Dive into the Dominican Republic's ultimate underwater adventure with Seaquarium. Pop on a special helmet with air supply and explore the colourful marine life, looking out for a sub wreck on your seabed stroll. Back onboard, you'll be treated to a Caribbean party like no other - snorkeling with sharks and stingrays is thrown in for good measure. Cap it all off with a leisurely dip in the natural pools of the Caribbean Sea - an extraordinary half-day excursion you won't forget.

The snorkeling was brilliant and also using the helmet under the sea. Lots of different fish to see with also a wreck at the bottom. The dolphins and sea lion along with swimming with sharks and stingrays imo is animal cruelty. Yes there in the sea but in small pools caged/netted off. Shouldn't be locked up like that. 40+ did it, get out and the next lot go in. Not how was advertised and not for me.

All in an awesome and entertaining trip. The sea aquarium was a lot of fun, the staff were great, plenty of rum. My only negative is that I wish they had informed us before booking that the sharks and rays were being kept in captivity alongside dolphins which I don’t want to support.

Very different but good experience. The diving was good and something that I have never experienced before (I have scuba dived before but this was completely different). Day was good with lots of drinks available and some fruit and ham sandwich provided. Staff were helpful but had limited English so difficult sometimes to understand. Varied day with lots of little things like snorkelling, seeing dolphins and sea lions. Boat did not have a lot of shade so definitely lots of suntan lotion.
