Distance and timing basis
Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
564 km from Mineral de Angangueo to Mineral de Angangueo, about 11 h 05 of riding. On the way it passes Cerro Pélon, Cerro Altamirano, Town of Aculco and back through Cerro Altamirano. The stored terrain estimate reaches about 2,750 m; a measured road-elevation profile is not available. It was put together for the scenery rather than the shortest line.
Waypoint introductions and full write-ups
1. Monarch Butterfly Biosphere Reserve
Between November and March, the fir forests on the mountains of central Mexico turn orange. Millions of monarch butterflies, which have flown some four thousand kilometres from Canada and the northern United States, cluster on the oyamel firs at about three thousand metres, hanging in dense clusters that bend the branches. In the warmth of the sun they open their wings and fly, and the air fills with soft movement, a sound like rain falling on leaves. Nobody knows exactly how they find the place, since the generation that arrives has never made the trip before, and the mystery adds to the wonder. The Monarch Butterfly Biosphere Reserve, on the border of Michoacan and the State of Mexico, protects the wintering grounds and was listed as a World Heritage site in 2008.

Planning note
Monarch Butterfly Biosphere Reserve is where the day begins. Next is Cerro Pélon.
2. Cerro Pélon
Every winter, something close to a miracle arrives at Cerro Pelon. Monarch butterflies, which have flown from Canada and the northern United States, a journey of some four thousand kilometres, gather in the oyamel fir forests of the high volcanic mountains on the border between Michoacan and the State of Mexico. They cluster in the millions on the trunks and branches, so thick that the boughs bend under their weight, and when the sun hits them they leave the trees in a swirl of orange that sounds like rain. The sanctuaries here are part of the Monarch Butterfly Biosphere Reserve.

Planning note
Cerro Pélon comes up about 84 km into the recorded legs. Next is Cerro Altamirano.
3. Cerro Altamirano
Every autumn, millions of monarch butterflies fly thousands of kilometres from Canada and the United States to spend the winter in the fir and pine forests of central Mexico. Cerro Altamirano, near the village of Contepec in the state of Michoacán, is one of the mountains where they gather, part of the Monarch Butterfly Biosphere Reserve, a UNESCO World Heritage Site. When the butterflies are here, roughly from November to March, the branches of the trees are covered with them, so thickly that they sag under the weight.

Planning note
about 227 km into the recorded legs you reach Cerro Altamirano. Next is Town of Aculco.
4. Town of Aculco
Aculco is a quiet stone town in the northwest of the State of Mexico, on the high plateau at well over two thousand metres, where the Camino Real de Tierra Adentro, the colonial road to the north, passed through on its way from Mexico City. The town was a staging post, and its well-preserved centre, with a broad plaza, the Franciscan church and convent of San Jerónimo and old houses built of pinkish stone, is part of the UNESCO listing for the route. It was here, in November 1810, that royalist troops defeated Miguel Hidalgo's insurgent army, an early setback in the War of Independence that people still mention with a kind of local pride.
