Camping Maasterras operates its own paved boat ramp — the Botenhelling Camping Maasterras — giving campers direct water access to the Asseltse Plassen, part of the broader Maasplassen area covering some 3,000 hectares.

The ramp is available to campsite guests, and if a pitch has sufficient space, boats may be stored there at no extra charge.

The Asseltse Plassen offer good conditions for general watersports and fishing, though personal watercraft such as jet skis are not permitted on these waters.

The campsite itself sits in a quiet, natural setting near Swalmen, roughly five kilometres from the centre of Roermond.
