Mexico's Yucatán Peninsula — anchored by Ascension Bay, Espíritu Santo Bay, and waters around Holbox and Cozumel — is one of the world's foremost saltwater fly fishing regions. Mexico's permit run large, often fifteen to thirty pounds, in numbers that don't exist elsewhere in the Caribbean. Days with dozens of permit shots are a legitimate expectation at top lodges, and the guide community has made permit fishing an art form.

The "Yucatán Slam" — permit, tarpon, and bonefish in a single day — is a real possibility at the best Mexico fly fishing lodges. Snook fishing in the mangroves is outstanding for anglers willing to throw large poppers at night. Mexico's proximity to US hubs, quality lodge infrastructure, and diversity of species make it one of Front Range Anglers' most consistently booked international destinations.
