The first glimmer of ice lake colorado water appeared as I emerged from the trees. The water appeared electric blue at any hour of day even when clouds covered the sky. The hidden blue lake deep in the rugged San Juan Mountains provides an unmissable experience for those who love wilderness areas and alpine exploration.
My trip started early in Silverton, a historic mining town that feels like the gateway to endless outdoor opportunities. The drive to the Ice Lake Trailhead along County Road 7 was an adventure in itself—winding past waterfalls, through shady forests, and into high mountain meadows.
The trailhead is about 7.5 miles from Silverton and offers a large parking lot, but be warned: even on weekdays in summer, it fills up fast! Arriving by sunrise is your best bet if you want a spot.
The Ice Lake Trail is part of the greater San Juan National Forest, and there’s no need for a permit if you’re doing a day hike. If you’re camping overnight, you’ll need to self-register at the trailhead kiosk. Always check current regulations.

The Adventure Begins
From the very first step, the Ice Lake Trail is all about constant discovery. The first mile starts gently, following a lively creek through thick aspen groves and pine forests. I remember the sun filtering through the leaves, painting everything in golden green.
But don’t be fooled, the trail gets tough fast. The elevation gain is no joke. Over about 3.7 miles (one way), you’ll climb over 2,500 feet, topping out above 12,200 feet at Ice Lake.
For me, the hardest part was the series of switchbacks at the halfway point. The thin air made every step a challenge, but the promise of what was ahead kept me moving.
I packed the some essentials: plenty of water, high-calorie snacks, a lightweight rain shell, and trekking poles (which saved my knees on the descent). Even in July, weather can change quickly at these altitudes. Storms build fast in the afternoons, so an early start isn’t just for the parking, it’s for safety.
Arrival at Ice Lake Colorado
I’ll never forget the moment I crested the final hill and saw Ice Lake for the first time. After a tough climb, the world opened up to a glacial cirque filled with the most electric turquoise water I’ve ever seen. The color is surreal—an effect of glacial minerals suspended in the water—and it’s ringed by dramatic cliffs and snowfields that last into midsummer.
Some hikers simply collapse by the shoreline, unable to do anything but soak in the beauty. I spent nearly an hour here, just exploring the rocky outcrops and marveling at the alpine wildflowers.
Ice Lake Basin and Island Lake
One of the best things about hiking Ice Lake Basin Colorado is the option to extend your adventure to Island Lake. From Ice Lake, a well-worn side trail climbs steeply up a ridge for about half a mile.
It’s a tough scramble, but the reward is another extraordinary lake, this one famous for its tiny island in the middle, bright teal waters, and sweeping views of Ulysses S. Grant Peak.
Island Lake feels a little wilder and less crowded than Ice Lake, and it’s a fantastic spot for photos or a peaceful picnic. I watched clouds race over the peaks and felt completely alone in the wilderness—a rare gift these days. If you have the energy, it’s 100% worth the extra effort to see both lakes on a single hike.
No hike this spectacular comes without its share of challenges. About halfway up, I realized I was moving slower than usual, probably due to the high altitude. If you’re coming from sea level, I strongly recommend spending a day or two in Silverton or Ouray to acclimatize before tackling the trail.
Exploring More Around
Beyond the two lakes themselves, Ice Lake Basin offers expansive alpine meadows, towering spires like Fuller Peak and Vermilion Peak, and endless wildflower fields.
If you have time (and energy), extend your hike to Fuller Lake, a quieter, lesser-known alpine tarn above Ice Lake. The view looking back down into the basin from here is jaw-dropping.
Done exploring the basin? Don’t pack up yet. The San Juan Mountains are a hiker’s paradise. Here are a few more adventures worth checking out nearby:
Highland Mary Lakes Trail: A 6-mile moderate hike to a series of high alpine lakes northeast of Silverton.
Animas Forks Ghost Town: Step back in time at this well-preserved mining village high in the mountains.
Colorado Trail Segment 25: For thru-hikers or day adventurers, this section connects with several alpine passes and basins.
If you’re staying overnight, Silverton has a charming downtown with gear shops, hearty restaurants, and plenty of mining history to explore. I highly recommend a post-hike burger at Avalanche Brewing Company, nothing tastes better after 8+ miles in the mountains.
