The island itself is just 11 km long and 4 km wide. Scooters, ATVs, and mini-taxis called tuktuks are the transportation of choice.
Most days we walked 15 minutes to go snorkelling right off a dock. (That little blip in the water in this picture is Elizabeth snorkelling.) It was a very short swim to a great outcrop of coral reef that follows the edge of a deep dropoff in the sea floor. In the distance, we could see the mountains on the mainland.
We didn't have an underwater camera so I will share a few pictures from the creative commons that look like some of the things we saw:
In the evenings we watched the sunset from the small beach near our hotel.
After about a week on Utila we were a little waterlogged and ready to see what the mainland had to offer.
