I had the pleasure of being in Utila for 10 days earlier this month. Although I am not a scuba diver, I am a very avid snorkeler. We stayed at Slumberland Villas in the Blue Bayou section of Utila. Snorkeling was very good right offshore with great coral formations, although the water was slightly murky. I'm picky and would like to see 100 ft. vis like you get in Curacao or Cozumel, but off Slumberland the vis was typically 30-40 ft. Blue Bayou is pretty much the only place on Utila that has good offshore snorkeling and from which you can walk or bike to Utila town.
