Day hike into Union Falls with the Sugar 7th Ward High Adventure. It is about a 17 mile hike round trip and you cross the river 4 times each way. The first two crossings you wade right through it, the third crossing there is a downed tree you can cross on and the forth crossing is a log bridge. A very rewarding hike with a beautiful view of Union Falls. Then the real joy is to jump into Ouzel Pool which is bath water warm. The trail from Fish Lake is flat making it a very doable hike for most anyone.
