Ex explosive factory and possibly World War II military post turned to amazing park
Pt Pinole Regional Shoreline Park was the site of a number of explosive factories. The Pt Pinole factory was operated until 1960. Eventually the property was purchased by the East Bay Regional Parks in 1973. There are some remnants of the dynamite factory including the trails we will walk. Note that the large groves of eucalyptus were planted to buffer against potential explosions.
Dotson Family Marsh (formerly Breuner Marsh) was fought over from the 1970’s to keep it from being developed. East Bay Regional Parks purchased a large portion of the marsh in 2011 for about $8.8 million. It was renamed in 2017 Dotson Family Marsh after a local family that fought to keep it from being developed.
FACILITIES: There are restrooms at the trailhead and approximately one hour into the hike as well as in several locations along the trail. Water is available at the trailhead and midway by the pier.
