This effort includes better roads, visitor headquarters and encouragement of construction of environmentally sound hotel accommodations. There are frequent organized tours to most of these sites, access by rental car is easy, and the hardy traveler can also reach most sites by bus. Some sites, however, are only for the most determined visitor, and are at the end of bad roads, require overnight camping in the jungle, or journey by river craft. Admission fees to most sites range from 15 to 25 pesos, but shooting amateur video requires a special permit for 30 pesos. This permit may be purchased at any site, and is good for all other sites visited that day.
Entry is free on Sundays.
