restaurant Savoy (8th floor, Esplanadi, Aalto-designed). Island dining surrounded by water: IISI Bistro on Vallisaari (south-facing, Suomenlinna UNESCO fortress views), Särkänlinna on Särkänsaari (open sea and Kaivopuisto), Restaurant NJK on Valkosaari (1900 villa, harbour views). Photographer’s note: west-facing terraces (Löyly, Skyroom) get the best light from 9–10pm in June — golden hour lasts over an hour when the sun barely sets.

Is Vallisaari worth visiting just for food and dining?

Yes, if you have the time. IISI Bistro holds a 4.7/5 Google rating (163 reviews), with the salmon soup mentioned in nearly every review. The ferry costs 9.80 EUR return and runs May 20 to September 12. Budget 3-4 hours minimum: 20-minute ferry, walk through the island’s 400+ plant species and historic military ruins, eat at the bistro or cafe, return. Wine tastings run Fridays and Saturdays at 1pm — about 2 hours, five wines, sommelier and DJ, tapas buffet included, 59-79 EUR per person. Not suitable for a quick lunch. The ferry schedule means you’re committing to a half-day. That’s the point. For families: the island’s nature trails and military ruins are excellent for kids — the wine tastings are adults-only.

How long is Helsinki’s outdoor dining season?

Approximately 4 to 5 months. Shoulder season starts late April (Vappu Eve, April 30). Peak runs June through August — average temperatures of 17-20 degrees and nearly 19 hours of daylight, with terraces filling past midnight during the White Nights (mid-May to early August). Island restaurants close earlier: IISI Vallisaari closes September 12, 2026. Most city terraces wind down by end of September. Year-round terraces include Löyly and some hotel rooftops with heating. Insider tip: September is underrated — fewer tourists, terraces still open, and some restaurants run end-of-season menus at lower prices before closing for winter.
