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.
A 383 km round trip from Aculco de Espinoza - roughly 7 h 46 in the saddle. On the way it passes Stretch of the Camino Real between Aculco, Cerro Altamirano, Monarch Butterfly Biosphere Reserve and back through Cerro Altamirano. The stored terrain estimate reaches about 2,750 m; a measured road-elevation profile is not available. A steady touring day rather than a sprint.
Waypoint introductions and full write-ups
1. 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.

2. Stretch of the Camino Real between Aculco
For almost three centuries, wagon trains loaded with silver rolled north and south along the Camino Real de Tierra Adentro, the royal road that linked Mexico City with the mining towns of the north and eventually with Santa Fe in what is now New Mexico. It was one of the longest trade routes in the Americas, carrying silver, mercury, goods, people and ideas across thousands of kilometres. In 2010 UNESCO listed a series of sites along the route, including stretches of the old road, bridges, haciendas and towns. This section, between Aculco and San Juan del Río, crosses the high plateau on the border between the State of Mexico and Querétaro.

Stretch of the Camino Real between Aculco comes up about 27 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 102 km into the recorded legs you reach Cerro Altamirano. Next is Monarch Butterfly Biosphere Reserve.
4. 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.
