Tips from the Community

Sue
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.

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.

Thumbs up, you made it to the top of Mount Ascension! This is the spot to take a rest and refuel for the fun part is it's (almost) all downhill from here.
