Básar is the choice base for Icelanders, largely due to its beautiful position in the trees. There’s hut (mattress only) accommodation for 83 people. Camping space gets extremely crowded on summer weekends. There's a barbecue and good-sized kitchen with large communal wooden benches for eating. Phone charging costs 500kr, showers per person also 500kr.
Básar is at the end of the F249, but not accessible with regular 4WD due to the river crossings en route. Amphibious buses stop here. Booking is advisable in summer.
