Mission Puerto de Purísima Concepción
Near Winterhaven on the California side of the Colorado River, a state historical landmark marks where Father Francisco Garcés founded a mission-pueblo in October 1780; Quechan and allied tribes destroyed it in July 1781.
Ogilby Hills
The Ogilby Hills are a desert mountain range in Imperial County, California, part of the Colorado Desert in the Lower Colorado River Valley near the Colorado River.
Colorado Desert
Part of the larger Sonoran Desert, the Colorado Desert stretches across Southern California into Baja California. Its low basins are dominated by creosote, ocotillo and cholla cactus, and it meets the Mojave Desert inside Joshua Tree National Park.
Yuha Desert
South of Interstate 8 and west of El Centro, this Sonoran Desert basin holds Yuha Well, the favored water stop of the Anza expeditions of 1774–76. A State Historic Landmark plaque at the eastbound Sunbeam rest area on I-8 near Seeley tells the story.
Desert View Tower
Off I-8 near Jacumba, a four-story stone tower built by Bert Vaughn starting in 1922 now serves as a small museum, and nearby Boulder Park has animals carved into granite boulders during the Depression.
Misión de Nuestra Señora de Guadalupe del Norte
Founded in 1834 by Dominican friar Félix Caballero, the last mission of the colonial-era Californias survives as adobe ruins with an INAH museum in Francisco Zarco, in the heart of the Valle de Guadalupe wine country.
Misión Santo Tomás de Aquino
Dominican missionaries founded Misión Santo Tomás de Aquino in Baja California in 1791 and named it for Saint Thomas Aquinas, in the valley town of Santo Tomás south of Ensenada.
Misión San Vicente Ferrer
San Vicente, about 55 miles south of Ensenada, is the site of a Dominican mission founded in 1780; the town's community museum on the central park displays objects from the mission, Pai Pai artifacts, and mammoth fossils.
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.
