St. Mary’s is a little secluded alpine community, tucked away about 12 miles northwest of Idaho Springs. The town is limited in facilities, mainly just some permanent home dwellers and seasonal vacation homes.

It’s most known for its beautiful nearby hikes, the most notable being its glacier. St. Mary’s Lake is also a terrific gem located nearby. Much of the land around town is private, so be sure to watch where you park and trek to.

You can reach St. Mary’s by taking Fall River Road, about 10 minutes from exit 238 on I-70, west of Idaho Springs. The paved mountain road takes about thirty minutes. The St. Mary’s CDP was home to 333 people in 2020.
