Small-group nature tours from Monterrey in English, with hotel pick-up, running since 2015 — they began as Noreste Adventures. They publish no address, so the pin is on the city.
The walls of La Huasteca canyon, including the climbing area, and the dry side-canyons; the cable car and caves at Grutas de García; a sunset hike on Cerro de la Silla from the teleférico; and a Chipinque sunset walk that comes down by headlamp. In town they run a Barrio Antiguo food walk through at least three places.
