When you get to San Quintín
On Baja California's Pacific coast, roughly three hours south of Ensenada on Highway 1, San Quintín spreads across a farming valley beside a sheltered bay ringed by extinct volcanic cones. The area is known for sport fishing, oyster and abalone farms, and coastal wetlands where thousands of brant geese from Alaska and Canada spend the winter.
- Oyster farms: Shellfish farms in the bay raise several species, and you can visit the oyster growers and taste the catch right where it comes out of the water. source
- Volcanic cones: Extinct basaltic volcanoes such as Monte Ceniza, Punta Mazo and Riverol rise above the coastline and frame the bay. source
- San Quintín wetlands: The bay's wetlands shelter migratory birds and marine life, and in winter they host thousands of brant geese that fly down from Alaska and Canada. source

How we put this guide together
Wayro calculates the route from OpenStreetMap road data; mile numbers are positions along this route, not highway mile markers, and "from the route" distances are straight-line, so the real detour depends on access roads. Stops are chosen from parks, natural sites, museums, historic sites and attractions close to the route (roughly 2 to 7 miles depending on the type, farther for World Heritage sites): at least one strong stop for each stretch of the drive, then the best-known places nearest the road, with no more than five of one type, up to nine in all. Places that are closed, private or not open to visitors are removed. Place and city descriptions are written by the Wayro team from official park, museum, tourism and government websites and other published sources. Safety levels and entry rules were checked against the U.S. Department of State on September 29, 2026. Conditions change, so check the linked sources before you travel.
