The five islands of Loreto National Marine Park — Isla Carmen, Coronados, Danzante, Monserrat, and Santa Catalina — lie just offshore from Loreto and offer some of the best snorkeling, kayaking, and sport fishing in the Sea of Cortez. Full-day and half-day panga excursions depart from Loreto's waterfront daily. Isla Carmen has a sea kayaking circuit and salt flats inside a volcanic caldera. Isla Coronados has a striking volcanic cone. Santa Catalina is home to endemic rattleless rattlesnakes found nowhere else on Earth.
Parque Nacional Bahía de Loreto covers roughly 2,000 square kilometres of the Sea of Cortez directly offshore from Loreto, in northern Baja California Sur, taking in five islands: Coronados, Carmen, Danzante, Monserrat and Santa Catalina. Boats leave from the Loreto waterfront and the marina at Puerto Escondido, with the nearest island only 15 minutes away and Santa Catalina closer to two hours, so the choice of island effectively sets the length of the day. Panga excursions with local operators such as Las Paredes Diving, Loreto Bay Outfitters and Arturo's Sport Fishing run about USD 60-100 per person, with the national park fee of roughly USD 10-15 collected separately at the port office.
Isla Coronados is the standard half-day destination — an extinct volcanic cone rising above a curve of white sand, with a small sea lion haul-out and easy snorkelling in clear shallow water. Isla Danzante, a long ridge of eroded rock, has some of the better reef snorkelling and cliff-nesting seabird colonies. Isla Carmen is the largest, with a sea kayaking circuit around its shore, an abandoned salt works at Bahía Salinas and a herd of reintroduced desert bighorn sheep. Santa Catalina, furthest out, holds species found nowhere else, including a rattlesnake that has lost its rattle and a giant barrel cactus. The waters between them hold blue and fin whales in winter, bottlenose dolphins year-round, and yellowtail and cabrilla for sport fishers.
A full-day trip usually leaves the waterfront around 7AM to use the calm morning water, snorkels an island reef mid-morning, lands on a beach for a picnic, and spends the afternoon paddling or fishing before returning by 4PM. There are no restaurants, drinking water or shade structures on the islands, and camping requires a separate permit, so lunch, water and sun protection all travel in on the boat.
The park was declared in 1996 and forms part of the UNESCO-listed Gulf of California site; fishing rules, landing points and visitor numbers are regulated, which is why booking through a licensed Loreto operator matters rather than arranging passage informally at the beach.

When to visit
October through May brings calm seas, clear water and comfortable temperatures, with whale sightings most likely from January to March. Departures around 7AM take advantage of the flattest water, since the afternoon coromuel wind often builds a chop that cuts trips short.
Accessibility
Boarding a panga from the Loreto waterfront involves a step down into an open boat, and island landings are wet, onto sand with no dock, so the excursion is impractical for wheelchair users and difficult for anyone with significant mobility limitations. Larger vessels from Puerto Escondido offer easier boarding and shaded seating and can be requested when booking.
Frequently asked questions
Which island suits a short trip from Loreto?
Isla Coronados is the usual choice for a half-day, roughly 15-20 minutes out by panga, with a sheltered white-sand beach, easy snorkelling and a sea lion haul-out. Santa Catalina is a two-hour crossing and needs a full day.
How much does a boat trip into the marine park cost?
Panga excursions with Loreto operators run about USD 60-100 per person depending on the island and duration, usually including guide and snorkel gear. The national park entry fee of roughly USD 10-15 is charged separately at the port office.
Are there facilities on the islands?
Essentially none. The islands have no restaurants, drinking water, shade structures or reliable restrooms, and camping requires a permit obtained in advance. Visitors need to bring a packed lunch, plenty of water and full sun protection.
Is it possible to see whales in Loreto Bay?
Yes. Blue and fin whales move through the channel between roughly January and March, and bottlenose dolphins are present year-round. Whale watching is regulated, with minimum approach distances that licensed operators are required to observe.
