Hi Sol37, my partner and I were at GBP Cayacoa in June. Wont comment on dolphin and sealion encounters as they should be in the ocean, not held captive!! Must tell you though, we had two days out with a guy whom lives in Samana, his name is Terry Lee Bandi, who is an american. We were driven in his 4*4, and visited Devils Blow-hole, which was just awesome! Also went to Rincon beach, which will blow you away, a trully beautiful beach, also had lunch there. Lots of time for swimming and snorkelling, and lots of stops at places of interest. Next day we went to Limon waterfall, the horses at this place are amazing, taking you down the trail, and the guides stay with you from start to finish. The waterfall is breathtaking, and a definate must-see!! After our adventure we had a really hearty lunch, which was simple but delicious. We then went off-road to Playa Moron, another beautiful beach for a few hours. Throughout these trips Terry stayed with us, and we felt completely safe. If you want some trips which are fun and exciting, slightly adventurous, with a guide who cares that you have agreat time, then forget the usual boring bus trips by holiday companies. Give Terry an e-mail, all of your family will have some days out you will never forget, and thats a promise. He is a member of trip adviser, should have no problem contacting him. Have a great holiday, it really is a wonderful country! Fiona
