Beaches: Playa Delfines (Dolphin Beach), also known as El Mirador (The Lookout), is located at km. 20 in the Hotel Zone. Most of the 14 miles of beach in Cancun are absolutely beautiful, but What makes Playa Delfines exceptional is the fact that there are no hotels, restaurants, or anything else built on this beach. It is easily accessible by bus or there is free parking available and chairs and umbrellas for rent. There are also clean, well-maintained restrooms available and no beach vendors to speak of. There are lifeguards but the water can be very rough here so swim with extreme caution.
