My 30 yr old son will be going in 3 weeks. He doesn't have a computer so I need to ask questions on his behalf. He just wants to wing it while he's there, talking to the locals, absorbing the culture, relaxing and a little bit of adventure too. He wants to spend time at the beach and take a trip through the rainforest. He'll bring some natural mosquito repellant and sun block but aside from that, is there anything special he will need to protect himself from the elements and bugs that abound?
Thanks for any suggestions.
