What is the best Mexico beach destination for winter sun?

There isn’t a single “best” Mexico beach destination for winter sun—it depends on your style. Cancun and the Riviera Maya are ideal if you want easy access, big resorts, and white‑sand Caribbean beaches. Puerto Vallarta and the Riviera Nayarit offer a more local feel and great Pacific sunsets. Los Cabos combines desert landscapes with upscale resorts and strong winter whale‑watching. For quieter escapes, consider Bacalar’s lagoon, Isla Holbox, or the Oaxaca coast around Puerto Escondido and Mazunte.
