Ice Lake and Island Lake, Colorado: BEST hike near Silverton!

ByTahir

I had long heard about the mysterious Ice Lake Basin in Colorado, tucked away in the San Juan Mountains. Ice Lake and Island Lake mystified me, and I dreamed of one day gazing upon their shores. What I didn’t realize at the time was that I could visit both on a single hike!

In September 2022, I finally got this chance, and let me tell you, this hike far exceeded my expectations, and I would hike it again in a heartbeat. Imagine Ice Lake with its vibrant turquoise waters, and Island Lake glowing in a striking emerald green, surrounded by incredible scenery in every direction. It’s breathtaking!

To reach the trailhead from the south (Silverton, Purgatory Resort, or Durango), follow these steps:

  • Step 1: Head north on Highway 550
  • Step 2: Just two miles past Silverton, look for a small sign reading “National Forest Access South Mineral Campground.”
  • Step 3: Turn left onto FR 585. This well-maintained gravel road winds downhill through the forest. My Honda Civic made it with ease.
  • Step 4: In about 4.5 miles, you’ll see the trailhead on your right, directly across from the South Mineral Campground.

Coming from Ouray essentially reverses your first two steps:

  • Step 1: Head south on the Million Dollar Highway (Highway 550).
  • Step 2: As you get close to Silverton, look for a small sign that reads “National Forest Access South Mineral Campground.”
  • Step 3: Turn right onto FR 585.
  • Step 4: Drive roughly 4.5 miles to the parking area on your right.

Quick Tips:

  • Arrive Early: The lot fills up fast. Aim to arrive before 8 am during peak season (June through August). I grabbed one of the last spots at 8:30 am in mid-September.
  • Dirt Road: The last 4.5 miles are an unpaved dirt road, but my low-clearance sedan handled it just fine.
  • Road Conditions: 4WD would be recommended when snowy/muddy

The beginning of the Hike

As I started hiking, I spoke with some volunteers running a booth dedicated to responsible hiking and Leave No Trace principles. I thoroughly enjoyed chatting with them, and I completely agree that it’s our responsibility to travel mindfully and help preserve these gems for future generations.

Sustainability is one of the major pillars of Grounded Explorers, and I encourage everyone to learn and practice these principles on every hike

The Hike To Ice Lake and Island Lake

While many (including AllTrails) disagree with me, I highly recommend hiking to Island Lake first. Why?

First off, reaching Island Lake means 98% of the elevation gain is over. If you know me, regaining elevation once I have started hiking downhill isn’t my favorite. Secondly, the view of the Ice Lake Basin hiking down from Island Lake is phenomenal, which would be behind you if you hiked to Ice Lake first.

Ice Lake and Ice Lake Basin: coming down from Island Lake

Part 1: The first two miles

The first two-ish miles gain about 1600 feet (3.6ish km and 488 m) to the Ice Lake and Island Lake Junction. This scenery here is stunning. The trail winds through dense forest before opening into a meadow framed by fire-burned trees left by a 2020 human-caused wildfire. Even in mid-September, I saw wildflowers, and I can only imagine what they look like at their peak!

In the meadow, you will spot Clear Creek Falls, a stunning seasonal cascading waterfall. The flow was low during my visit, but I bet it roars to life in spring! After a few switchbacks, look for a short spur trail that can get you up close to the falls. At the time of my hike, I didn’t know that the spur trail continues all the way to Clear Lake, another spot on my list!

A few more switchbacks through the old-growth forest bring you to an expansive meadow with distant peaks in view. Those mountains actually frame the Ice Lake Basin. Soon you will reach a junction, and I recommend turning right toward Island Lake!

Part 2: Hike to Island Lake

After leaving the meadow, the trail quickly steepens! The remaining 1.2 miles gain roughly 1,200 feet (1.9 km and 320 m), with a steeper grade than the first half. Here, the terrain is more open with panoramic vistas in every direction! I highly recommend wearing sturdy hiking shoes and bringing trekking poles for this climb.

Keep your eyes peeled, as you will get a fantastic view of the canyon you drove through to reach the trailhead, as well as the parking lot. The scenery here amazes with every step! If you are a sucker for open alpine views, you will love this section of the trail!

