Quick Info
Distance: 7.4 miles round-trip to Ice Lake. Elevation gain: 2,500 feet. Difficulty: Strenuous. Best time: July-September. Trailhead: South Mineral Campground. Dogs: Allowed on leash.
Ice Lakes Trail is one of Colorado's most spectacular hikes. The destination—a vivid turquoise alpine lake ringed by 13,000-foot peaks—is worth every step of the challenging climb. The color comes from glacial flour suspended in the water, creating that iconic Caribbean-meets-alpine appearance.
The trail is popular for good reason, but the effort required keeps it from being overrun. Plan for a full day, start early, and prepare for the altitude. The payoff is unforgettable.
The Trail
Lower Ice Lake Basin: The first 3 miles climb steadily through forest, then emerge into the lower basin. Wildflowers explode here in July and early August. This section alone rewards hikers who can't complete the full route.
Upper climb: From the lower basin, the trail steepens for the final push to Ice Lake at 12,585 feet. Switchbacks help, but this section is relentless. Take your time—the altitude makes everything harder.
Ice Lake: The main attraction. A deep turquoise lake surrounded by rocky peaks. Fuller Lake sits just above for those with energy to explore further. Island Lake requires additional hiking but extends the adventure.
When to Go
July-August: Peak season. Wildflowers bloom, snow has melted from the trail, and conditions are most reliable. Also the most crowded period.
Early September: Fewer crowds, but weather becomes less predictable. Fall color can begin. Risk of early snow increases.
June: Snow often lingers into late June. Trail may be partially buried. Experienced hikers only.
Time of day: Start by 6am to avoid afternoon thunderstorms and secure trailhead parking. By 8am on summer weekends, parking fills completely.
Difficulty Assessment
Elevation: Starting at 9,840 feet, topping out at 12,585 feet. You'll feel the altitude, especially if you're from sea level.
Steepness: The final mile gains over 1,000 feet. The grade is challenging but well-maintained with switchbacks.
Fitness required: You should be comfortable hiking 7+ miles with significant elevation gain. This isn't a beginner trail.
Time estimate: 5-7 hours round trip for fit hikers. Allow more time if you're not acclimatized or want to linger at the lake.
What to Bring
Water: At least 3 liters. There's no reliable water source until the upper basin, and you'll sweat on the climb.
Layers: Weather changes rapidly above treeline. Bring a rain jacket and warm layer even if the morning is clear.
Sun protection: No shade above treeline. Sunscreen, hat, and sunglasses are essential.
Food: Pack more than you think you need. A lunch at the lake is part of the experience.
Trekking poles: Helpful on the steep sections, especially for the descent.
Tips
Arrive early for parking. The trailhead lot fills by 8am on summer weekends. No overflow parking nearby.
Stay overnight in Silverton. The drive from Durango adds time. Being close means you can start earlier.
Acclimate first. If you arrived in Colorado yesterday, this hike will crush you. Spend a day at altitude before attempting it.
Watch the weather. Thunderstorms build daily in summer. Plan to be descending from the lake by noon.
Don't skip the lower basin. Even if you can't make the lake, the lower basin rewards with waterfalls and wildflowers.
Frequently Asked Questions
Can I swim in Ice Lake?
You can, but it's cold—very cold. The water barely warms above freezing even in August. Quick dips happen; extended swimming doesn't.
Is the trail crowded?
On summer weekends, yes. Start early to beat crowds and have more solitude at the lake. Weekdays are significantly quieter.
Can I camp at Ice Lake?
Backcountry camping is allowed with proper Leave No Trace practices. Permits aren't required, but regulations apply—check current rules.
How do I get to the trailhead?
From Silverton, head west on Highway 110 toward South Mineral Campground. The trailhead is at the campground. Passenger cars can make it on the dirt road.
Is it worth it?
Absolutely. Ice Lake ranks among Colorado's most beautiful hikes. The effort is real but the reward is extraordinary.
