From Lander you will drive up Sinks Canyon past Bruce's Bridge and up the switchbacks. You will pass Frye Lake before seeing the right hand turn into Worthen Meadows. The road turns to dirt just after this turn off. Worthen offers two trail head options. As you pull into the trail head parking lot Worthen Resevoir will be behind you. To your left you see Stough Creek trail head and Sheep's Bridge trail head will be off to your right. This area has a plethora of options from a short day hike to Roaring Fork Lake (very kid friendly), several long to longer loop options as well as a great jumping off point to get deeper into the Wind River Mountains for some overnight options. Sheep's Bridge trail gains elevation for about the first mile and then drops steeply down towards the Middle Fork of the Popo Agie River over the next couple of miles. There are a couple of creek crossings but pretty dry otherwise. Some folks like to park a vehicle at Bruce's Bridge and then hike from Worthen one way down to Bruce's this is about 8 miles and you will need to shuttle a vehicle.
