Alta Peak is a classic summit that is located in the Alpine Lakes Region. Home to stellar views, Alta Peak is popular destination for those want to bag a beautful peak along with checking out the amazing Rachel Lake. One of the major advantages of this mountain is that it is only 12 miles roundtrip and the technical difficulty of this peak during summer is barely Class 2, with only one small section of exposure on a narrow ridge near the top. In summer this narrow ridge will only require one to use a little caution on their way to the summit. However with a coating of snow this mountain can get very sketchy very quick. It is an ideal late summer-early fall summit to go for because the trail up is then snowfree and the berries are out towards the high country.
The route up starts with the Rachel Lake trail which barely gains any elevation in the first 3 miles. It goes up the stream valley up to beginning of the ridge. The trail then steepens and rises up to Racheal Lake. From there a climbers path lies and heads to the right up Rachel Lake. It alternates between moderates and steeper pitches. Once you attain the ridge the trail follow the ridge to the summit. Though it is a well used climbers path there is one section where a little caution is need about 1/2 mile before the summit. Total one way trip time if conditions are ideal would 2-4 hours up or 5 to 8 roundtrip not including photo taking, which will be a lot.
There are excellent views on this summit. You can go through an entire roll of film from this summit. These amazing views include Rainier, Glacier, Sloan, Hibox, Chikamin, Thomson and most all the peaks in the vicinity. Most who summit Alta agree that it is one of the most beautiful summits in this region in terms of great views.
From Seattle, take I-90 E to Exit 62. Turn left on Kachess Lake Road #49 and follow it for about 5 miles. At the junction, turn left onto gravel Road # 4930. The Rachel Lake trailhead will be about 4 miles on the right-hand side of the road.

Red TapeNorthwest Forest Pass required to park at the trailhead. A self-serve Alpine Lakes Wilderness Pass is required for trail use (free of charge).
When To ClimbAlta Mountain can only be attempted when the Rachel Lake Trailhead is open. There is a back wy to Alta Peak from Rampart Ridge but this again can only be done in summer. The typical season to do Alta Mountain is July to October. However once the first heavy snowfall hits Alta the condtions can quickly deteriorate and the final ridge to the summit can be very sketchy. With a good snowpack and good steps this should not be a problem. However with loose snow this ridge can be very hazardous.
CampingCamping is allowed under the Alpine Lake Wilderness regulations.
