The Snitser Mar, officially known in Dutch as the Sneekermeer, is a lake in the Dutch province of Friesland, situated between the city of Sneek and the villages of Terhorne (Terherne) and Goingarijp. It is one of the largest and most significant of the 24 Frisian Lakes that make up the broader lake district of Central and Southwest Friesland, a region known locally as the Zuidwesthoek (Súdwesthoeke).

The lake is well known for its popularity among water sports enthusiasts and draws boaters from across the Netherlands, particularly during the summer months. The peak of the boating season coincides with the Sneekweek (Snitswike), an annual boating event centered on Sneek, which means paddlers should expect significantly increased vessel traffic on the water during this period.

A notable feature of the Snitser Mar is Start Island, located in the heart of the lake. The island hosts a restaurant and a playground, and can only be reached by ferry or private watercraft, making it a practical destination for paddlers crossing the lake. Several marinas around the island offer mooring facilities.

The lake sits within the municipality of Súdwest-Fryslân and forms part of the broader Frisian Lakes region, which is a major recreational boating area. Given the lake's prominence and the volume of motorized boat traffic it attracts — especially in summer — paddlers should be aware that conditions can be choppy and that sharing the water with larger vessels is a routine part of the experience here. The surrounding area offers connections to other Frisian lakes and waterways, making the Snitser Mar a potential hub for multi-day paddling routes through the wider lake network.
