The village of San Miguel del Valle is one of the gateways to great mountain biking in the high country of the Sierra Norte mountains near Oaxaca city. Tucked into a fold of the mountains on the north side of the Tlacolula valley (one part of the Valles Centrales of Oaxaca state), San Miguel is reached by driving north from Tlacolula and passing through the municipio of Diaz Ordaz. San Miguel itself is part of the valley, but it lays claim to miles of mountainous terrain abutting the Pueblos Mancomunados. Once you have reached San Miguel, you should check in at the ecotourism office on the town square (the bright green building next to the municipal building). There is a 50 peso fee for hiking or biking on communal land. The charge is worth it, though, as there are miles of great trails, most of which are mapped and are well marked with signage — which is rather unusual hereabouts! Guides may also be hired at the ecotourism office for 150 pesos for three hours work. The office may be contacted at 951-520-9105. The person in charge in 2016 is Sergio Lopez Garcia.
The ride that is featured below is a 12.9 mile (20.7 km) loop utilizing dirt roads running through the forest. The loop can be ridden in either direction, but we recommend going counter-clockwise, hitting El Carrizal first and then continuing on to La Neveria and La Ventosa. Why? The road drops rather steeply from the El Pedimento trailhead (again, well marked and easy to find) to El Carrizal, losing 1134 feet (346 meters), with only 651 feet (198 meters) of climbing along the way. This would be a painful climb out if you ride the loop clockwise. The distance from the El Pedimento trailhead to El Carrizal is just 4.4 miles (7.1 km). The road from El Carrizal to La Neveria, on to La Ventosa and back to the El Pedimento trailhead runs 8.5 miles (13.7 km) — a greater distance, but with gentler climbs alternating with some mild downhill sections. An alternative — for those who like to finish a ride going downhill rather than up — is to start the ride in El Carrizal, ride counter-clockwise and finish with the screamer of a downhill back to town. The overall elevation gain & loss riding around the loop is 2219 feet (676 meters).
