De Oerhaal is a small, quiet marina situated on the Rjochte Grou, a through-waterway connecting to the Pikmeer, in the heart of Friesland.

The harbour offers around 25 berths ranging from 7 to 15 metres, available on a seasonal or annual basis, with electricity and water hookups at each berth along with shared toilet facilities.

From this access point, boaters can head directly out onto the Pikmeer or the broader Friese Meren, or navigate through to the city of Leeuwarden. The marina looks out across the Pikmeer toward the village of Grou, which lies roughly a 15-minute walk away.

During summer, a ferry service called Bram can shuttle visitors to the village or to waterside restaurants along the shore.
