For NorthernMelody re: Topside in Utila:
Horseback riding, Sterlin is an AWESOME guide!
Hiking, the Bat Cave is kinda cool but Batman & Robin were off that day, the freshwater cave was also fun.
Patrick's has an assortment of water toys/trips to rent, jet skis, banana rides, parasail (weather permitting), among other things.
A water taxi out to Water Cay for the day was fun.
Sailboat charters (somewhat seasonal depending on who's in port)
The Whale Shark excursions
My personal favorite aside from the trail rides is to rent an ATV & hit the back roads to go exploring. There are some pretty amazing unspoiled places in Utila if you just get out of town a bit.
There's also a 'Movie Theater', and if you need to work out, there's a new Gym that's very well equipped & offers daily, weekly, monthly & yearly memberships. There's also some great small bars/restaurants that are great places to meet people from all walks of life & nationalities.
And of course, this IS still Honduras, so there's always a football(soccar?) game up at the field.
Pretty much everything is within walking distance or a short bike ride (which are available for rent).
Utila is VERY laid back, think Roatan 20 years ago, long before the cruise ships & condos. It has an amazing mix of people from the local culture, to the various nationalities that have come here to do dive courses.
If you want more info, feel free to PM me & I'll help with what I can.
