There is roadside parking here along Steuart Road, a gravel trail that leads up to Loch Lomond. You can drive to the top and park right along the lake, or park down here and run up the gravel road. In the winter when the upper lot is closed, this is where you start the trail.

There is a large gravel lot here right on the shore of Loch Lomond which provides access to the the trails around the numerous alpine lakes in the area. You can also access James Peak via a connector from the Upper Lakes trail. If your vehicle can't make it up the gravel road you can always park at the bottom and run up.

Loch Lomond is a mountain lake in the high forests of Colorado. There are actually several lakes in the area, and they are all interconnected, with Loch Lomond being the lowest and the largest. The area is open to cars, bikers, and hikers so you can plan for crowds during the warmer months.

Fed by the snowmelt of Saint Mary's Glacier, this alpine lake is set in stunning scenery just half a mile from the parking area. The beginning of the trail is often heavily trafficked with hikers and other runners, but the further you continue past the lake, the quieter the trail becomes.

Saint Mary's Glacier actually isn't a glacier at all; it's simply a snowfield that doesn't completely melt in the warmer months. The persistence of snow throughout the year caused people to start referring to the snow mass as a glacier, but it isn't actually moving down the valley (which is the distinguishing feature of a glacier). This is still a cool feature to come check out any time of year.

Saint Mary's Lake is fed by the melting Saint Mary's Glacier. There is a paid parking area below the lake with restrooms and informational signs. The hike up to the lake is extremely popular, but the further you push past the lake, the fewer people you will encounter.
