The Museo Popol Vuh is an important collection of Mayan artifacts. This treasure trove includes everything from a model of the city of Tikal where the tallest pyramid in the Americas makes its home, to impressive funerary pieces and Mayan pottery. There is a small fee if you want to take pictures, but no worries, the chocolate the lady at the front door will give you makes up for it! Figure one to two hours to take in this collection. It will be time well spent.
