Rainbow Falls

About

Rainbow Falls is a waterfall in Teton County, Wyoming, inside Yellowstone National Park, which is managed by the National Park Service. It sits at about 6,742 feet, and the nearest town is Warm River, Idaho, roughly 22 miles away. Summer is the most comfortable time to visit. Typical averages from a nearby weather station put July highs around 77°F with lows near 38°F, so cool mornings are the norm even in midsummer. One advises visitors to stay away from bull elk, and another notes that no vehicle entrance reservation is needed. The falls sit close to several other destinations. Terraced Falls Trail is under a mile away and Fall River is about a mile off, while Union Falls Trail lies roughly 2.7 miles away and Cave Falls Campground about 6.8 miles away.
