Snorkeling & Diving in Oaxaca Coast, Mexico
The nine bays of Parque Nacional Huatulco contain some of the healthiest coral reef systems on Mexico's Pacific coast, protected since 1998 from development and fishing pressure that has degraded coastline on either side. The underwater visibility peaks from November through March when the dry season brings calm, clear water and the rainy season river runoff that clouds the bays has stopped. Snorkeling directly from the beach at Bahía Chachacual or Bahía San Agustín puts you above coral formations, schools of parrotfish, sea turtles feeding on seagrass, and the occasional ray moving across the sandy bottom.
Diving the deeper reef structures adds moray eels, giant pufferfish, and on lucky days, whale sharks passing through in winter. The park's no-fishing, no-development status means you're snorkeling a reef that looks like reefs along this coast looked decades ago — intact, colourful, and genuinely worth the hour's drive east from Puerto Escondido.

Know Before You Go
The Zicatela break in Puerto Escondido is nicknamed the Mexican Pipeline for a reason. It is a heavy, fast beach break that has broken bones and held down experienced surfers. If you are not an advanced surfer, watch from the sand or head to Carrizalillo or Playa Mermejita. The current does not negotiate.
From May through October, the humidity on the Oaxaca Coast is not a mild inconvenience — it is a physical presence. Temperatures regularly hit 33°C with 85%+ humidity. Plan outdoor activity before 9am or after 4pm. The hotels are designed for it; the jungle hikes are not.
There is no direct coastal road between Puerto Escondido and Mazunte. Every transfer goes inland on Highway 200, then back down. What looks like 45 minutes on a map is often 90 minutes in a colectivo. Arrange private transfers for anything time-sensitive, and confirm road conditions after heavy rain.
