Cave Junction's main point of interest is the Oregon Caves National Monument and Preserve, which is a 4554acre area of hiking trails and caverns. Located at the end of a 20mi "stomach churning" drive along State Route 46, there are limestone caves discovered in 1874 by a hunter and his dog. At the caves, there is a 23-room chateau that was built in 1932.
Each year Cave Junction features an ArtWalk on the second Friday of each month, except during the winter, with the city's businesses exhibiting various types of art such as pottery, iron art, music and fire dancing. The ArtWalk adds significantly to the Illinois Valley's positive image and increases tourism and adds to the local economy. According to surveys conducted in 2006 by the Arts Council of Southern Oregon, the city sees a 30–50 percent increase in sales and visitors during the event. Attendance is approximately 150–200 people, with roughly 15 percent coming from outside the community. Local artists, including students of Lorna Byrne Middle School in 2007, participate while local businesses, including thrift stores and art galleries, serve as hosts.
Located about 10mi southeast of Cave Junction, in Takilma, Oregon, is the home of the Out'n'About Treehouse Treesort, a multi-treehouse resort run by Michael Garnier using Garnier limbs. Garnier developed the Garnier limb, which is a one-and-a-half-inch-thick bolt surrounded by a cuff, both made of Grade 5 steel, and is able to support 8000lb. As of 2007, the treesort has nine treehouses, three with bathrooms. Garnier had to fight local government ordinances for almost ten years before gaining the right to house guests in his nine treehouses.
Great Cats World Park is located a few miles south of Cave Junction. As of 2007, it has 32 cats, of 17 different species, including cougars, leopards, jaguars, lions, Siberian tiger cubs, a fishing cat, and an ocelot. Other attractions include the It's a Burl handcrafted wood gallery and the Kerbyville Museum, both in Kerby. Cave Junction's Wild River Brewery serves one of the smallest communities of any Oregon brewery. Founded in 1975 as the Pizza Deli, a microbrewery was added in 1989. In 1994, the name Wild River was adopted and a Wild River restaurant and pub was opened in Grants Pass.
