Getting there & away
Xilitla has regular connections on comfortable 2nd-class buses to Ciudad Valles (M$54, frequently) that pass Aquismón en route. Buses to Tampico (M$200) also run frequently. There are also buses to San Luis Potosí (M$350). The southeast journey across northern Veracruz state toward Tuxpan is actually quickest traveled via Valles and Tampico.
The drive through the Sierras to the market town of Huejutla on Hwy 85 is fantastic. If you pass through Huejutla on a Sunday there’s a big market, which many Nahua people in the region attend.
South of Huejutla, Hwy 105 climbs into the lovely Sierra Madre Oriental. It’s a tortuous, foggy road to Pachuca. On the way you’ll pass old monasteries at Molango and Zacualtipán.
Hwy 120, heading west to Jalpan then southwest toward Querétaro, is an exciting route through the Sierra Gorda. Southeast of Xilitla, Hwy 85 is the most direct route from the Huasteca to Mexico City. It’s a steep but scenic route over the Sierra Madre. Start early to avoid fog.
