Tropical Islands Resort is one of the strangest places within day-trip range of Berlin. The 60,000-square-meter indoor “tropical beach” sits inside the former Aerium hangar of CargoLifter — the failed German airship company that built one of the largest free-standing buildings in the world in the late 1990s and went bankrupt in 2002 before ever filling it with airships. The Malaysian company Tanjong took over the empty hangar in 2003, filled it with 24°C tropical air, a rainforest, a Bali-style village, and a 200-meter beach, and reopened it as a year-round tropical resort. Eight kilometers across, with the world’s largest indoor tropical sea, it’s an architectural and tourism oddity that genuinely has no equivalent anywhere else in Europe.
This guide covers everything Berlin visitors need to know about a Tropical Islands day trip in 2026 — how to get there, what’s worth your time inside the building, what’s a tourist trap, the realistic value proposition, and the cases where it makes sense versus the cases where it doesn’t.

What Is Tropical Islands?
Tropical Islands is an indoor water park, tropical rainforest, beach resort, and overnight accommodation, all contained within a single enormous hangar. The space holds 50,000 plants, a 200-meter sand beach, an artificial lagoon, three pools (the tropical sea, the Bali Lagoon, and the kids’ pool), water slides, a “Tropino” kids’ area, restaurants from a half-dozen cuisines, and overnight tents and cabins for visitors who want to extend the experience. The temperature is held at a constant 26°C; the humidity matches what you’d expect in a tropical climate. Standing inside on a -5°C January day in Brandenburg is genuinely disorienting.
The complex also includes a separate Amazonia outdoor area (open seasonally May-October) with additional pools, slides, and beach space — and the Sauna Village, a Finnish/German-style sauna complex with 9 different saunas adjacent to the main hangar. The Sauna Village requires a separate ticket and is adults-only.
Why the Building Itself Is Worth Seeing
The Aerium hangar is one of the largest free-standing buildings in the world. The interior volume of 5.5 million cubic meters could fit the Statue of Liberty standing upright. The dimensions — 360 meters long, 210 meters wide, 107 meters high — were designed to house multiple CargoLifter CL160 airships, each of which was planned to be over 250 meters long. The company’s bankruptcy in 2002 left the building completed but empty, and the German federal government held responsibility for it through the early 2000s.
The conversion to Tropical Islands was an engineering challenge in its own right. The interior climate is maintained by a network of heating, humidification, and air-handling systems built specifically for the project. The roof of the hangar is partially transparent, allowing natural sunlight in during the day. The rainforest section was planted in 2003-2004 and has matured into a genuine indoor forest.
The CargoLifter Story — Why the Building Exists
The reason Tropical Islands exists in this specific location is one of the strangest German business stories of the past thirty years. In 1996, a group of German engineers founded CargoLifter AG with a plan to build heavy-lift airships capable of moving 160-ton industrial cargo loads (factory turbines, generators, oversize construction equipment) to remote locations without roads. The company raised about €350 million from private investors and a regional government grant from Brandenburg, partly built around the promise of bringing high-tech industrial jobs to a struggling area south of Berlin.
The Aerium hangar at Krausnick was constructed between 1998 and 2000 specifically to house multiple CL160 airships under construction simultaneously. The building was completed before any airships were ever built. By 2002, the company had run out of money and entered insolvency without ever flying a working CL160. The Brandenburg government was left holding an enormous empty hangar that no obvious industrial use could fill. Several proposals — wind turbine assembly, military training facility, exhibition space — were considered before the Malaysian Tanjong Group offered to buy the hangar and convert it to a tropical resort. The conversion cost approximately €100 million; the resort opened in December 2004.
The story is part of the experience. The visitor information boards near the resort entrance cover the CargoLifter history, and you can see hints of the original industrial design in the hangar structure — the massive doors at each end, the building’s structural geometry, the airship-scaled volumes that now contain a tropical sea.
