Easily the best land/beach activity in Siesta. We met at the main public beach access where the bikes were adjusted for size to each person and then given a quick lesson in how to use the bikes. From there we cruised the beach all the way South, all the way North then back to where we met. Our guide was fun, funny and informative. Plenty of opportunities to take beautiful photos and to have photos of you taken by the guide. It ended with a picnic, but we skipped it so I canāt comment on that part.
Definitely worth doing, we had so much fun!
