Jachthaven Biesbosch is a large inland marina located at Nieuwe Jachthaven 20 in Drimmelen, situated on the edge of the Biesbosch National Park — one of the largest freshwater wetlands in Europe.

Once a historic fishing port, the marina has grown into the largest inland marina in Europe, with over 1,400 pontoon berths. It serves as a prime access point for exploring the national park's extensive network of rivers, lakes, and waterways by boat.

The marina is well connected by road via the A16, A27, and A59 motorways, and is reachable by rail with Breda Station roughly 20 minutes away by taxi. VHF Channel 31 is available for on-water navigation assistance.
