Oregon Caves National Monument, tucked away in the majestic Siskiyou Mountains of Southern Oregon, is a realm of unparalleled natural beauty and historical significance. This 5,400-acre preserve, established in 1909, boasts intricate marble cave systems that stretch over 15,000 feet underground, adorned with glistening stalactites, stalagmites, and other cave formations such as soda straws, cave bacon, and cave curtains.
Above ground, the monument is home to a remnant old-growth coniferous forest, featuring a Douglas-fir tree with the widest known girth in Oregon. Visitors can explore this verdant landscape via six high-elevation hiking trails, each offering panoramic views and a refreshing escape from the summer heat. The trails weave through lush ancient forests, where the sounds of Cave Creek provide a soothing backdrop.
The Oregon Caves Chateau, a historic landmark, stands as a testament to the monument’s rich history and architectural charm. For those looking to delve deeper, guided cave tours, including the Candlelit Cave Tour, offer an immersive experience, where candle lanterns cast dancing shadows on the marble walls.
As the seasons change, the monument transforms; spring brings a flurry of wildflowers, summer offers expansive dark skies perfect for stargazing, and autumn paints the forests in vibrant hues. Local outfitters and nearby artisan towns, such as those in the Illinois Valley, provide ample opportunities for shopping and dining.
