Lân & Mar is a small, quiet waterfront campground in Heeg, Friesland, situated directly on the Hegemer Mar. The meadow terrain is bordered by hedges and features a natural shoreline, giving the site a rural, unhurried character.

Touring pitches range from roughly 100 to 145 m², and a handful of rental accommodations and permanent pitches round out the roughly 2-hectare property. The campground is well suited to water-sports enthusiasts.

A small marina offers moorings, a boat slip, trailer ramp, shore power, and a water point, with direct access onto the lake. Boat rental is available on site. Additional amenities include a children's playground, beach volleyball, and washing facilities.

The village center of Heeg, with restaurants and shops, lies about 1 km away. The season generally runs from late March or early April through mid-October.
