So, let’s embark on this logistical journey together, ensuring that your path to Blanca Lake is as smooth and enjoyable as the trail itself.

Getting to the Trailhead

Blanca Lake is located on the ancestral lands of the Cayuse, Umatilla, Walla Walla, Tulalip, Skykomish tribes. We are grateful for the stewards of this land past and present. We are honored to be and recognize that we are guests on this land.

To access the trailhead for the breathtaking Blanca Lake Trail, begin your journey from Baring, Washington. From Highway 2, head south onto the scenic Index-Galena Road. Follow this winding road for approximately nine miles until you reach the well-marked trailhead parking lot on your right. As you approach the parking area, you’ll find ample space to leave your vehicle.

Keep in mind that the trail is incredibly popular, so arriving early is recommended, especially on weekends or during peak hiking seasons.

Trailhead Facilities

The trailhead has a single pit toilet and some bear proof garbage cans!

Season to Visit

The best season to visit Blanca Lake depends on your preferences and tolerance for different types of weather and trail conditions:

  1. Late Spring to Early Fall (June to September): This is the most popular time to visit Blanca Lake. During this period, the trail is typically snow-free, and the sub-alpine meadows come alive with wildflowers, adding vibrant colors to the landscape. The weather is generally pleasant, making it ideal for hiking and enjoying the stunning views.

And if you’re lucky, it will be warm enough to swim in Blanca Lake!

  1. Early Fall (September to Early October): As summer transitions into fall, the crowds begin to thin out, and the trail becomes less busy. The autumn foliage starts to emerge, painting the surrounding forests with shades of gold and red. 
  2. Winter (Late October to April): Blanca Lake is accessible in the winter, but it’s a completely different experience. The trail is covered in snow, and conditions can be challenging. Snowshoes or microspikes are essential, and you should be well-prepared for cold and potentially hazardous conditions. Only experienced winter hikers should attempt the trail during this season.

Ultimately, the best time to visit Blanca Lake depends on your preferences for weather, trail conditions, and the experience you’re seeking.


A Northwest Forest Pass is required for hiking Blanca Lake. Make sure to obtain the pass before you arrive at the trailhead. This pass not only grants you access to Blanca Lake but also supports the maintenance and preservation of the trail and surrounding wilderness.

Purchase your Northwest Forest Pass here. 

An America the Beautiful Pass works as well. An America the Beautiful Pass works for all National Parks and Forests and costs $85 annually. If you plan on visiting National Parks three or more times in a year, An America the Beautiful Pass would be more cost effective.

What to Pack for Hiking Blanca Lake

With Blanca Lake being a more challenging hike, it is important to take extra precautions and be extra prepared. Here are some gear suggestions to go along with the Ten Essentials of Hiking for your trek!

If you’re unfamiliar with the Ten Essentials of Hiking, you can read about them here.

Day Pack

A comfortable day pack is going to come in handy with this hike, since you’ll be spending a lot of time on the trail. Here are two of my favorite options for packs.

REI Co-op Flash 22

The REI Co-op Flash 22 is a great beginner backpack for someone who doesn’t want to splurge on a day pack right away. I used this pack for four years before making the switch to a more technical bag. There are two options, the Flash 22 and Flash 18 if you want something smaller.

Osprey Tempest 20

The Osprey Tempest 20 is my current day pack and I love it. It fits all of my gear perfectly while resting comfortably on my hips. If you’re looking for a more technical bag and want to splurge, the Osprey Tempest is a fantastic bag.


Sturdy shoes and wool socks are a must for this trail. When you’re spending so much time on your feet on rocky and uneven terrain, a sturdy boot and blister resistant socks will be your best friend.

Oboz Bridger

Oboz Bridgers have been my go to boot for three years now. They support my ankles and have amazing traction in a variety of trail conditions. They’re great when you need a waterproof boot!

Darn Tough

Darn Tough wool socks are my go-to hiking socks. If you’ve struggled to find boots that don’t give you blisters, try using Darn Tough socks, because they make a world of a difference.

Food and Water

It is recommended to bring a 0.5 liter of water per hour of hiking. Since this trail can take some time, here are some items, I would consider packing with you on the trail for proper hydration.

3L Hydraulics Water Bladder

I drank almost all of my water on this trail. Packing a 3L water bladder is the minimum for this trail, especially on a hot day.

Katadyn BeFree Water Bottle

If you have a filtering water bottle, consider packing one like the Katadyn BeFree. When you come across a water source, you can filter more water for yourself in case you’re running low.

Bloks Energy Chews

The Cliff Blok Energy Chews are my favorite form of energy chew and source of electrolytes on the trail. They help keep me hydrated and give me the boost I need!


For most of this trail, you will be in a forested area with little exposure to the sun. 

Consider wearing clothes you’re comfortable wearing on a longer hike with layers.

If you’re going to swim, consider bringing an insulating layer and a towel!

Hiking Blanca Lake Trail

Blanca Lake Trail offers an experience like no other—a blend of challenge, discovery, and sheer natural wonder awaiting at every turn of the path. So, let’s dive into what it’s like to hike this trail and prepare to be captivated by its allure.

Woodsy Meander

I always go back and forth between liking hikes with a lot of elevation that begin with a relatively flat beginning. The start of the Blanca Lake Trail is simple and straightforward, offering a good warm-up for what is to come.

The slight increase in elevation is gradual, but before you know it you’ll realize just how steep the trail has gotten.

