Lonely Planet review for Museo Miraflores
Museo Miraflores is an excellent, modern museum inauspiciously jammed between two shopping malls a few kilometers out of town. Downstairs focuses on objects found at Kaminaljuyú, with fascinating trade route maps showing the site's importance.
Upstairs there are displays on textiles and indigenous clothing, separated by region, from around the country. Signs are in Spanish and (mostly) English. Out back is a pleasant grassy area with paths and seating - a good place to take a breather. To get there, catch any bus from the center going to Tikal Futura and get off there. The museum is 250m down the road between it and the Miraflores shopping center.
