Does anyone know how to get from Ciudad Hidalgo to the Sierre Chuacua Monarch Reserve?
I assume you mean Santuario Chincua:
Are there buses on this route or is it taxi only?
THere should be collectivos and buses running to Angangueo, its the little town just outside the Sierra Chincua reserve. From Angangueo you'll find tours and taxis to Sierra Chincua. Enjoy! This is my favorite reserve.
According to Google Maps Chincua is closer to Cuidad Hidalgo than to Angangueo, just over 30km.
Can we get tour guides and taxis to Sierra Chincua from Ciudad Hidalgo?
i assume you plan to stay the night there, so why not ask your hotel?
