Andrews Lake Trail

Overview

Short roadside loop around an alpine lake just off Highway 550 (the Million Dollar Highway) at Molas Pass. Excellent reflections of the surrounding peaks on calm mornings. Connects to the longer Crater Lake Trail for hikers wanting more. The full route covers 1 miles as a loop with about 100 feet of climbing, and most hikers finish it in around 1 hour. It sits in the San Juan Mountains, near Silverton in San Juan County, topping out at 10,760 feet.

Trail Highlights

How Hard Is It?

This is rated easy. The short 1-mile distance paired with gentle 100 feet of gain is what sets the effort level. It runs as a loop, so you get new scenery the whole way and finish back at the trailhead. You spend time above 10,000 feet, so pace yourself and drink more than you think you need. If you hike regularly, plan for roughly 1 hour of moving time; add a buffer for photos, snack stops, and the slower pace at altitude.

Best Time to Hike

The best seasons here are summer and fall. Summer is the reliable window once the snow clears, though that also means the busiest trailheads and the daily afternoon thunderstorm risk. In Colorado the weather turns fast in the high country, so start early, aim to be heading down by early afternoon, and watch the sky. Lightning, not distance, is what turns most summer hikes around.

Getting to the Trailhead

The trailhead is in the San Juan Mountains, closest to Silverton (San Juan County). No pass or permit is required to park, though popular lots still fill early on summer weekends. The parking coordinates are 37.7292, -107.7108; plug those into your map app rather than the trail name, since several Colorado trailheads share names. Mountain weather and road closures can change access, so confirm the access road is open before a long drive.

Dogs & Kids

Dogs are allowed, and they should stay leashed to protect wildlife and other hikers. Kids can handle it with breaks, especially given the 1-mile length. Bring extra snacks and water and let the pace be theirs.

What to Pack

Pack the Colorado basics: more water than you expect, layers for a 30-degree temperature swing, sun protection for the high-altitude UV, and rain protection for the afternoon. For a short, gentle hike like this one, the gear that earns its weight most is comfortable footwear and a solid shell. Here is what we actually recommend for trails like this:

• ›hiking boots with real traction
• ›a packable rain shell
