Chamela Bay: Mexico's Island-Rich Pacific Haven

Chamela Bay holds 11 islands within its 13-kilometer-wide mouth—more than any other bay in Mexico. This protected inlet on Jalisco's Costalegre coast sits about 160 kilometers south of Puerto Vallarta and forms the marine heart of the Chamela-Cuixmala Biosphere Reserve, a UNESCO site since 2006. The bay's calm, turquoise water and white-sand islets make it a base for snorkeling, birdwatching, and simply doing very little.

Getting There and Around

By Car from Puerto Vallarta or Guadalajara

From Puerto Vallarta, take Mexican Federal Highway 200 south for roughly two hours. The road swings inland past Cabo Corrientes before rejoining the coast near Chamela. From Guadalajara, allow about four hours to reach the turnoff for Punta Pérula, the main access village on the bay. The final stretch is well signed, though some beach turnoffs are easy to miss—watch for the small blue signs for La Huerta.

By Bus

First-class buses (ETN and others) run from Puerto Vallarta and Guadalajara to Cihuatlán or Barra de Navidad, where you can catch a local second-class bus or taxi to Punta Pérula. The trip from Guadalajara to the coast takes five to six hours; from Puerto Vallarta, about three. Fares from Guadalajara to Barra de Navidad run between 380 and 500 pesos.

Local Transport and Boat Trips

Punta Pérula's malecón (pier) is the departure point for pangas (small motorboats) to the islands. A round-trip to Isla Cocinas takes 20 to 25 minutes each way and costs around 500 pesos per person, though prices vary by season and group size—confirm before boarding. No ferries serve the islands; all access is by chartered boat.

What to See and Do

Island Hopping: Isla Cocinas and Isla Pajarera

Isla Cocinas is the most visited island—a 4-kilometer run from Punta Pérula—with a crescent of white sand and water clear enough for snorkeling right off the beach. It has no facilities, so bring water and shade. Isla Pajarera, a few minutes farther, is a nesting colony for thousands of blue-footed boobies and magnificent frigatebirds. Boats keep a respectful distance; you will not land here. Between February and March, migratory seabirds swell the populations dramatically.

Snorkeling, Kayaking, and Paddleboarding

The bay's sheltered water makes it easy for beginners. Snorkelers can expect to see colorful reef fish, but visibility is best from November to April when seas are calm. Kayak and paddleboard rentals are available in Punta Pérula; a half-day guided tour typically includes equipment and a stop at one of the quieter islands. No permit is required for personal kayaks, but tour operators must be authorized by the reserve.

Birdwatching and Wildlife

The Chamela-Cuixmala Biosphere Reserve protects 270 bird species, 72 mammals, and 46 reptiles—including jaguars and pumas in the dry forest above the coast. The islands themselves host brown pelicans, terns, and frigatebirds. A pair of binoculars is essential; early morning is the most active time. The reserve's research station (Estación de Biología Chamela, run by UNAM) is not open to casual visitors, but the surrounding trails can be explored with a local guide.

Beaches and Sunsets

Playa Chamela, the main beach facing open ocean, stretches for kilometers and is rarely crowded. Punta Pérula's beach is calmer, with gentle waves ideal for swimming. Stay for sunset—the bay faces west, and the silhouettes of the islands turn black against orange water. Bring mosquito repellent for the evening; the mangroves behind the beach breed them.

When to Visit and What to Know

Best Season: November to May

The dry season brings clear skies, calm seas, and reliable boat trips. Temperatures average 28°C (82°F) year-round, but humidity is lower from November to May. June to October is the wet season: heavy afternoon rains, choppy water, and many tour operators close. If you visit in the wet season, plan activities for the morning and expect lush green hills—but also leeches on jungle trails.

Whale Watching and Turtle Nesting

Humpback whales pass offshore from November to March; some boats from Punta Pérula offer whale-watching trips (around 800 pesos per person for three hours). Sea turtles—mainly olive ridley—nest on the reserve's beaches from June to December, with peak nesting in September and October. The reserve's Cuixmala and Teopa beaches are designated turtle sanctuaries; night tours to see nesting turtles are sometimes available through local guides, but never touch or disturb the animals.

Practical Essentials

There is no entrance fee for Chamela Bay itself, but the islands are part of a federal sanctuary, and tour operators pay a concession. Fees are subject to change—check with CONANP (the National Commission of Protected Natural Areas) for current regulations. Bring cash: ATMs are scarce in Punta Pérula, and most boat captains do not accept cards. Cell signal is patchy on the islands. Pack out all trash; the reserve has no waste collection on the islets.

Frequently Asked Questions

How long does it take to visit Chamela Bay?

Most visitors spend two to three days in the area. A half-day boat trip to Isla Cocinas covers the highlights; add another day for kayaking and a third for birdwatching or a trip to the reserve's dry forest. Day-trippers from Puerto Vallarta face a four-hour round-trip drive, so staying overnight in Punta Pérula is more practical.

Do I need a permit to visit the islands?

No permit is required for individual visitors arriving by chartered boat, but your boat operator must hold a valid concession from CONANP. Independent kayakers should check in with the reserve office in Punta Pérula before launching. Fishing is prohibited without a separate license.

What is the best time for snorkeling?

Visibility peaks from November to April, when the water is calm and rainfall runoff is minimal. Water temperature stays around 24–26°C (75–79°F), so a 3mm wetsuit is comfortable for longer sessions. After heavy rain in September, runoff can reduce visibility for several days.

Are there restaurants or shops on the islands?

None. Isla Cocinas and the other islands are undeveloped. Bring all food, water, and sunscreen from Punta Pérula. The village has a handful of small seafood restaurants (marisquerías) that serve fresh fish and shrimp for around 150–250 pesos per plate.