How to Get to Tropical Islands
The most reliable route is the RE2 regional train from Berlin to “Brand Tropical Islands” station. The journey takes about 90 minutes from Berlin Hauptbahnhof. Trains run roughly hourly throughout the day. From the station, a free shuttle bus runs to the resort entrance every 30 minutes; the ride takes about 5 minutes. The Brandenburg-Ticket (€33 base, +€8 per additional traveler) is the most economical option for groups of 2-5.
For drivers, Tropical Islands is about 60-70 minutes south of Berlin on the A13. Parking on-site costs €5 per day. The drive is the faster option for families with multiple kids and significant luggage (towels, swimwear, snacks).
Tickets and Pricing
Ticket pricing varies by day type (weekday vs weekend), season, and how far in advance you book. The standard structure:
Day Pass (Adult): €54 standard, around €44-49 for advance online bookings. Children 6-14: €34-44. Kids 5 and under: free with adult.
Family Day Tickets: Family of 4 around €135-160 depending on age and day. Family of 5+ slightly more.
Twilight Tickets (after 4 pm): €34-40 for adults. Better value if you only want a few hours.
Sauna Village separate ticket: €15 add-on for adults (16+ only). Includes textile-free German sauna culture; not suitable for visitors uncomfortable with the convention.
Buy tickets online through the official tropical-islands.de site — there’s no significant advantage to buying at the door, and you’ll skip the entry queue. The ticket grants 8 hours of access; overnight visitors stay in the cabin/tent accommodations on-site.
What’s Worth Your Time Inside
The Beach and Tropical Sea
The 200-meter beach and the surrounding “Tropical Sea” — about 1.4 million liters of water — are the central attraction. The sand is genuine quartz sand, not sticky synthetic. The water temperature is held at 28°C. The pool is shallow at the beach edge and deepens to 1.5-2 meters. Lifeguards present. Spend 1-2 hours here for the headline experience.
The Rainforest Trail
The genuinely interesting part of Tropical Islands for adults who aren’t focused on the water park. The rainforest section contains over 50,000 plants from real tropical biomes — Indonesian, Thai, Polynesian, Malaysian, and Amazonian — with several free-flying tropical birds, fish in the streams, and small mammals in dedicated enclosures. Walking the rainforest trail takes about 45-60 minutes. The plants have matured significantly since 2003-2004; the forest has the feel of a real micro-environment now, not a recent plant installation.
The Water Slides and Towers
Tropical Islands has Europe’s tallest indoor water slide tower — the 27-meter slide tower with multiple slides of varying speeds and styles. The “Cobra” and “Black Hole” are the more thrilling options; gentler slides serve younger kids. The tower also has good views of the entire hangar interior. Wait times for the slides can be significant on weekends.
The Bali Lagoon and Themed Areas
The Bali Lagoon — a smaller themed pool with Balinese-style architecture, gentler water, and lounger access — is the more relaxed adult-focused area. The themed “villages” (replica Polynesian houses, Asian-style food courts) range from genuinely charming to lightly tourist-trap depending on your perspective. The Tropino kids’ play area has indoor playgrounds, soft-play structures, and supervised activities — solid for families with kids under 10.
Amazonia (Outdoor, Seasonal)
The outdoor Amazonia section, open May through October, adds additional outdoor pools, slides, and beach space. Worth the extra time on summer days when weather cooperates. Not separately ticketed for day pass holders.
When Tropical Islands Makes Sense (and When It Doesn’t)
Good for: winter visits when Berlin weather is brutal and you want a warm-weather break without flying anywhere; families with kids 5-12 who’ll enjoy the slides and the kids’ areas; rainy weekend bailout when other Berlin plans collapse; the architecturally curious who want to experience the inside of the converted CargoLifter hangar; group trips or birthdays that need a single all-day venue; visitors who want a sauna experience without committing to the broader German sauna culture.