However, it remains very steep. You’ll know you’re close to Island Lake when the trail suddenly flattens in another meadow with a small pond, surrounded by rugged peaks. Keep walking, and Island Lake will finally pop into view. It’s one of those perfect turn-the-corner reveals that make the steep climb totally worthwhile!

Island Lake

I remember chatting with a hiker who was on his way down. He told me that Ice Lake was way more beautiful than Island Lake. After the hike, having experienced both myself, I don’t see why they needed to be compared: both lakes are beyond incredible, unique, and worth hiking to. Forget the comparisons, go see both!

Island Lake really amazed me with its vivid emerald green waters, which changed in intensity as the light shifted. The color of the lake honestly rivals Emerald Lake in Yoho National Park. The real standout feature, however, is the small island sitting right in the center.

When I arrived, I was pretty much alone, though eventually two hikers showed up with inflatable kayaks. I can’t imagine carrying that the entire hike up, but I am certain they didn’t have any regrets! I watched them paddle out to the island for a lunch break!

I stayed there for over thirty minutes, soaking in the views and refueling with snacks. While resting, I noticed a steep trail behind the lake with tiny dots making their way towards V2 peak. Given that I was in the worst shape of my hiking career at the time, that incline felt daunting. But one day soon, I will summit V2 peak!

Part 3: Island Lake to Ice Lake

From Island Lake, you will ascend a small hill, from where you will be treated to one of the best views of the entire hike! Ice Lake pops into view alongside the Ice Lake Basin, the Vermillion Peaks, and the canyon below where our hike began. This is the second reason I recommend going to Island Lake first.

After taking in the view, I started my descent. The trail quickly drops about 200 feet over half a mile to reach the shoreline of Ice Lake. This section is quite rocky, so my Columbia hiking shoes really saved me! They provided comfort with a solid grip on the loose rocks and instilled confidence in every step!

Ice Lake

Ice Lake stands out as a postcard-worthy destination on its own. I would repeat this hike over and over just to see it again, but pairing it with Island Lake makes this trail truly special. Walking along the shoreline is a surreal feeling, gazing at the “Gatorade blue” water set against the stunning Vermillion Peaks.

I spent half an hour enjoying the view and would have lingered longer if time had allowed. Several nice snack spots line the shore, and while an unmaintained trail loops around the lake, I prefer sticking to the established trail. Staying on marked paths helps protect this fragile environment.

Ice Lake is definitely the most popular of the two. By 1 p.m., at least 20 hikers had already gathered along its shores. In the future, I would spend more time here, perhaps even hiking the extra mile southwest to Fuller Lake. There’s just so much here waiting to be explored!

Part 4: Ice Lake to Trailhead

From Ice Lake, the trail descends quickly back toward the junction with Island Lake. This section is pure eye-candy for alpine scenery lovers! After the steep descent, distinct rock formations emerge, reminders of the area’s distant volcanic past

You can also spot the vivid blue stream leaving Ice Lake and winding down into the basin, with scattered white rocks in the riverbed.

Once you reach the junction, the trail simply backtracks through the canyon. I prefer downhill hiking, so I was on an absolute “hikers-high” the entire hike down. Starting at 8:45 a.m., I finished at 2:30 p.m., logging just under six hours, including two long breaks at each lake. The sight of the parking lot is a welcoming sight

Recommended Gear

Here is exactly what I packed on my trek to Ice Lake, along with the gear I rely on for nearly every hiking adventure!

My Backpack and what’s inside

  • Backpack: My Osprey Stratos 24L daypack handled the steady climb up to Ice Lake perfectly. It sits securely on my back and holds everything I need.
  • Hydration System: I stick with a Platypus 3L hydration bladder because it doesn’t have that plasticky aftertaste I get from other brands. Staying hydrated on the hike is effortless when your water tastes clean.
  • Water Bottle: I always carry my trusted Nalgene 48-ounce bottle as a backup. It is perfect for mixing electrolyte powder and gives me peace of mind if the bladder runs low.
  • Water Filter: I like to filter water directly into my Nalgene bottle using the Katadyn Gravity Water Filter system. Seriously, this thing is amazing; it can filter 3L in a minute. Before, I used a Sawyer Squeeze filter, and I hated that thing (It took me 10 minutes to barely filter 2L, not to mention all the squeezing effort). I have zero regrets about this investment!
  • Trekking Poles: My ALAFEN Collapsible Ultralight Poles are a must for this trail. They provided stability on the steep sections and fold down perfectly into my bag when the terrain flattens out.
  • The Ten Essentials: Read this checklist before heading on the Ice Lake hike. Having navigation, extra layers, emergency supplies, and sun protection makes all the difference when mountain weather shifts quickly.

