For a floral appreciation of Bayamo's evergreen hinterland, head to this botanic garden about 16km outside the city off the Guisa road. It's on very few itineraries, so you can have the serene, serendipitous 104 hectares more or less to yourself. There are 74 types of palms, scores of cacti, blooming orchids and sections for endangered and medicinal plants.
The guided tour (Spanish only) gains you access to greenhouses, notable for the showy ornamentals. To get here, take the road to Santiago de Cuba for 6km and turn left at the signposted junction for Guisa. After 10km you'll see the botanic garden sign on the right. Trucks in this direction leave from the intermunicipal bus station in front of the train station.
