Evans Landing in Farragut State Park is a great place to hike year around. This would be a moderate to hard trail as it’s downhill all the way to the lake and uphill all the way back. Given the 4 mile roundtrip distance and the elevation gain, plan on this hiking taking about 2.5 hours with additional time if you're taking in the views once you reach Evans Landing.
Note: Idaho state parks charge a day-use per vehicle. You can also purchase an annual pass as well.
