We're coming to Bocas Town next week with two teenagers who will likely spend hours in the water. Just reading Open Road's Best of Panama which says that "all of the bars, restaurants and other businesses fronting the water pipe their waste from toilets into the seemingly inviting sea ... and hotels have water slides and other water toys to facilitate this." Is this true and is it safe to swim there or should swimming be done further away from town? Any suggestions of where to swim safely would be greatly appreciated. Thanks!
