I only give 4 stars even though the site itself is well worth 5! Indeed we saw exceptional marine fauna as well as various varieties of fish, starfish, sea cucumber, and a well-hidden octopus. It's an extraordinary spot! Unfortunately, the lack of respect for tourists is real. I picked up trash in the water, what a shame..! Another vacationer in front of us brought back a starfish to show it to his wife and throw it at the water's edge even though we had seen it a few minutes earlier, well in its place in its natural environment and very much alive! From there, obviously curious children rushed to pick it up in their nets for mom and dad and take a bunch of photos while our poor star heated up in the sun! My companion got up, went to get it and put it back at the bottom of the water in its place... If only people could respect nature! Go take a trip to the biodiversarium in Banyuls and I guarantee that you will perceive things differently, and understand the life and roles of species, as well as underwater vegetation.
