Blue lagoon comes under conservation area,so you will find it clean and secluded. It's definately beautiful but the aerial view is far better thn being there. One side of lagoon has pebbles and sandy on other side. We visited in early may so was not much busy but it gets quite busy in peak season. Worth visiting once if you are visiting Olu Deniz already but a specially planned visit from far may turn a bit dissapointing .
