Take a trip through time in historic Etna. This little Siskiyou County town was founded in the 1870s and still boasts a number of original structures. Book a stay at the Collier Hotel, which was originally built as a brothel for miners but now features well-appointed rooms decorated with period pieces. Denny Bar Co., housed in an old mercantile, uses housemade spirits to put a twist on classic cocktails, while Etna Brewing Co. & Brew Pub occupies a 19th-century bottling plant shut down by prohibition. Etna also serves as an ideal entry point for exploring Klamath National Forest and the Marble Mountain Wilderness. For an unforgettable day, start at the Etna Summit Trailhead and head two miles to Upper Ruffey Lake. Bring a picnic and your swimsuit to spend a few hours on the water before hiking back down.
