You're probably thinking of Grotto Falls. The hike from the Hyalite trailhead to Hyalite Peak is a neat one. Lots of neat waterfalls, and the view from Hyalite Peak (10k ft plus) is amazing.It's also a neat hike to go from the Fairy Lake trail in the Bridgers and hit the summit of Sacajawea Peak.
Grab a steak at The Land of Magic in Logan. Best steak you will ever eat. We ate the 3 times in 7 days when I was back there last summer. Oh ya, Cold Smoke beer on tap. Yummmm
