A little climb. A lot to take in.
What to ExpectThe trees open up. The lake comes into view. Someone reaches for the trail snacks, and everyone finds a reason to pause. Above Idaho Springs, St. Mary’s Glacier brings you into a landscape of alpine water, rocky slopes, and wide Colorado skies. Come ready for a mountain hike, leave time to enjoy the view, and help care for the place that brought you here.
Short trail. Real mountain country.
The roughly 1.5-mile round-trip hike toward the base of St. Mary’s Glacier packs plenty into a short distance. Expect an uphill route over rocks and uneven ground, starting above 10,000 feet. Take your time, catch your breath, and let the slowest person in your group set the pace.
Despite its familiar name, St. Mary’s Glacier is a semi-permanent snowfield. Its size and snow coverage vary with the season and conditions.
The lake makes a rewarding turnaround spot. Continuing toward the snowfield adds more climbing and exposure, and conditions can change what’s comfortable or possible. You don’t have to go farther to make the hike worthwhile.
A little preparation goes a long way.
Bring water, snacks, sun protection, a warm layer, and a rain jacket—even when it feels like summer down in town. Wear sturdy footwear with good traction, download your trail map before arriving, and check the mountain forecast.
Start early enough to leave room for breaks and changing weather. If thunder develops, head back down rather than lingering by the lake or on exposed slopes. Turning around is always part of a good plan.
Snow and ice can make this short hike much more demanding. Stay off lake ice and avoid climbing or sliding on the snowfield without the equipment and skills for the conditions. Winter visits require backcountry preparation and avalanche awareness; traction alone does not make a route safe.
Give this place a little care.
The small choices matter here. Keeping your boots on the trail. Picking up the snack wrapper. Giving someone coming uphill a little room.
Stay on established trails. Avoid shortcuts and stepping onto fragile alpine plants, including when finding a photo spot.
Carry everything back out. That includes food scraps, tissues, and dog-waste bags. If a trash bin is full, take your trash home.
Keep dogs leashed. Bring their water, pick up after them, and carry waste out with you.
Give wildlife space. Watch from a distance and keep food to yourself.
Let the mountain set the soundtrack. Leave speakers behind and make room for creek sounds, wind, and conversation.
Leave the rocks, flowers, and shoreline as you found them. There’s plenty to take home in a photograph.
Be a good neighbor.
Your visit begins in a mountain neighborhood. Park only in designated paid parking areas, follow posted payment instructions, and keep roads and driveways clear. Parking is not allowed along Fall River Road or within the residential subdivision.
If the lots are full, choose another hike and return another time. Please respect private-property signs, keep voices low near homes, and use the restroom facilities at the parking areas before heading up. Camping is not allowed in the Alice and Winterland neighborhoods.
Leave room for something after.
Back in Idaho Springs, trade trail snacks for a meal, wander into a local shop, or settle in for another night in the mountains. The hike might be the reason you came. Leave a little room for whatever becomes your favorite part.
