The butterflies generally hang out in this area from November to March when it's too chilly to stay in North America (Great Lakes area). Despite the fact that it was a beautiful day all around, on the hillside, in the forest it was cold! Cold enough that the butterflies were not really in flying mode, but more like huddling on trees mode. It was a good few kilometers hike up and down and overall a great excursion. We ended our visit with a hot blackberry drink, thick like sahleb and very tasty. But enough chatting, here are the pictures:
Those clumps are actually butterflies:

And even closer:
Driving from Guadalajara- take highway Mex 15 until Maravatio, where you turn south towards Angangueo (for 4*4 vehicles) or Ocampo (for little cars). Door to door, it's about 5 hours, and the cuota comes out to appx. 500 MXN each way.
Alternatively, from Morelia it is appx. 2 hours.
The Park- From Nov. to March, 9am to 6pm. The best time to come is in on a sunny day in Feb/March when the butterflies are more likely to be moving around. Try to come mid-day/early afternoon. It's about 2-4 km uphill hike; horses also available. Entrance is 40 MXN/adult.
