Elfhoeven is a nature and recreation area situated directly alongside Plas Elfhoeven, one of the 13 Reeuwijkse Plassen lakes in South Holland. The area is accessible via the Korssendijk and Groene Ree and can be explored on foot or by bicycle.

A long wooden pier extends over the lake, where boats frequently moor during summer months, making it a convenient stop for those arriving by rowboat or canoe. Visitors can rest on benches overlooking the water or take a swim after a walk.

The site is also noted as a pleasant spot for paddleboarding. The Goudse Watersportvereniging Elfhoeven, an active sailing and rowing club, operates nearby and offers moorings, shore storage, and sailing instruction.
