Lost Lake via Greenwater lakes
Trip Times: 9:40a-2:20p
Distance: 12.2 mi

Road to TrailHead: FR70 off of 410 is fully and nicely paved 2 lanes. Yes to the trailhead parking lot. Lots of campers on the road up..and a target shooting range too. The TH has two vault toilets..decently clean. The TH can accommodate about 20-25 cars easily in marked stalls. Really.

As you begin the hike. The trail to the greenwater lakes (~2 mi) has minimal overall elevation gain and the trails are good and wide. There are some short upward stints, but come back down. Overall, anyone can do it easy. You'll also get to cross numerous wood bridges (one notably is tilted, and one further down is a skimpy makeshift log bride). Both funny to look at, but fully functional nonetheless. You'll see a lot of camps and tents along the trail. As you pass the Greenwater lakes (2), you'll soon enter the Norse Peak wilderness boundary (signage)...and yes the elevation gains start to appear more often. About 3/4 mi further, you get to a clearly marked junction for Echo Lake and Lost Lake.

As I choose the Lost Lake journey, the elevation gains start right off (see pic)...up and up. Not crazy incline (maybe 400-600 ft/mi rate). The trail is rooty and rocky at times. And as you get futher along the vegetation does cover the trail slightly (indicating it is not highly trafficed). All in all, its easy to follow (be careful of ticks - wear Deet and Premethrin). You'll pass a couple a small streams and you can hear the Lost Creek runoff making music as it cascades down the mountain. Eventually you hike past Quinn lake (small hidden behind trees - but you can walk your way down to it). A bit further and nearing Lost Lake, you'll walk through an eerie place...boulders, burnt tree field. So sad to see. After treking through that, you've arrived at Lost Lake.

You can clearly see a trail around the lake. I tried to walk it, but near the lake ingress (south side), the ground is ver saturated and grassy with lots of fresh (literally) cougar and bear paw prints leading to the water from the surrounding woods. Felt a bit uneasy. So just turned back and headed back...after talking lots of pics.

Overall a very good hike.

The trail was nicely maintained and has had some recent work.
The horses were sad to see yellow jackets about 3/4 of way to top.
On horseback the trail is a challenge best for experienced trail riders.

The trail started (for us) at the Green Lake Trailhead. A few miles of relatively flat walking til we hit the second green lake. the bridge was out there so we went over the logs that had fallen to cross the water. Once on the other side, the ascension starts. Walking for a little while, you hit the "y" in the road that takes you to (left) echo lake and (right) lost lake. We took the right and it's a pretty steady uphill hike. It was snowing and everything was white and beautiful. Finally arriving at the lake on the left, we noticed that it was hidden with no signage whatsoever. Thank goodness for the steps in the snow so we could follow. Overall, it was a majestic little lake that was a brilliant bluish green. Very peaceful and st this tone
