Group programmes in the Fortress Triangle

One day, three rivers, six partners. Build it yourself.

Loevestein Castle, Fort Vuren, Gorinchem, Zaltbommel and the Biesbosch Line, connected by the Riveer ferries. Pick your profile, pick a building block per part of the day and we turn it into one programme, one schedule and one quote.

What kind of day are you here for?

Every destination takes on a different colour depending on what your team needs. Choose the profile that fits best; the rest of the site adapts.

Teambuilding

Active, together, with a story

Storm a fort, escape from a state prison, sail where three rivers meet. Here your team does things it has never done together.

Unwind & inspire

Calm, water and good conversations

A day to thank your team or treat a client. Slowly across the water, long at the table, with a story around every bend.

Meetings & content

Work in a place people remember

An away day, strategy session or client meeting with a meeting room in a castle, a fort or a fortress town. And between sessions: out on the water.

How it works

1

Choose your profile

Teambuilding, unwinding or meetings. We filter the building blocks and suggest an example day.

2

Fill morning, afternoon and evening

Per part of the day you pick one destination or activity. The planner includes Riveer crossing times so the day adds up.

3

Receive one proposal

Your request lands with one contact person of the working group, who aligns with all partners and sends one quote.

Six places, one story

Defending with water: that is the story that connects every location. UNESCO World Heritage, 600 years of history and three provinces, within half an hour’s sailing of each other.

The day planner

Put your day together. Morning at Loevestein, ferry to Gorinchem, into the windmill and a breakout session in the old centre? The planner shows when you are where, and what you need.

Offer for river cruise ships

Cruise lines and cruise directors find ready-made shore excursions of three or five hours from the quays of Gorinchem and Zaltbommel. In Dutch, English and German.
