Nice beach, stayed close to the entrance in our 2wd.
Make sure you memorise the way you came in and don't forget it as we did - ended up in a very sandy road and got stuck! XD Helpful Americans got us out in no time! Main road otherwise is good and easily doable in a 2wd.
No one came to collect money.
There is a nice trail behind the sand dune at the end which takes you to a nice beach and the back section of Puerto Escondido.
