Jachthaven Midwolda is a marina situated at the northern tip of the Oldambtmeer, in the eastern part of the province of Groningen. It has been in operation since 2007, the same year the lake opened for water sports and recreation.

The marina offers more than 200 moorings, with berths available for boats ranging from 4 to 13 meters in length. As an access point to the Oldambtmeer, the marina serves as a practical base for exploring the lake by water.

Boaters should note that the lake is shallow, with an average depth of around 1. 30 meters, and vessels should have a draught of no more than 1. 10 meters.

Those arriving by boat can reach the lake via Winschoterdiep or Termunterzijldiep, though the access routes are limited in height and width. A large parking area is located directly beside the marina for those arriving by car.