Footwear

  • Footwear: The Columbia Men’s Transverse Hike Waterproof Shoes delivered exactly what I needed on the rocky, uneven trail to Ice Lake. Excellent traction and solid support meant zero blisters from start to finish!
  • Socks: Smartwool hiking socks have been a game-changer for my feet. The moisture-wicking and cushioning kept my feet comfortable through every mile

Tips

  • Carry Bear Spray: Bear, Moose, and Elk are commonly sighted on this trail.
  • In the summer months (May – August), start the hike early for several reasons:
    1. Easier to find parking
    2. Less direct sun and heat exposure
    3. Afternoon thunderstorms are common and can appear without warning
  • Stay Hydrated: I carry at least 3L of water on any hike.
  • Electrolytes: Equally important are electrolytes! I go for at least 1L of electrolytes. And I use these Gatorade packets, they’re super convenient on the go

Camping At Ice Lake Basin

While I haven’t camped in the Ice Lake Basin, I have researched this topic thoroughly so that when I have the time, I will be ready to go! Backpacking here looks spectacular, but it is something that should be done with extreme care. Here is what I have learned so far.

Where to pitch your tent

While camping is currently allowed in the Upper and Lower Ice Lake basins without a permit, Forest Service guidelines strongly advocate for setting up your tent in the lower basin. This spot provides better tree cover to hang your food, though I recommend carrying a bear canister regardless.

The lower basin also features more stable ground for tents, and keeps heavy foot traffic away from the incredibly sensitive, slow-growing tundra above timberline.

Leave No Trace

Campfires are strongly discouraged near Ice Lake and Island Lakes due to the risk of severe soil scarring, which can destroy the fragile alpine tundra. Additionally, there is no firewood available to collect. Instead, use a compact stove system like a Jetboil, which can double as a cooking and heating system.

Commit to packing out all trash, toilet paper, and human waste. For waste, I recommend wag bags, and I know, the idea of carrying it out is gross, but your actions will be helping protect this beautiful area. If digging is your only option in the lower basin, create 6-to-8-inch catholes at least two hundred feet from water and trails.

Stay on marked paths to prevent erosion, yield off-trail carefully, and never feed wildlife! Heavy summer visitation makes trail etiquette and solid prep the absolute key to protecting this fragile area.

Be Prepared

Bring a reliable water filter, boots with a strong rubber grip, and be ready for rocky terrain. Altitude sickness hits unprepared hikers quickly, so pace yourself, hydrate constantly, and eat salty snacks to keep your energy steady above 11,000 feet.

Once you pitch camp, the payoff is immediate: wildflower-lined meadows, mirror-still lake reflections, and sweeping ridge views that make every heavy mile completely worth it.

Best Time To Hike

Summer is the best and most popular time to hike to Ice Lake and Island Lake. Wildflowers typically bloom in the second half of July, though they can linger into August depending on snowpack and rainfall. While direct sun exposure makes it feel warm, the temperature stays relatively mild at around 70°F (21°C).

Autumn is also amazing, which is when I last visited Ice Lake. Late September is typically peak fall color, but I had arrived a week too early. This hike sits above the usual elevation for Aspen, and other leafy deciduous trees to grow, so most of the color is in the brush. Temperatures remain mild, but can change quickly, so it’s a good idea to bring a sweater.

Winter brings unique challenges since FR 585 (the access road) isn’t plowed, so hikers must plan for nearly nine additional miles on skis or snowshoes. Spring creates muddy trails from melting snowpack and wildly fluctuating temperatures. Pack waterproof boots, gaiters, and warm layers for rapidly shifting mountain conditions.

Final Thoughts

The hike to Ice Lake and Island Lake in Colorado’s San Juan Mountains ranks easily among the best in the entire state! You will encounter stunning scenery that includes forests, meadows, basins, and two alpine lakes worthy of being their own destinations.

With proper preparation and care for the environment, everyone can enjoy this trail while ensuring it stays pristine for future visitors to cherish it as much as we do! If you haven’t already, add this one to your bucket list and enjoy your time out there!
