We borrowed our hotel's snorkel gear and drove up around 9:30am to check our what we called "Steps Beach", but what is officially known as Tres Palmas beach. We found free parking easily on the road down to the beach, but things were already filling up by the time we left. The walk from the car was a little difficult barefoot (jagged rocks and some broken glass) so you may want to keep some flip flops on until you get to the beach. We hid our keys in the tshirt we left on the beach as we snorkeled. Some reviews have already mentioned that it can be a little bit of challenge to enter the water, but there was a calm, less-rocky section that we were able to enter from easily. The snorkeling was nice - lots of fish and some coral. It's definitely worth a visit while in Rincon. I wouldn't hang out for the beach, as I think going earlier in the day or perhaps even later in the afternoon was perfect for snorkeling.
