Before I start waxing poetic about these two (beautiful) trails, let me note that Blue Lake is more like 1.8 miles than 1.4 and Dock Butte is closer to 5.3 miles than 3.
The plan was to hike an easy 4.5 miles on what was expected to be a scorcher of a day--but by the time I reached the end of the Dock Butte trail the only thing on my mind was "there is NO WAY I've only hiked a measly mile and a half." So on my GPS went for the hike back down the the Blue Lake Junction. I was pleased as punch to find out that by the end of my hike I'd be adding a solid 7 miles to my mileage goal.
If you're looking for a super quick hike, you might want to rule this out, but I strongly suggest you don't.
The trail to Dock Butte alone is enough to make you want to never leave. Soft yellow sand and glassy sounding rock make up a trail that defines idyllic. If that's not enough for you, though, then you'll be happy to hear that the views leave nothing to be desired. Kulshan towers over you and gives you a true sense of is hugeness. Off to it's left you see the Twin Sisters, dwarfed by their snowy neighbor. To the other side you look out over stacked hills and the beautiful Baker Lake. You're sure to be in absolute awe.
Jump over to Blue Lake and you're suddenly confronted with a crystal clear and not-too-cold mountainous lake. Make sure you're not coming here on a time crunch, because you'll have one heck of a time trying to drag yourself away. I spent no less than an hour dipping my feet in the water and taking a (frankly ridiculous) number of photos.
I'm not one to rate my hikes, but this one was definitely a 10/10.
