Cayo Arena, also known as Cayo Paraíso, is located 25 minutes by boat from the starting point in Punta Rucia, located northwest of Puerto Plata. This sandbar sits in the middle of the brilliant blue ocean, with powdery white sand and shallow water teeming with tropical fish, ideal for snorkelers of any level, or you can also choose to scuba dive. Most tour operators offer the round trip from Puerto Plata, including the boats that will take you to the key with snorkeling equipment included.
