Between the tiny towns of San Pedro and San Pablo runs the Tiquina Straight, a narrow waterway that connects the main body of Lake Titicaca with the smaller, outer lake of HuyÃ±aymarka. If you are traveling between the Lake and La Paz, or elsewhere in Bolivia, you will have to pass across on a small ferry ($0.50, 10 min.); your vehicle will follow on a larger raft. Though your bags will be safe enough floating across on the bus/van/car, its best to keep your valuables on you. Another quick tip: have your passport handy, as San Pedro is home to a naval base, and officials do random checks of foreign identification. If youâ€™re craving a quick snack between bus and boat, there are some small restaurants and food stalls presents, just donâ€™t miss your ride.
