You can easily walk anywhere in Copán Ruínas, including from town to the archaeological site. However, if you need a taxi, they are plentiful and inexpensive. Most of the taxis are small motor taxis or tuk tuks, which circulate around town and gather on the north and south sides of the central plaza. A taxi ride between town and the archaeological site should cost L20 per person.
