Dan and I hiked the Sunshine Canyon area on our last day in Boulder. I’ve since learned on trails.com that Mount Sanitas is named for a nearby former sanatorium. If you love to hike in a social setting, this is the trail for you. As we huffed and puffed up the 1255 ft elevation gain, we frequently stopped to let people and their unleashed dogs pass. Once we reached the summit, we were far from alone, but the amazing view was worth it!
