You'll also need sturdy walking shoes for navigating the extensive area of the ruins. If you have room in your day pack, a pair of binoculars is wonderful for the vistas and wildlife viewing. The forest canopy obliterates all light, producing the type of darkness best described as not capable of seeing your hand in front of your face. With mosquitoes and other forest insects, long sleeves and long pants are recommended. A mini-van will drive you the remainder of the way and can be prearranged as part of a tour, or, with some patience, arranged once you get there.
Bus service is also available, with a walk into the area from the main road.
Travel by road, with the exception of east-west with Belize, is not recommended. The trip holds many hazards that are best avoided at this time, even for the most rugged and seasoned of travelers. There are a couple of hotels, including Westin's Hotel Camino Real and the Jungle Lodge, within minutes of the path to the main ruins. Hammock spaces are available for a low nightly fee, but space is limited. Vendors and a small row of eateries provide morning and nightly activity and merriment.
