Although Flores [1]’s location by the lake would make water sports a logical recreational option, most recreation is outside of town or curiously lacks the water-borne focus you would expect to find.
Still, you can rent kayaks and mountain bikes at La Villa del Chef (tel. 7926-0296, 8 a.m.–11 p.m. Mon.–Sun., 1 p.m.–11 p.m. Tues.–Sun.) for $7 a day.
The other main recreational option involves lake tours offered by various boatmen congregating at the embarcaderos opposite Hotel Santana and on Playa Sur. Direct colectivo boats ($0.50) can take you across the lake to the town of San Miguel and leave from a dock next to Posada de Don José. The lake tours can be had for $15–20 and include a trip to the lakeshore opposite the island’s northwest corner to Petencito Zoo [2], the Mayan ruins of Tayazal [3], and ARCAS [4], a wildlife rescue center.
Flores’s many outfitters [5] can hook you up with one- or multiday adventures to Petén’s increasingly popular parks and archaeological sites.
