Team retreats and team-building activities at Lake Dümmer.

Your next team sprint. At Lake Dümmer.
Everyday office life doesn’t bring people together. This does. The Marissa Resort provides the perfect setting for team retreats that leave a lasting impression—with authentic experiences, shared meals, lake views, and a program tailored to your team. Not the other way around.
Plan an offsite

Why an offsite works better here than elsewhere.

A great team retreat needs three things: a place that inspires, an activity program that brings people together, and enough time to just relax. The Marissa Resort offers all three.

Get away from the daily grind

18 hectares right on Lake Dümmer. No hotel lobby, no conference center. Just nature, water, and open space—enough of it all to truly unwind.

Flexible Meeting Setup

The spaces adapt to your work style—not the other way around. Whether you work at desks, sit in a circle, or simply fill up the Movingboard until there’s no more room.

From the dining table and living area, you have a great view of the lake and the surrounding nature

Living together

Apartments for one person and vacation homes for 4 to 10 people right in the resort. Cook together, relax together on the terrace—hot tub included. That brings people closer together more than any workshop ever could.

Ideas that aren't a program

From a puzzle walk by the lake to the climbing course at LYKKE LAND—Marissa Resort offers activities that truly bring teams together. No mandatory activities, no scripted activities. Just pick what suits you, book it, and get started.

Outdoor Escape Game

“Cornelius Blackwood and the Deadly Secret” – your team gets a tablet, a mysterious case, and off you go. This puzzle walk takes you to the most beautiful spots around Lake Dümmer. Think together, solve together, and stop the Phantom Society together. Starting at €15 per person.

Indoor Escape Game

For those who prefer to stay indoors—or when the weather doesn't cooperate. The indoor escape room immerses you in a richly detailed world full of secrets. Communication, creativity, and a little bit of chaos: just the thing for small teams looking to get to know each other better.

LYKKE LAND

Climbing course, parkour arena, low ropes course, Clip 'n' Climb – LYKKE LAND offers team-building without a facilitator. Just jump right in, cheer each other on, and see who finishes the course first. Works in any weather.

Bike ride

Rent bikes and explore Dümmer Nature Park. The trails around the lake are clearly marked—whether you’re taking a short loop or a long tour. Perfect for teams who just want to walk side by side instead of sitting across from each other.

Eat together. Grow together.

The best conversations don't happen during meetings. They happen afterward—over a meal, over a beer, on the terrace. The Marissa Resort offers the perfect settings for this.

Mezzomar: An Italian restaurant right on the plaza. The perfect spot for relaxed team evenings with great food and a view of the lake.
Beachmar: Mediterranean tapas and grilled specialties right on the beach. Sundowners included. Open April through October.
Skål Pub: For an evening with no agenda. Drinks, good company, and no more formalities.
Plan a team retreat

Work together. Live together.

Groups that stay together overnight work together differently. The vacation homes at Marissa Resort offer a true sense of community—multiple bedrooms, a spacious living area, and a private terrace with a Weber grill. Some even come with a hot tub and sauna included. For those who prefer a bit more privacy: apartments are right next door.

Apartments

For smaller groups and couples. The apartments at Marissa Resort offer comfort and privacy—with a private kitchen, balcony, and Scandinavian design by HAY. Ideal for teams staying together in small groups, while each unit retains its own unique character.

Houses

For teams that really want to come together. The vacation homes can accommodate up to 10 people—with multiple bedrooms, a spacious living area, a fully equipped kitchen, and a private terrace with a Weber grill. Some homes even include a hot tub and sauna. Not a hotel room, but a real home away from home.
