Tumichucuá is a small community about 25km south of town (B$30 by moto-taxi) toward ‘El Triángulo’ (the road junction to Cobija). There is a lake for swimming and a forested island with walking trails, plus cabins. Nobody is sure how far from Riberalta it is, as according to local legend the lake moves at night, sometimes coming to rest closer to the town, sometimes further away.
