Last year we took the French Riviera Rendezvous to Orient Beach. This was a great tour. We love the beach! Lots of waves. Down fall to this beach. Lots of people on the beach selling things. They move on with a no thank you. If nudity bothers you then you might not want this tour. You do have people walking the beach without clothes on (it's allowed on all French beaches). It really didn't seems to raise any eyebrows with the folks on our tour. The only time I think it bothered us was when a really old, hairy (bear type hairy) guy walked down the beach.

There are some people who shouldn't walk naked anywhere!

This was a really nice tour & the food was good. I think it was about $5.00 for the unbrella for the day. We recommend renting one. It does get hot. But over all we loved this beach & would go back again.
We have also taken the Golden Eagle tour. This one too is a great tour! Love catamaran sailing. The only problem is that it wasn't long enough! The island where they take you is pretty & has lots to explore. The snorkling is nice but can be rough drepending on the water. Again this is a tour we would do again.
Hope this helps! Enjoy your cruise!
