Sea Trek on De Palm Island was the coolest thing we did on the trip and as soon as we had finished, I would have done it again. We were given a quick lesson and felt very safe the entire time. The next best thing to scuba diving without the lessons and required certification. There were so many colorful fish amongst the wreckages down there and they provided food to feed and attract them. We signed up through the hotel and you could either pick a full or half day on De Palm Island. We chose a half day and were satisfied with that. Included in the price were transportation to and from the hotel, the Sea Trek Adventure, and unlimited drinks and lunch. The food wasn’t gourmet and the drinks menu limited, but the Sea Trek adventure made up for whatever was lacking.  Great fun!
