Most hikers heading into Wildcat Canyon Regional Park near Richmond, California, come for the ridge-top views, wandering cattle and groves of coast live oak and eucalyptus. Few realise that scattered among the hillsides sit the crumbling foundations of a sprawling health resort that once treated some of the Bay Area's sickest patients.
The Grand Vista Sanitarium — often called the Belgum Sanitarium — was founded in 1914 by Dr Hendrick Nelsen Belgum, who believed healing required fresh air, good food and beautiful surroundings. His estate covered it all: fruit orchards, vegetable gardens, plant conservatories, palm groves, a spring water system built for patients, plus fresh dairy and poultry on site. One of his brochures praised the abundance of "fresh, wholesome, nourishing foods" as essential to restoring health. Local opinion was split over the years — some neighbours bluntly called it "the crazy house", while others remembered a stunning estate with immaculate gardens and quiet, harmless patients who were a familiar part of the community.
Belgum ran the place with real devotion until 1948, when he died of a heart attack after battling a brush fire threatening the property. His siblings carried on, but without his medical leadership the sanitarium faded. When his brother died in 1963 with no heirs, the estate was abandoned and left to the elements. In 1977, arsonists burned the mansion down for good.
Today the site is a genuinely unusual hiking destination. Out-of-place palm trees, pockets of old plantings, foundation ruins and an interpretive placard are all that remain — and they sit directly on the Belgum Trail Loop, near the Bonitas Gate trailhead. Combine the history stop with the park's wider appeal: roughly 24 miles of trails in the East Bay hills, sweeping Bay views and grazing cows along the ridgelines.
For travellers, this is the kind of offbeat stop that makes a Bay Area hiking day memorable. It's free, easy to reach from Oakland or Berkeley, and pairs well with a broader East Bay regional parks itinerary. Anyone interested in early 20th-century alternative medicine, California eccentric history or just a hike with a story attached will find it worth the detour.
