Huatulco National Park is the reason the bays look the way they do. The state tourism board describes a protected area of more than 11,000 hectares in the municipality of Santa María Huatulco, home to a wide range of land and marine plants and animals, and it covers much of the coast between the resort areas. Its hills sit at the foot of the Sierra Madre del Sur, where the mountains meet the sea, and its habitats include dry tropical forest, mangroves and coral communities. The national protected-areas commission lists trails named Zanate, Cruz del Monte and Sabanal, and notes that visitors can enter daily from early morning until evening. Birdwatchers look for species such as the citreoline trogon, while the shoreline offers snorkelling and quiet beaches that are only reachable by boat or on foot. The park is the common thread of most Huatulco day trips, so even if you never walk a trail you will pass through it on a bays cruise. It rewards slow travel: go early, carry water and enjoy the contrast between the dry forest and the green water.
Why it matters
Huatulco was planned as a resort coast, and the park is what keeps much of the shoreline wild. Instead of a continuous strip of hotels, you get headlands covered in forest, beaches with no buildings and a mangrove edge that shelters birds and fish. The commission notes that the climate is hot and semi-humid, around 28 degrees Celsius, and that the landscape is at its greenest from June to November, after the rains. In the drier months the forest is browner, which makes wildlife easier to spot.
Planning your visit
The park office is in La Crucecita, and the commission page gives daily opening hours and a per-person daily fee, with exemptions for children under 12, seniors and people with disabilities and a discount for students and teachers with a valid card. Confirm the current fee and hours with the office before you go, because they can change. Many visitors never need to pay separately, since boat tours and some day trips cover entry or collect it for you, but ask when you book.
Getting the most from it
Bring a hat, plenty of water and sturdy shoes, because trails are hot and uneven. Go early for birds and for cooler walking, and keep to marked paths to protect the vegetation. Pack out all rubbish and use reef-safe sunscreen, since the coral is fragile. If you want a guide who knows the species, a guided snorkel or a naturalist walk adds a lot, and pairing the park with a bays boat day gives you both the sea view and the forest edge.
