Day 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 beautiful view of Union Falls then the real jou 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.
