To get there by bus, catch a bus toward Benque Viejo del Carmen at the main terminal. Tell the conductor that you are heading here, and they will drop you off for $1Bz. Cross the river via free hand cranked ferry, and then walk 1 mile to the site. It is also easy to hitch a ride from the San Ignacio vicinity. Admission to the park is about $10B. Park closed at about 4:00 pm. The ferry takes only one car at a time-so sometimes there is a line up to leave if you wait until 4:00 pm. It is the only way across the river.
