A young friend of the family and I decided to take a day hike and explore a route to the top of Hall Mtn. which is due east of Sullivan Lake. If walking, the hike can be shortened to just the single track portion during the timeframe between November 30th and August 15th whereby vehicle access is allowed to the trailhead. Between August 15th and November 30th a Forest Service gate is closed for the benefit of wildlife habitat and extends the journey on foot approximately 3.5 miles, one way, up a service access rd. The entire route is able to be ridden on an MTB although the cyclist needs to be experienced and fit. The bike route, (to & from), can be extended to 18 miles or more depending on the desire of the rider(s). All that being said, this is one of the most beautiful places I've ever been. The only way to the very top is via a single track trail which is approximately 3 miles one way. The views are spectacular and the journey instills a real sense of experiencing nature. I've had a desire to travel to this mountain top for nearly 40 years and finally did so. I'll go back many times. Enjoy the photos!
