Huatulco II

Huatulco II National Park is a marine and coastal protected area on the Pacific coast of Oaxaca, adjacent to the Huatulco National Park established in 1998. The park encompasses additional coastal headlands, bays, and marine waters extending protection along the Bahias de Huatulco resort corridor. The Huatulco coast is remarkable for its geological diversity, with nine major bays separated by rocky headlands, and its tropical dry forest behind pristine beaches. The park's establishment complemented existing protections, creating a more contiguous conservation corridor along one of Mexico's most biologically diverse Pacific coastlines.

The marine ecosystem supports diverse reef fish including hawkfish, parrotfish, and grouper. Pacific sea turtles including olive ridley (Lepidochelys olivacea), leatherback (Dermochelys coriacea), and black sea turtle (Chelonia mydas agassizii) nest on beaches within and adjacent to the park. Spinner dolphins are year-round residents of the bays. Humpback whales visit from December to March. Whale sharks and manta rays occur seasonally offshore. The terrestrial habitat supports collared peccaries, coatimundis, white-tailed deer, and iguanas. Ocelots and jaguarundis are present in the more remote dry forest areas.

The park's terrestrial zone is dominated by tropical dry forest, one of Mexico's most endangered ecosystems, characterized by drought-deciduous trees including copal (Bursera spp.), guamuchil (Pithecellobium dulce), pochote (Ceiba aesculifolia), and various thorny legumes. The dry season strips most trees of their leaves. After the first rains, the forest transforms dramatically with new foliage and flowering. Organ pipe cactus and columnar cacti are conspicuous on rocky headlands. Mangroves fringe estuaries and sheltered bays, providing critical fish nursery habitat.

The Huatulco coast is tectonically active, located where the Cocos Plate subducts beneath the North American Plate—the subduction zone that generates periodic large earthquakes along the Oaxacan coast. The rocky headlands are composed of Precambrian metamorphic and igneous basement rocks, some of the oldest exposed rocks in Mexico dating to over 1 billion years. These ancient rocks create the resistant headlands that divide the coast into distinct bays. The beaches are composed of dark volcanic and metamorphic sands rather than the white carbonate sands of the Caribbean.

The Huatulco coast has a hot, semi-arid tropical climate with a pronounced dry season. Mean annual temperature is 28°C. Annual precipitation averages 800 to 1,000 millimeters, concentrated in the June to October rainy season. The dry season from November to May is sunny and dry—the primary tourist season. Temperatures during the dry season reach 30 to 33°C with low humidity and clear skies. The rainy season brings heavy downpours and occasional Pacific tropical storms. The marine climate is influenced by upwelling along the Oaxacan coast during winter, bringing cooler, nutrient-rich water that increases marine productivity.

The Huatulco coast was inhabited by Zapotec and Chontal peoples for thousands of years, who exploited marine resources and engaged in coastal trade. The Spanish explorer Francisco de Ulloa visited the bays in 1539. The port of Huatulco served as an important Spanish colonial trading post in the 16th century and was sacked by English pirate Francis Drake in 1579. The area remained sparsely populated until the 1980s, when FONATUR began developing the Bahias de Huatulco as a planned resort destination modeled after Cancun.

The original Huatulco National Park was established in 1998 protecting coastal marine and terrestrial habitat adjacent to the resort development. Huatulco II extends protection to additional coastal sections. The park works in coordination with the Huatulco resort master plan, which reserved 70% of the development zone as green space. CONANP manages both Huatulco parks with cooperative agreements with the resort municipality. Sea turtle protection programs on nesting beaches operate throughout the park.

Snorkeling and scuba diving in the clear Pacific waters of the sheltered bays reveal diverse reef fish and, seasonally, manta rays and whale sharks. Kayaking and stand-up paddleboarding explore the bays and sea caves. Hiking trails through tropical dry forest connect several bays and headlands. Sea turtle nesting observation tours operate from June through December on designated nesting beaches. Whale watching boat trips run from December to March. The resort town of La Crucecita provides full tourist services adjacent to the park.

Huatulco has a small international airport with direct flights from Mexico City, Guadalajara, and some US cities. The resort zone and national parks are served by a range of hotels from budget to luxury. Tour operators in Santa Cruz Huatulco offer snorkel, dive, whale-watch, and turtle-watching tours. Park access is integrated with resort activities; most visitors come as part of a Huatulco beach vacation. Park entry fees apply for certain activities and zones. CONANP maintains a visitor center near Santa Cruz Huatulco.

Sea turtle nest protection involves nightly patrols, egg relocation to hatcheries, and public education. Coral reef protection requires enforcement of anchor buoy systems and boat speed limits in sensitive bays. The interface between resort development and natural habitat requires ongoing management of runoff, light pollution, and beach use. Coastal development at the Huatulco resort has been relatively well-managed compared to other Mexican resorts. CONANP works with Huatulco's green certification program and the resort municipality on sustainable tourism standards.
