Natuurkampeerterrein Lettelbert sits on the Lettelberterdiep in the peat-meadow landscape of Lettelbert, on the northern edge of the Leekstermeer, in the border region of Groningen, Friesland, and Drenthe.

It is a small, quiet nature campsite managed by volunteers of the NIVON organization, with around 30 spacious pitches spread across several fields. The grounds are sheltered by hedgerows that provide shade and windbreak, while sunny spots are also available.

A valid nature-camping card or NIVON membership is required to stay here. A landing stage at the site's entrance gives direct access to the Leekstermeer, where canoeing, sailing, and surfing are possible.

Within walking distance lies the Lettelberterplas, a sand-extraction lake with a children's swimming beach.

The surrounding coulisse landscape of the Westerkwartier is well suited to cycling and hiking, and the nature reserve De Onlanden borders the Lettelberterdiep nearby. The city of Groningen is roughly 10 km away and reachable by bike.
