The La Reina trail is a very steep gravel road which links San Andres Huayapam with the ecotourism camp at La Cumbre Ixtepeji at over 9000 feet in altitude. This is a killer climb and, conversely, a screamer descent. The elevation gain amounts to 2378 feet in the space of 3.7 miles, with a gradient of 20% in some places. Your legs and lungs better be in top condition and your bike equipped with a good granny gear to make it to the top; and your brakes will get a heck of a workout on the way down. The map below shows the way, but note that this ride stopped short of the top of the mountain. Access to the trail is from Martires street. Note: there is a fee of 50 pesos (in 2024) to use the trail, payable at a toll booth at the bottom of the road just outside Huayapam.
