Mexico City

Tacos, free museums, cafe culture. A megacity that feels like a neighborhood.

One of the world's great megacities is shockingly welcoming for solo travelers. Roma and Condesa neighborhoods have cafe culture that invites lingering. The street food — tacos al pastor, tlacoyos, esquites — is so good it gives you an excuse to talk to every vendor. World-class museums are free on Sundays. The energy is addictive and the locals genuinely want you to love their city.
