Here's some beach artwork created on the remote fourth beach in Morro de São Paulo in Brazil. It didn't last very long as the tide came in pretty rapidly. A horse rode over it as well just after I took the photos.
There are no cars allowed on the island so your bags are carried by small children in a wheelbarrow.
Right on the beach they have little vending carts that will serve you very cheap (and very strong) fruity cocktails. The papaya caipirinhas was especially delicious.
