    Located within the grounds of John Muir National Historic Site, the Vicente Martínez adobe provides interpretation of the passage of the Anza expedition and the subsequent Spanish and Mexican periods. The wife of Vicente Martínez was Guadalupe Moraga, a great-granddaughter of the San Francisco founder. While in Concord, one can visit the Salvio Pacheco Adobe (1870 Adobe St.) or the Don Fernando Pacheco Adobe (3119 Grant St. within Hillcrest Park).

Fernando was their son.
  • Rodeo - Expedition Camp #99
    Anza's men chased Tule Elk (Cervus elaphus nannodes) near Berkeley, and then continued north. On April 1st, the group camped at a small stream. Today, the campsite is at the conjunction of Parker and San Pablo Avenues and Rodeo Creek, a heavily industrialized area. A commemorative marker from the 1976 reenactment is on Parker Road between 4th and 6th Street in front of the post office in the town of Rodeo.

An interpretive stop located on the eastern side of Willow Pass describes the Puerto Dulce. EBRPD manages hundreds of miles of trails including the Skyline National Recreation Trail. This trail, and the Bay Area Ridge Trail parallel Anza's route, although at a higher elevation so that they offer panoramic views of San Francisco Bay. At both the Carquinez Strait and Antioch / Oakley Regional Shoreline parks give a closer view. At the latter, Camp #101 is commemorated with a plaque placed on the edge of the shore on the east side of the fishing pier.

    West of the Carquinez Bridge, their hillside vantage point can be reached via San Pablo Ave. through the East Bay Regional Park District's (EBRPD) Selby Open Space area across from Vista del Rio Road. A short, but steep, hike from the parking area takes you to the viewpoint. On April 2, 1776, Father Font notes, "…This Puerto Dulce [sweet harbor], indeed, is a gulf of fresh water, enclosed in a canyon by hills...In the bay and in front of the mouth there is an island [Mare Island]…" The location of the hill is close to 38º 03' 14" N, 122º 14' 37" W.
