Most of the resorts have the banana,jet ski and skiing although the bigger ones may have some sailing and para sailing too.Cala Llonga and Escana ,when I last visited two years ago came into the first catagory.para sailing was available at Sargamassa,only a couple of miles from Escana.
I hope my info is not out of date but if so I'm sure someone will put me right,John.

I've just returned from Es Cana, where the weather is hot hot hot

Lots of water sports available on the beach, including pedallos, miniture hovercrafts, banana boat, ringo, flyer, parasailing and speedboat rides, but did not see any jet skis. Water is warm and clear with very few jellyfish. Glass bottom boat and ferry to Formenterra also available.

Hope this helps with your choice of resort

The only resort that doesn't booast a lot of water sports is Santa Eulalia, which suits the more relaxed and adult feel of the town.

Es Cana is very good for watersports, probably the best on the island (?)
