Don't expect towering stone pyramids like Tikal; these are grass-covered mounds of clay and pumice right in the middle of the city. Head straight for the 'Acropolis' section to see the best excavations. You will likely see modern Mayan ceremonies at the living altars, so stay respectful and keep your distance. Spend about an hour here. A private tour helps navigate the sprawling site and explains why this mud-brick city actually mattered. Skip the midday heat.
