Trintelhaven is an access point on the IJsselmeer, situated along the Markerwaarddijk (also known as the Houtribdijk) roughly midway between Lelystad and Enkhuizen in the province of Flevoland.

The site sits on a working harbor and offers a broad, open stretch of water with good fetch for prevailing winds, making it a notable launch point for water-sports enthusiasts. Parking is available on site.

The spot has become a recognized destination for kitesurfing, wingfoil, and windfoil, with conditions that can turn choppy in stronger winds — best suited to intermediate and above riders.

As of April 2025, kitesurfing is officially permitted here from April through July. The sandy beach is freely accessible, and the open water also serves paddlers and boaters. Mariners use "Trintelhaven" as a reference weather station for IJsselmeer forecasts.
