Buses depart about every 25 minutes (but don’t bank on it) from next to the Centro de Convenciones (near the back of the market) or from the ferry dock, and head along Av Rueda Medina, stopping along the way. You can get to Hacienda Mundaca, within 300m of the Turtle farm, and as far south as Playa Lancheros (1.5km north of Playa Garrafón). Get taxis from the stand or flag one down. Taxi rates are set by the municipal government and posted at the taxi stand just south of the passenger ferry dock. As always, agree on a price before getting in.
Cycling is a great way to get around the island. A number of shops rent bikes for about M$20/80 an hour/day. Some places ask for a deposit of about M$100. David (044-998-860-00-75; Av Rueda Medina), near Abasolo, has a decent selection.
