Who it’s for

Unwind & inspire

Calm, water and good conversations

Sometimes the goal of a day is simply that everyone goes home recharged. The Fortress Triangle does that with water, wind and time: a guided boat trip through the Biesbosch, a tasting in a working windmill, a long lunch on the ramparts of Zaltbommel. No programme to rush through, but a day you talk about for weeks.
