Quiet Baja town, big Sea of Cortez wildlife, and island diving inside a national park
Currently Viewing:
Overview
Loreto is Baja California Sur at its most relaxed: a walkable mission town on the Sea of Cortez with protected islands right offshore. Most diving and snorkeling happens by small boat (panga) inside Parque Nacional Bahia de Loreto, where volcanic islands create rocky reefs, pinnacles, and sea lion hangouts. Add winter whale season (blue whales are the headline), warm-water summer snorkeling, and uncrowded topside days in the Sierra de la Giganta, and you have a rare mix of wilderness and comfort.
Plan on boat diving rather than shore entries, carry your national park conservation bracelet, and build flexibility into the schedule for wind. Non-divers have an equally strong itinerary: island beach days, kayaking, golf at Danzante Bay, and day trips to Mission San Javier and the turquoise coves of Bahia Concepcion.
Loreto diving is "Sea of Cortez style": volcanic rock, bait balls, and charismatic megafauna rather than coral gardens. Most sites sit around the offshore islands, with typical profiles from 6 m to 30 m and visibility often 10 m to 25 m depending on season and plankton.
Use these as the backbone for your week (all inside or adjacent to Loreto Bay National Park):
Loreto's islands are a federally protected area. Expect operators to require the park bracelet and to brief "leave no trace" behavior:
Loreto is also a great hub for road-tripping Baja Sur:

Trip callouts
Dive and snorkel the islands of Parque Nacional Bahia de Loreto, with fees supporting protected-area management.
Winter brings a strong chance of seeing blue whales and other cetaceans on dedicated boat trips.
Shallow sites around Isla Coronados can deliver memorable, high-energy interactions with sea lions (conditions and behavior dependent).
Many dives are calm, boat-supported, and shallow enough for newer divers, with deeper pinnacles available when you want to level up.
Pair island days with historic missions, Sierra de la Giganta hikes, and low-key dining in a walkable town.
scuba
Why Loreto for Scuba Diving
Loreto is a boat-diving destination built around the islands of Parque Nacional Bahia de Loreto. Local operators like Dolphin Dive Center Loreto and Blue Nation run small-group panga trips to volcanic reefs, pinnacles, and sea lion sites, with the bonus of winter whale watching on the same waters. Expect a mix of relaxed, shallow dives and more dynamic days on seamounts when currents and wind cooperate.
freedive
Why Loreto for Freediving
Loreto gives freedivers access to deep water close to shore, with boat support from local captains and dive operators who know the park islands. When seas are calm, the channels around Isla Carmen and Isla Danzante can be excellent for line training, while shallow coves around Isla Coronados keep non-divers and photographers happy.
snorkel
Why Loreto for Snorkeling
Loreto is one of the easiest ways to get island snorkeling in the Sea of Cortez. Day boats from Loreto Marina reach protected beaches and coves inside Loreto Bay National Park, where volcanic rock reefs attract colorful reef fish and occasional bigger visitors. Isla Coronados is the signature day trip for clear water, beach time, and (when appropriate) sea lion viewing.

What to do when you're not in the water
Loreto is compact enough to feel easy, but wild enough to keep you busy for a week. Walk the historic center and the mission, day-trip into the Sierra de la Giganta to Mission San Javier, book a sunset sail, or play a round at Danzante Bay. If you have a rental car, Loreto is also a perfect midpoint for a northbound beach run to Mulege and Bahia Concepcion or a southbound push to La Paz.
