Box Canyon has been my favorite nearby destination since I moved here. I love the hike down the canyon and the trail that runs near the waterfall in Box Canyon.
Sometimes the thing that makes a waterfall attraction so attractive isn't the size but the adventure to get there or the ability to interact with the waterfall.
During the winter there are massive icicles, or the kids called them frozen waterfalls, all along the wall. The ice is beautiful and extremely dangerous.
