We rented Casa Tucan, a house across the road, in February. Beach access was a bit difficult. There was a trail south of our home and we were able to access the beach with a 5 minute walk, but someday when all the beachside lots are filled with homes, there will be no easy beach access. We had hoped to be able to walk north along the beach but are unable to do so due to a rock wall built up and into the water at a condo complex. Couldn't find another beach access from the road on the north side. This was very disappointing. That being said, the bay is pretty, much quieter than Akumal Bay and has great snorkeling. Due to how the reef is situated, it can be very wavy when the wind is up. If it is then the bay at Akumal is usually better for snorkeling. There are some sandy patches on the beach, but there is a bit more coarser sand and some gravel like areas and small rocks. Water shoes are recommended. We navigated in and out with our fins on. It is quite the jaunt swimming out towards the reef. There is the occasional coral formation along the way and most of them have a couple fish hanging around them. The closer to the reef, the better the sea life. It is a bit of a maze navigating at the edge of the reef and one needs to be careful not to touch anything. This is made difficult with the current that pulls you - but we never felt it was dangerous. We are all experienced snorkelers and did not have a problem - the youngest was 11. Not sure if you did not stay in this area, where you would park to access the beach, but perhaps another review answers that! Hope this review helps someone!
