Once you've completed the scramble to the top, get 360 degree views of Washington. Hit the trail early if you're hoping to spend the night in the lookout. It's first come, first served.

Be careful when heading up this 4.5 mile trail since there can be snow coverage into the summer. When you start the trail, you'll get a little tree coverage as you start climbing up. Unfortunately, the shade starts to dissipate after about a mile, where you'll cross over Sibley Creek and enter the basin. As you climb, the view gets better - take time to check out the valley below and Mt. Baker. Once you've hiked for about 2.5 miles, the trail will ease its incline grade a bit and allow you to pass through the meadow and catch your breath.

After another mile of hiking, you'll start to get views of the surrounding peaks like Forbidden and Klawatti. Once you reach the saddle, you'll be able to see Hidden Lake below. There's no defined trail to the lake; it's about a 1/2 mile boulder scramble if you're looking to get down there. For the last bit of the hike from the saddle, you'll be scrambling up boulders for 0.5 miles to make it up to the lookout.

Staying here is first come, first served.

Very challenging, start early so u can get to the top for lunch

This one has it all doesn't it? Hike through a dense forest, coming up through the valley with wildflowers, climbing the ridge and stopping every 10 minutes to marvel at the peaks around you. And then the scramble to the lookout...breathtaking. Oh yeah and the ice blue lake ain't bad either. Perfect hike.

Hiked this on October 6, and was greeted with a nice layer of snow and ice over much of the upper part of the hike. Made for adventurous hiking and beautiful scenery, with a bit of a "high alpine" feel. Fall colors blooming on the drive in and along the lower parts of the hike, and cold-but-not-freezing temps.

It’s just awesome. No other words. Plain awesome.

This hike was dope. Starts out in an alpine meadow and only gets better. Highly recommend

Definitely one of the best ways to experience the PNW and the views! I'd spend a night up there to see the sunset and sunrise and just sit back and relax

Hiked up to the lookout at the end of August and camped over-looking Hidden Lake for the night. First, the hike up was fun....about 3,000 ft elevation gain in 4.5 miles, but fun nonetheless. We went out early hoping to get to the lookout first. We hung out at the lookout for a couple of hours before making our way down towards the lake. We decided to set up camp on the ridge overlooking the lake and man am I glad we did! I woke up around 5:30am, peeked out of the tent and saw just a slight orange tint to the sky. Grabbed my camera and spent the next 2 hours taking some incredible pictures and video of the rising sun. My only regret is not staying longer. In hindsight, we should have prepared to stay up there for two nights and on the second day just explore around the lake and lookout. But this is definitely one of my favorite and most memorable hikes I've had.

A stunning hike, and a great way to make friends by sharing the lookout with some other fellow solo backpackers for a fun night of stories and laughs. Just beware, the road to the TH is rough, like, "this is the end, the end of my Honda!" being shouted several times, rough. In addition, the clouds and storms roll in fast here, what was a sunny calm Thursday evening quickly turned to a Friday morning snowstorm that left me with only 20 feet of visibility while trying to scramble down the peak with wind and ice. Yet, oh so worth it!

My wife and I hiked this trail on a beautiful day in early September. We started late (1pm) so only made it to the saddle overlooking hidden lake and then turned around. It was totally worth it. The views got progressively more amazing the higher that we climbed. This hike crosses beautiful woodland then alpine meadows, then rocky tundra. We took our time climbing up as there were so many wildflowers and fungi to spot. There were Pika everywhere on the upper slopes - easy to hear but difficult to spot. Highly recommend this hike. Allow 3-4 hours up, 2 hours down.
