Absolutely fabulous day. We were collected from our hotel at 7:30 am and driven by mini bus to Sian Ka'an, collecting other people en route. Here we were split into 2 groups of 6 and boarded our boat to tour both the mangroves and the sea. We saw manatees, dolphins, sea turtles but no crocodiles on our trip, plus loads of birds the frigates were amazing and we also saw osprey, pelicans, cormorant, heron, egret and one lone flamingo whose migration had gone wrong.
We had never snorkelled before and the experience was amazing. The coral and tropical fish were beautiful and we thoroughly enjoyed this part of the trip we had plenty of time in the water and were not under any time pressure throughout the whole day.
The tour finished with a late lunch at a restaurant in Punta Allen hot buffet which included chicken, fish, rice, bread and pasta. Arrived back at hotel at 5:30 - tired, but very happy.
Top tips: wear swimsuits under clothes rather than trying to change when you get there, re-apply sunscreen a lot we did get a bit burnt despite our best efforts, towels are a bit pointless as you dry off quickly on the boat so they are just another thing to carry, shoes and other possessions will get wet, no need to take water as guide provides a bottle each.
All in all, a real highlight of our holiday.
