Rewards come quickly at Tumalo Falls: views of the eponymous 97-foot gusher lie just a five-minute walk from the parking lot. Once you’re sufficiently wowed, pick up the North Fork Trail and hike upstream on a gently uphill meander that leads to several smaller waterfalls. Turn around at your leisure—but those up for a longer trek will be rewarded after four miles with the sight of Happy Valley, an appropriately named alpine meadow popping with lupine, larkspur, and Indian paintbrush, with wooden bridges spanning gurgling creeks.
