September 9, 2025, Helena

As the state capitol and county seat there is a lot going on in Helena. When you add in the historic buildings, dating back to the gold rush days, and the stunning natural scenery you're bound to love this town. It has everything to be a destination of its own, but if you're passing through on the Great Divide Mountain Bike Route you'll leave town with everything you need to keep you going.

This trail is a true local's favorite for hiking and biking, but there may be safety in numbers as grizzly bear are known to be in the area.

February 5, 2024, Lime Kiln Ruins

These ruins near Helena are a beautiful testament to the area's rich industrial history. Despite appearing like mining smelters, these kilns produced quicklime from the local limestone before the 20th century. They have been designated as meaningful cultural heritage sites and are listed on the National Register of Historic Places. The city's impressive historic architecture owes much to the early lime industry, and although the kilns may seem sturdy, they are very fragile, so do not climb on or inside them. However, you can always take a moment to appreciate the ruins and capture some great photos.

Mount Ascension is just outside of Helena and gives a nice view of the surrounding natural areas as well as the city. It is a well-maintained trail and open year-round, but in the winter, watch out for ice in the shady areas.

November 5, 2023, Mansion District

The Mansion District's West Residential section, nestled on the lower slopes of Mount Helena just west of downtown, is a charming area. Its tree-lined streets and stone walls evoke the late 19th century, with many homes from that era still standing. The district boasts a range of architectural styles, and among the notable mansions are those that once belonged to influential figures like Senator Thomas C. Power, B. H. Tatum, D. A. G. Floweree, and S. T. Hauser. Strolling through this historic neighborhood is like stepping back in time.

Little Moab gives you a taste of the famous Slickrock from the namesake Utah town. The trails isn't marked across the rock face as there are several rideable lines. Take your pick or do some laps to try them all.

From the North side of Mount Helena you have excellent views over the Capital City. However, once you make the turn and get behind the mountain the views open up to the spectacular surroundings and invite you to explore some more.
