The bus system is very limited. Busing between the beaches can be very hard with one every 4 hours sometimes. Even a 15 minute taxi ride can be $8, as expensive as most western nations. Most lodges have bicycles for rent. Taxis hang out in the center of town and will take you anywhere you want to go up and down the coast. When taking a taxi, make sure to negotiate your price ahead of time. Most of the taxi drivers know the area extremely well and can find their way with just the name of your hotel.
