    Route Description for Thunder Knob Trail

    Thunder Knob Trail is a moderate hike with a calm atmosphere, making it a great choice for family outings or relaxed short trips. The trail is very well-kept and easy to follow, and you can continue to enjoy the lakeshore once you’re done hiking.

    Begin from the trailhead, hiking northwest across the stream to the foot of the knob. The trail gently switchbacks to help you up the elevation gain, which isn’t overwhelming at any point. You’ll get a beautiful view about halfway up, where the trail evens out a bit. Enjoy the view at the top of the knob, then retrace your steps back to the trailhead.
