For our money, this is the best place to stay in Loyangalani, just a few hundred metres north of the village and with slight lake views. There's a range of decent bandas with arty wooden beds and attached bathrooms, or there are thatched huts based on a traditional Turkana design. The bar-restaurant area is a good place to hang out.
Steve, the owner, can help with organising boats, 4WDs and general onward transport.
