As most reviewers have mentioned, this is a fantastic full day of activities. Erin was an excellent guide who really went out of her way to make sure the trip was as good as it could be. The fun thing about this trip is that several of the activities were things that you simply would not be able to do easily without a guide. And with a guide it was a safe, fun and rewarding experience. Some details of the trip:
You do get wet, and you do get into areas where there could be mosquitoes. That said, they provided full coverage bug shirts, and because of a slight breeze, and I suspect because until recently it had been fairly dry, I did not need to use the hood and I was not bothered by mosquitoes. If you are careful you can stay out of the deep water and keep around knee deep, at least in the conditions we were in.
I brought my smaller camera and a dry bag, but I would have been comfortable bringing my DSLR and long lens. This would have been useful on the "dry" walk and in Florida Bay, but in the mangroves a long lens would not have been helpful. There was never a time when I was worried about getting my camera wet, as long as I was careful. The trip is not photography focused but there was plenty of opportunity to take photos.
You do get close to gators, but Erin was careful both to keep us safe and keep from unduly disturbing them (disturbing them probably would not help keeping us safe).
Overall this was absolutely a wonderful trip, so much so that we will certainly consider doing it again the next time we return: each trip will be totally unique because of weather and what animals are moving about.
