I went tubing last June with my wife and another couple at Jaguar Paw. It was an AWESOME experience and I would highly recommend it. Yes, the jungle walk to get to the river was an added bonus to the experience. No problem with bugs, although we did apply bugspray for the jungle walk. NOTE: if your schedule is a little flexible, I would make sure you go on a day when there are no cruise ships in port. The day we went, we were the only 4 people in the river! But the previous day, they had had 300-400 people through! Just a thought. You will definitely need some type of foot covering (no flip-flops or sandels) but the rubber-soled "water socks" should do just fine. Enjoy!
