Honduras has a reputation that is enough to scare off most visitors from making a lengthy visit. Fortunately Copan Ruinas is very close to the Guatemalan border and is easily reached from there both independently or by tour/tourist shuttle. There are several sections to this site including the museum and tunnels and with all the separate fees it is one of the more expensive Mayan WHS to see. 

We covered the most central parts and didn't make it out to the Sepulturas section and it still took us a couple hours. Compared to other Mayan ruins what really sets this one apart is the quality and quantity of stele and carved detail, especially in the hieroglyphic staircase. It was nice to visit without huge crowds and still be able to climb over large sections. The huge trees still growing out of the rubble make for some great photos too. 

The nearby bird park has also been reintroducing Scarlet macaws to the area and there were a couple dozen hanging around near the entrance. They are beautiful birds and it's not surprising that the Mayans of Copan used a lot of macaw imagery in their hieroglyphics and decor throughout the site too. I only give it 4 stars though because a full visit to the site is overpriced for the region.
