Hi Big John,
Yes there is horseback riding. The 4 resorts are all within walking distance of each other, and between Gran Club and Brisas, there is horseback riding. Every year, I say I'm going to do that, but the 2 weeks are up before I get around to it. I do know it's quite affordable.
There is also great snorkeling just off the beach at Caracol, horse and buggy rides to coco beach, catamaran trips, one to Playa Bonita beach, and one to Iguana Island. Tours to the city of Camaguey also available. Disco next door at Gran Club, as well as dancing and show at Mar Verde (the cultural centre next door to Caracol) after the show at the hotel.
The entertainers will be happy to take you there if you're interested. Lots of beach volleyball in the morning, bocce ball and dance lessons of course.
Sorry...i kinda went on and on....If you want to do a tour of Camaguey, pm me, and I'll tell you who to talk to at the hotel to get a taxi for your family. The driver is fluent in English and will give you a great tour.
If you have any other questions, ask away,
Cheers,
Beachlover
