Snow leopards, monarch butterflies, penguin chicks and starlings
The first morning sunlight begins to pierce the forest canopy and then, one by one, the butterflies take to the air. Before long, there are small groups fluttering upwards together, and then great ribbons and swathes of burning orange as millions of delicate wings unite. It is worth the early alarm and challenging climb to see monarch butterflies at the El Rosario butterfly sanctuary (open mid-November to late March), situated in the Monarch Butterfly Biosphere Reserve. These insects embark on an epic annual journey south to overwinter in Mexico’s oyamel fir trees.
