A High-Altitude Jewel in Colorado's San Juan Mountains
Tucked deep within the San Juan Mountains near Silverton, Colorado, this basin is one of the most breathtaking alpine destinations in the American Southwest. This remote wilderness area is known for its vibrant turquoise-blue lakes, jagged 13,000-foot peaks, and lush wildflower meadows that explode with color in the summer months. But don’t let the beauty fool you—this hike is not for the faint of heart.
🥾 About the Hike: Ice Lake and Island Lake Loop
This trail takes you through some of the most stunning alpine terrain in the state, but it is very strenuous and suited only for experienced hikers and acclimated visitors. The route is roughly 7.2 miles round trip with over 2,600 feet of elevation gain, topping out at around 12,600 feet above sea level.
Start at Ice Lake Trailhead just off County Road 7, about 15 minutes from Silverton.
First destination: Ice Lake. The electric blue water will blow your mind.
From there, head up and over a short saddle to Island Lake—arguably just as stunning, with its deep blue water and unique rock formations.
💡 Tip: Hike to Ice Lake first, then continue to Island Lake before heading back down. It’s a loop option that gives you the best views and a bit less backtracking.
⚠️ This Is a Difficult, High-Altitude Trail
Make no mistake—this is a very hard hike. The elevation gain is steep and sustained, and the altitude can seriously affect unacclimated hikers. You’ll be hiking well above 12,000 feet, so take it slow and consider bringing canned oxygen or electrolyte supplements to help combat altitude sickness. Many hikers report headaches, nausea, and shortness of breath on this trail—even if they're in great shape.
🐾 Is It Pet Friendly?
Yes, leashed dogs are allowed, but please read this carefully:
Only bring seasoned hiking dogs—this is not a trail for casual walks or small, older, or flat-faced breeds.
There are rocky scrambles, steep drop-offs, and some areas with snowfields, even in summer.
The altitude can also affect dogs. Bring extra water for them and don’t push them too hard.
Please pack out ALL WASTE. This is a delicate alpine environment.
🌩️ Weather: Beautiful but Brutal
One of the most critical things to know about Ice Lake Basin is that the weather can change in an instant.
Even if the forecast says "partly cloudy," you could be hit by a lightning storm within minutes once you’re above tree line.
Storms build quickly in the San Juans, especially in the summer. Start your hike early—ideally before 6 AM—and aim to be descending by early afternoon.
Bring:
Warm layers
Waterproof jacket
Hat and gloves
Extra socks
Trekking poles (especially helpful on the descent)
⚠️ Don't underestimate the cold. It can snow—even in July.
🧭 Getting There: Road Navigation Tips
From Silverton, take Highway 550 north for about 2 miles.
Turn left onto County Road 7 (South Mineral Creek Road)—it’s a well-graded dirt road suitable for most vehicles.
Continue for about 4.3 miles to reach the Ice Lake Trailhead parking area.
The lot fills up early (by 6–7 AM in summer), so plan to arrive early or be prepared to park along the road.
🏕️ Camping & Lodging
Dispersed camping is available along South Mineral Creek Road, and it’s one of the most scenic places to camp in Colorado. These are first-come, first-served sites—rustic but free.
There is no water or toilets at most sites, so pack accordingly.
Bear activity is possible—store food properly.
If you prefer a roof over your head:
Silverton offers small inns, B&Bs, and rustic lodges about 15 minutes away.
🐿️ Wildlife & Nature
Along the way, keep your eyes peeled for:
Marmots (often whistling warnings from the rocks)
Deer, pikas, and occasionally mountain goats
Birds of prey circling the thermals overhead
Wildflowers typically peak in mid to late July, painting the meadows with columbine, Indian paintbrush, and lupine.
💬 Final Thoughts
Ice Lake Basin is a true bucket-list destination for adventure seekers and nature lovers alike. The combination of glacial lakes, rugged alpine terrain, and solitude is unforgettable—but so is the climb.
This is not a casual day hike. It requires preparation, fitness, respect for the elements, and a healthy dose of humility in the face of nature’s power.
If you're ready—this place will change you.
