Recently, Georgia Pacific Lumber Company put on the market a piece of property within the city limits, formerly the site of a large mill facility. The mill was shut down in 2002 and has been identified as a nonperforming asset by Georgia Pacific. The mill site takes up almost the entire coastline of Fort Bragg including Soldier Bay. The public of Fort Bragg has embraced the mill site as the future of Fort Bragg and has proposed many forward-thinking ideas. Some possibilities for the mill site are: a marine research center, a conference center, a world-class golf course, a smaller mill, or a branch of a college.
Glass Beach sits on the northern edge of town, along the ocean. In the early 20th century, Fort Bragg residents threw their household trash over these cliffs. They discarded glass, appliances, and even cars. The land was owned at that time by the Union Lumber Company, and locals referred to it as "The Dumps." Sometimes fires would be lit to reduce the size of the trash pile. In 1967, city leaders closed the area and various cleanup programs were undertaken through the years to correct the damage. Over the next several decades the pounding waves cleansed the beach, wearing down the discarded glass into the small, smooth, colored trinkets that coat the beach today. The area is now frequently visited by tourists, who scour the beach for interesting curios to take home as souvenirs. Warning: the path from the road down to the beach is somewhat treacherous, so curious visitors should be sure to wear shoes with good tread. It is not uncommon for unprepared visitors to injure themselves on the way down.
Fort Bragg is the western terminus of the California Western Railroad (otherwise known locally as the "Skunk Train"), running through the Coast Redwood forests to the city of Willits, inland. Started in 1885 as a rail route for moving large logs to the mills, the Skunk Train now offers scenic tours through the redwoods.
The city is also home to the Mendocino Coast Botanical Gardens, a 47 acre garden along the coastal bluffs.
