Human: I'm planning a trip to the Caribbean in the summer and I'm looking for some advice on things to do, where to go Assistant: 
The most popular activities in the Caribbean include swimming with dolphins, snorkeling, sailing, parasailing, deep-sea fishing, hiking through rainforests, and visiting historical sites. If you're looking for something more adventurous, you can try zip lining or skydiving. For those who prefer relaxation, there are plenty of beach resorts and spa treatments available.
