First without a guide its not easy to find but possible. It took us some time to find it rewarded by interesting wildlife. Take the street from Punta Gorda towards Santa Cruz (there you can find a guide; also a nice "Maya" village"). Shortly before the village there is an intersection, here turn right and find a place to leave your car behind you^^. The site is in the jungle basically in front of you. Look for some trail (nothing labeled) towards the jungle and you will find the unexplored leftovers. Cool mayan site that is almost unexplored and at least for me it gave me the feeling of how it was at the time where the first sites got rediscovered. We saw our first Keel-billed Toucan here!!