Forest Switchbacks

As you continue your ascent along the Blanca Lake Trail, you’ll encounter a section that truly tests your determination and rewards your efforts—the switchbacks.

The trail takes a dramatic turn here, and the forest canopy begins to thin, offering you glimpses of the rugged landscape beyond. With each switchback, you gain elevation rapidly, gaining nearly 3,000 feet in a little under 3 miles.

While this climb can be physically challenging, it’s also incredibly rewarding. Along the way, you’ll be surrounded by huckleberry bushes. The views to the east are a breathtaking distraction, with an up-close perspective of Glacier Peak on clear days, reminding you of the majestic surroundings that await.

Climbing these switchbacks feels like an achievement in itself, and it’s a journey within a journey—an exhilarating phase of the hike that brings you ever closer to the enchanting Blanca Lake. 

They are re-routing part of the trail so watch for trail signs in case the new trail has not yet been updated on your GPS.

Subalpine Meadows

Leaving the demanding switchbacks behind, the Blanca Lake Trail offers a delightful change of pace as you venture into the sub-alpine meadows. Here, the environment takes on a softer, more serene character, providing a refreshing respite for hikers.

Subalpine Meadows on the Blanca Lake Trail

The trail meanders gently through these meadows, which come alive with vibrant wildflowers when in season, particularly the vivid lupine. Walking among these colorful blooms, you’ll find yourself immersed in a scene straight out of a nature lover’s dream.

As you continue on this stretch of the trail, you’ll eventually reach Virgin Lake, a charming stopover that’s anything but stagnant in terms of its allure. This picturesque lake, while lacking a visible inlet or outlet, serves as a vibrant ecosystem fed by snowmelt and rainwater. By late fall, the water takes on a different character, resembling more of a bog than a lake, yet it remains a habitat for frogs and salamanders, providing yet another fascinating aspect of the natural world to observe. I would not recommend jumping into Virgin Lake late in the season.

Leaving the quiet shores of Virgin Lake behind, you’ll find the Blanca Lake Trail embarking on another chapter of your alpine adventure.

Virgin Lake along the Blanca Lake Trail

This is strictly a day area so backpackers need to set up camp closer to Virgin Lake. The descent down to Blanca Lake is a steep, rocky and for lack of better words, rooty one. The narrow switchbacks leading down to the lake are packed with trees that offer small glimpses of the beautiful blue lake in the distance. 

And then, as you continue your ascent, the landscape begins to shift once more. You’ll round a final point, and there it is—Blanca Lake in all its glory. 

Blanca Lake Overlook

This final leg of your adventure takes you from the vantage point of the overlook down to the pristine shores of Blanca Lake.

The trail descends somewhat more gently at this stage, gradually leading you closer to the water’s edge. The landscape transitions once again, as you leave the rocky outcrops behind and return to the embrace of sub-alpine meadows.

Hike down to Blanca Lakefront

The transition from trail to lakeside is marked by the presence of driftwood, forming a natural beach where you can relax and savor the pristine beauty that surrounds you.

Above the lake, the Columbia Glacier delivers its contribution via a twin waterfall, a sight that adds to the otherworldly quality of the lake’s robin-egg blue waters. 

After a nice lunch and dip in the cool waters it is time to climb back out of the basin and head down the trail. I was not in a rush to do that.

Commonly Asked Questions

In this section, I’ve compiled answers to some of the most frequently asked questions to ensure you’re well-prepared for your adventure.

Can you swim in Blanca Lake?

Absolutely, you can take a refreshing plunge into the crystal-clear waters of Blanca Lake. While the water might look a bit chilly, especially given its stunning turquoise hue, many hikers can’t resist the temptation to cool off after their trek.

Keep in mind that the lake’s color comes from glacial meltwater, which means the water can be quite cold, even in the summer months. So, prepare for a brisk swim and enjoy the invigorating experience of floating in one of Washington’s prettiest alpine lakes.

Is Blanca Lake hard to hike?

Blanca Lake Trail is a challenging hike, there’s no sugarcoating it. The trail greets you with a series of steep switchbacks that can leave your legs feeling the burn. Over the course of about three miles, you’ll gain nearly 3,000 feet in elevation. 

It’s a workout, to say the least, but let me assure you, the rewards are more than worth the effort. The trail is well-maintained, so while it’s demanding, it’s also accessible to determined hikers of various skill levels. Just come prepared with proper footwear, plenty of water, and a willingness to embrace the climb.

Why is Blanca Lake so green?

Blanca Lake’s mesmerizing greenish-blue color is a result of glacial meltwater mixed with fine particles of rock known as glacial till. Glacial till is created as glaciers move over the land, grinding rocks into a fine powder. When this glacial till is suspended in the lake’s water, it scatters sunlight in a way that reflects the stunning turquoise-blue color you see. It’s a natural wonder and one of the defining characteristics of Blanca Lake that makes it so captivating.

Can you backpack to Blanca Lake?

No you cannot backpack to Blanca Lake. 

However, you can backpack the Blanca Lake Trail and stay overnight near Virgin lake. Backpacking near Virgin Lake in the designated campsites is indeed a wonderful option for those looking to extend their adventure along the Blanca Lake Trail. It provides an opportunity to immerse oneself in the serene wilderness of the Henry M. Jackson Wilderness while enjoying the stunning surroundings of Virgin Lake.
