Coba, a Great Place to Climb a Pyramid
The Yucatan Travel Movie includes a visit to Coba, including a climb up Nohoch Mull, a very steep, 12-story tall pyramid. Coba is described in the following blog:
Another famous Mayan city is Cobá, located 40km west of Tulum. Cobá is especially fun because it has one of the few pyramids that can still be climbed. In total, the grand pyramid has over 120 steep steps that require careful footing and lots of sunscreen. The view, however, is breathtaking, as you see the surrounding jungle and peaks of smaller temples sitting between tree tops. The remainder of this ancient Mayan city is great for walking as all the temples are connected via well-maintained walking and biking paths under shady trees.
