Waypoint introductions and full write-ups

  1. 1. Historic centre of the city of San Juan de

    San Juan del Río grew up as a stop on the Camino Real de Tierra Adentro, the royal road that ran north from Mexico City to the silver mines of Zacatecas and on to Santa Fe in New Mexico, and its historic centre is one of the sites along that route listed by UNESCO in 2010. For centuries, mule trains, wagons and travellers passed through here, stopping at inns and crossing the river on the stone bridge built in the early eighteenth century, which still stands. The centre has plazas, churches, convents and colonial houses of pink and grey stone, and a relaxed provincial atmosphere, despite the city's growth as an industrial centre.

  2. 2. 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.

  3. 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.

  4. 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.
