Day Hike - Rattlesnake Mountain (East)

  • Strenuous
  • Challenging
  • Mileage: 8.6 mi
  • Elevation Gain: 2,500 ft
  • Pace: 2-2.5 mph

With the virus situation the Mountaineers advise avoiding carpools except with people that you know well.  Let's plan to meet at 7:30AM at the first Rattlesnake Lake parking lot that you come to on the right as you enter the park - google map location

This is a great, vigorous hike that climbs steeply to the ledges for views, then turns left and climbs more gradually through forest to northward views over Mount Si .  The final few miles may be hard packed and slippery snow so poles and microspikes will be required.

We will be hiking at a brisk pace without a lot of rest stops so please don't choose this hike if you don't have recent experience at this challenge level.  We'll stop for approx 20 minutes at the east peak viewpoint before heading back.

Details on weather and gear recommendations will be provided in an email to the group later in the week.
