Jachthaven 't Eibertsnest, also known as Jachthaven Kuikhorne, is a well-maintained marina located in De Westereen in the heart of the Friese Wouden, in northeast Friesland.

Situated on the Nieuwe Vaart along the Lits-Lauwersmeerroute, it lies between two national parks: De Alde Feanen and Lauwersmeer. The marina has been operating since 1982 and offers around 300 open berths accommodating vessels up to 12 meters.

A trailer ramp on site provides water access directly onto the Nieuwe Vaart. Visiting boaters are welcome, with dedicated passanten berths available alongside the grass bank or at the main jetty.

Cycling routes through the Friese Wouden depart directly from the marina, with routes leading to Dokkum and Bergum. A village with shops is approximately two kilometers away.
