The campsite at the park's reception centre is currently the only option at Uwinka. There are several choice spots, many with impressive views overlooking the forest and one on a wooden platform under a shelter that’s a godsend in the likely event of rain. The ablution block is cleaner than average, though showers (and toilets) come in buckets.
There are no kitchen facilities, but there's a small cafeteria serving up drinks and simple meals (RFr3000), so you don't really need to bring your own supplies. Tents (RFr10,000) can be hired and the staff can usually rustle up an extremely thin sleeping mat and sleeping bag for those who haven’t brought their own. It's a convenient base for those who don't have a vehicle, as most nature walks as well as the Canopy Walkway begin here.
