At the Laguna Baconao, 2km northeast of Los Corales, you'll find a restaurant, rowboats for hire and several short lakeside hikes, plus a folorn-looking zoo with crocodiles and the like. The lake supposedly contains five resident 'wild' dolphins. Various trails ply the lakeshore including one that circumnavigates it completely (8km). As it's a flora and fauna reserve you must first hire a guide for CUC$2. Multilingual Norge Ramos Barroso is your main man. Horse-riding is also available for CUC$10.
A road from the hamlet of Baconao follows the lake's north shore to the decent Restaurante Casa Rolando decorated bizarrely with native totems.
From Playa Baconao at the eastern corner of the lake, the paved road continues 3.5km up beautiful Valle de Río Baconao before turning into a dirt track. Soldiers at a checkpoint at the village turn back people trying to use the direct coastal road to Guantánamo because it passes alongside the US Naval Base. To continue east, you must backtrack 50km to Santiago de Cuba and take the inland road.
