Better facilities are being built at the Actun Tunichil Muknal site.
"Under the Sustainable Tourism Project (STP), several Archaeology Reserves will be receiving funding for various infrastructure projects. ATM is the most documented site in the country, and one of the most superior subterranean sites in the region. Tour operators/numbers are controlled by license with 95% of all tours to the site originating in San Ignacio Town. Current facilities are almost non-existent, therefore investments will be made to: 1. Design and construct modern bathroom, changing and restroom facilities to cater to an increase in current visitation; and 2. Construction of a ticket/security booth onsite in conjunction with landscaping of the site entrance and car park area."
This is the floor plan of the construction being carried out at ATM for the new bathroom facilities.
