The low, pyramid-like structures at this modest archaeological site date from as early as 1500 BC. They have been excavated and restored, along with a small tomb and a ball court (unusual in western Mexico). The structures are oriented due north toward Volcán de Fuego, which makes an impressive backdrop on clear days.
It’s about 5km north of Colima city and easily accessible by buses 7 and 22; taxis cost M$45. A word of warning: wear good shoes and socks because there are lots of fire ants.
