Visitors to the preserve at Mare Island in Vallejo can take in both history and nature.
A trail leads to the top of a 284-foot hill overlooking San Pablo Bay, with distant views of Mount Tamalpais, Mount Diablo and Mount St. Helena. Those who don’t want to hike can still see Mare Island cemetery and century-old stone buildings at the old ammunition depot left over from the island’s long history as a naval shipyard.
Location: Railroad Avenue at southern tip of Mare Island
