Zaculeu was the fortified capital of the Mam Maya kingdom, perched on a natural platform above deep ravines on three sides — a position that made it nearly impregnable and explains why it held out so long against the Spanish. The site is about 4 km from central Huehuetenango and easy to reach by tuk-tuk or taxi.
The ruins consist of several pyramids, a ball court, and a series of plazas, all covered in the distinctive white plaster that gives the site its slightly unreal, model-village appearance. Despite the controversial restoration, the setting is genuinely impressive and the place receives few tourists, so you can explore the platforms and staircases in near solitude. A small museum at the entrance covers Mam Maya history and the background to the restoration. Admission is inexpensive.
