The sister had a friend who couldn't use her reserved nights here this weekend, so we broke out the trailer and had a great time. We couldn't have asked for better weather, but the foghorn was loud at night. Anyway, in honor of the fun we had, we strolled out and placed a cache.
Doran Regional Park features a wide, 2-mile stretch of beach on Bodega Bay and is ideal for walking, picnicking, playing in the sand, flying kites, surfing, and bird-watching. It covers an area of 127 acres (51 ha).
A recently renovated boat launch provides access to Bodega Harbor and Bodega Bay for sport fishing, kayaking, stand-up paddling, and kite surfing. A rock jetty on the west end of the park is a popular spot for fishing and exploring sea life.
Doran Regional Park has more than 120 pet friendly campsites for tents, trailers and RVs that feature potable water, fire rings, picnic tables, and full-service restrooms with showers nearby. The Shell, Gull and Cove campgrounds are bordered by the Bodega Harbor and the Jetty campground is between the harbor and the beach.
Doran Regional Park was once part of a ranch owned by William (Billy) Doran, who lived on a low hill just above the outer bay and south of the park. During World War II, the government took control of the bay portion of Doran Ranch through eminent domain to create a safe harbor for rescue operations and constructed the jetties at the mouth of the harbor with locally quarried rock. After the war, the land eventually passed to the County and the beach was established as a formal park in the late 1960s. The Coast Guard Station Bodega Bay is located within the boundaries of the park.
You can hike in, or pay the $7 entrance fee. Better yet, think about purchasing an annual pass which works in all of the 50+ amazing regional parks.
