For some reason I find Mount Ascension intimidating. I think it's because there are so many trails intersecting, etc. that it's not easy to map out a route. This is another edge-of-town hike in Helena where the trails are heavily used. This means a lot of trail breakdown that makes using them somewhat unpleasant.
This collection of trails is more commonly referred to as "The South Hill Trails" and are wonderful for morning, lunch break, evening and weekend hikes. They are also great to take visitors from out of town. All these trails loop together and are well marked. Plenty of parking at numerous trail heads. Accessible year-round and well behaved dogs are welcome.