Skip if: you have only a few days in Berlin and want to see the city itself; you’re a first-time Berlin visitor with a checklist of major attractions; you find theme-park environments grating; the price-per-experience ratio doesn’t work for you (a full family of 4 will spend €170+ before food and drinks); you prefer real tropical environments and feel the simulation is uncanny rather than delightful. Most Berlin first-time visitors should skip Tropical Islands and prioritize the city. It’s a “second visit” or “long trip” addition rather than a must-see.
Practical Tips
Bring your own towel. The on-site towel rental is €6 and the quality is fine but it’s an unnecessary cost. Bring water sandals or flip-flops for the wet floors. Most people change at the locker rooms by the entrance, but you can also rent a private cabana for the day (€50+) if you’re traveling with multiple kids or want a base of operations. Food and drinks are pricey — a meal for two with drinks runs €30-50. The on-site Asian and tropical-themed restaurants are quality-mediocre at tourist-trap prices; many visitors bring snacks (allowed in the seating areas).
The complex is open 24 hours — overnight stays in tents (€40-60) or cabins (€80-150+) are popular with European families on multi-day Berlin trips. The overnight option lets you experience the place at off-peak hours and avoid the long return-trip transit; many regulars say the night experience (the artificial dawn/dusk lighting, the quieter pools) is the version worth doing.

Combining With Other Berlin Plans
Tropical Islands works best as a stand-alone day. The transit takes too long to comfortably combine with other Berlin sightseeing. If you’re traveling with kids who’ll be exhausted from a Tropical Islands day, plan a light evening — pizza in the hotel district, an early night.

Frequently Asked Questions
Is Tropical Islands worth visiting from Berlin?
For families with kids who enjoy water parks: yes, especially in winter when outdoor activities are limited. For first-time Berlin adult visitors: probably not — your time is better spent in the city itself. As a second-visit or long-trip addition for visitors who’ve already seen the major Berlin sights: a fun curiosity.
How long is the train from Berlin?
The RE2 regional train takes about 90 minutes from Berlin Hauptbahnhof to “Brand Tropical Islands” station. Free shuttle bus from the station to the resort entrance. Trains run roughly hourly.
How much does a Tropical Islands day cost?
Adult day pass €54 standard, €44-49 advance online. Children €34-44. Family of 4 around €135-160. Plus train (Brandenburg-Ticket €33+ for groups). Plus food/drink €25-40 per person. Plus towel rental €6 if needed. Total day cost typically €70-90 per person, more for families with multiple kids.
Is it open year-round?
Yes, 24 hours, year-round. The indoor temperature is held at 26°C regardless of outside conditions. Winter visits (December-February) are particularly popular because the contrast is most extreme. Summer visits work too; the outdoor Amazonia section opens May-October.
Can I stay overnight?
Yes. Tents from €40-60, cabins from €80-150, hotel-style rooms at higher prices. Overnight stays let you experience the off-peak hours and avoid the long return-trip transit. Popular with European families on multi-day Berlin trips.
Is the Sauna Village clothing-optional?
Yes — German sauna culture is textile-free, and the Sauna Village follows that convention. Towels are used for sitting and modesty. Visitors uncomfortable with this convention should skip the Sauna Village; the main resort areas are fully clothed/swimsuit.
Should I do this on a Berlin first visit?
Probably not. First-time Berlin visitors have 4-7 days of major Berlin attractions to see — the museums, the historical sights, the cultural events, the food scene. Tropical Islands is a fun curiosity that works for return visitors or families specifically traveling for the kids. See our things to do in Berlin pillar for the priorities a first-time visitor should focus on.
Final Word
Tropical Islands is a place that defies easy recommendation. The building itself is one of the most distinctive structures in Europe. The interior environment is genuinely strange. The kids’ experience is solid. The economic value depends entirely on whether the simulation appeals to you — some visitors love the bizarre joy of swimming in a synthetic beach at 26°C while it’s freezing rain outside; others find the whole thing slightly uncanny. Visit it if the description has you curious. Skip it if your Berlin schedule is already full of more obviously rewarding things.
