This is a the route from Iron Creek to Sawtooth Lake.
This is a great day hike or can be made into a backpacking adventure. The trail is relatively easy and short to Alpine Lake and Sawtooth Lake. We stayed at Alpine Lake the first trip and Sawtooth Lake the second. We enjoyed camping at Alpine more, which offered more privacy on the backside of the lake. Both lakes are beautiful and the view of the Sawtooth ridges from Sawtooth Lake is a one of a kind. You can make this into a multi-day trip if you go past Sawtooth Lake where the trail splits. I would recommend this trail as a must.
