The ruins of Copán are about a kilometer east of Copán Ruinas  on the road toward San Pedro Sula , set off the road in a six-hectare wooded archaeological park along the edge of the Río Copán. After buying your US$15 entrance ticket, walk up the path from the visitors center (where there is a small cafeteria and gift shop) through tall trees to the entrance gate, where a guard will take your ticket.
If you’d like to enter the archaeological tunnels, buy an additional ticket for US$15 (a high price for the experience, recommended for archaeology buffs only). (Tickets for the adjacent Museo de Escultura Maya  are also sold at the visitors center, US$7 and highly recommended.)
Much of the original sculpture work at Copán has been removed from the grounds and replaced by exact duplicates. Although this is a bit disappointing for visitors, it is essential if the city’s artistic legacy is not to be lost forever, worn away by the elements and thousands of curious hands. Most of the finest stelae and carvings can now be seen in the Museo de Escultura Maya .
Just before the place where the guards check your ticket is a kilometer-long nature trail with examples of ceiba, strangler fig, and other plants characteristic of the jungle originally covering the Valle de Copán, worth taking a brief stroll along either before or after visiting the ruins.
