On our last trip a few weeks ago, we walked in the early morning (around 7 A.M.) from the village and headed toward Club O beach wearing our T-Shirts and gym shorts. Once we reached the rocks, the suits came off and we continued down the beach and turned around near Papagayo's and headed back toward the village. During our Club O section we noticed a couple in the water but they had their suits on and then further up, about 1/2 way between Papagayo's and the rocks there was a group of 3 women walking toward Papagayo's and they were all wearing clothing. Finally just before the rocks we again had another couple walking in the opposite direction but they too were clothed. Once we were near the rocks we again put on the shirts and shorts and continued to our rental in the village. I definitely would have had reservations going any further north of the rocks without clothing of some sort.
