I have done hundreds of hikes in Colorado, with a few leading me to isolated mountain lakes, but one stood out among the others, and that was Ice Lake Basin. I am not going to lie; the hike is not easy and can feel as grueling as 14er, but once you reach the top, you will understand why we all put ourselves through it. Here is your hiker’s guide to Colorado’s prettiest lake, Ice Lake Basin.

Hiking Ice Lake Basin

The round-trip hike to Ice Lake is approximately 8.3 miles, and you can extend the hike to visit Island Lake, which adds about 1.5 miles.

The hike is challenging, with an elevation gain of about 2,877 ft, starting at around 9,840 feet and reaching Ice Lake at approximately 12,260 feet.

While it’s not on Colorado’s list of 13ers, it does feel like it should be.

Ice Lake Basin is situated in the Uncompahgre National Forest, near Silverton in southwestern Colorado.

Ice Lake Basin Hiking Guide

Your hike will start by Begin your hike from the Ice Lake Basin Trailhead, located near the South Mineral Campground.

With incredible views, you will trek upward along various switchbacks through the San Juan National Forest.

This loop can be tough if you aren’t used to the elevation gain.

Throughout your journey to Ice Lake, you’ll pass waterfalls and flowing creeks while enjoying the fresh air of the mountains!

Once you reach the top, you will leave the forest and be exposed to the sun, hiking on top of the world.

Then, you will see it for yourself, the incredible Ice Lake!

As you can see from my photos, the lake is striking blue and surrounded by bright green grass and towering mountains.

The upper basin is surrounded by incredible peaks, such as Vermillion Peak, Fuller Peak, Pilot Knob, and Golden Horn.

Once at the gorgeous Island Lake, Grant Peak looms overhead.

From here, you can continue to Island Lake if you want!

A beautiful, smaller lake nearby with a distinctive island in the middle, also known for its vivid colors.

Can You Swim Here?

Yes, you can swim in the Ice Lake Basin, but it is very icy. Even on a hot summer July day, it was still freezing.

I recommend soaking your feet, but if you feel brave enough, you can take a quick cold plunge! It can be dangerous due to how cold it is from the snowmelt and elevation.

Ice Lake Basin Camping

You are allowed to camp at Ice Lake Basin, but I don’t recommend it unless you are prepared. It gets very windy on top of the mountain, thanks to its high elevation and Colorado winds.

Instead, try the campground near the trailhead, South Mineral Campground, or take a ride over to The Best Colorado Glamping Cabins Are At Durango Riverside Resort!

Best Time Of Year To Hike Ice Lake Basin

Summer is the best time of year to go, preferably from mid-July to late August.

This is when the snow melts, and you can capture the beautiful green surroundings. I hiked it in July, and this is what I looked like.

The basin is blooming with wildflowers during the summer, creating a colorful and picturesque landscape.

4. Acclimatize:

• If you’re traveling from lower elevations, spend a day or two in Silverton or nearby high-altitude areas to acclimate to the elevation. This can help prevent altitude sickness and make your hike more enjoyable.

5. Pace Yourself:

• The hike involves a significant elevation gain, so pace yourself accordingly. Take breaks as needed, especially if you’re feeling tired or short of breath due to the altitude.

6. Leave No Trace:

• Practice Leave No Trace principles by packing all trash, including food wrappers and other waste. Respect wildlife and avoid feeding or approaching animals.

7. Stay on the Trail:

• Stick to designated trails to protect fragile alpine vegetation and prevent erosion. Avoid shortcutting switchbacks, as this can damage the trail and surrounding ecosystem.

8. Be Prepared for Wildlife:

• The forest is home to various wildlife, including marmots, pikas, mountain goats, and even bears. Keep a respectful distance from animals and avoid feeding them.

9. Drink Water:

• Drink plenty of water to stay hydrated, and listen to your body if you experience symptoms of altitude sickness, such as headache or nausea.

10. Enjoy the Scenery:
