Mount Si Main Trail


Day Hike - Mount Si Main Trail

This is a great stand-alone day hike or conditioner. Depending on weather and or trail conditions, we will have a few options to incorporate or divert to as required. Though not part of the "Conditioning Hiking Series", the primary purpose of this trip is conditioning for glacier climbing.

  • Moderate/Strenuous
  • Challenging
  • Mileage: 8.0 mi
  • Elevation Gain: 3,150 ft
  • Pace: 1.8-2.3 mph

Meet and assemble at Mt. Si main trailhead (near the sign by the pit toilets) at  7:45 AM.   Brief introductions and trip review and depart by 8:00 AM.  We will hike up the Mt. Si main trail to the base of the Haystack.

Trip open to all branches and eligible members.  This hike  is for developing/improving physical conditioning for glacier climbing.  As part of my own conditioning series, we are increasing our pace and carried weight.  Mountaineering Boots required.  Recommend  carrying a minimum of 30 lbs. but not more than 40 lbs./25% of  your body weight without submitting prior experience and details with your request to register.  This is not a hike recommended for beginners.  The pace is listed as 1.8-2.3 mph, but we will adjust to trail/snow conditions and a pace that allows conversations.  Should the weather and or trail conditions work against us, we will discuss  and agree to alternatives as a group, such as diverting to the Mt. Si connector, instead of the summit (for example).  Other than personal bio-breaks, we will stay together as a group within speaking distance of one another.  Our plan would be to spend no more than 15-20 min. at the false summit to take in the views, rest, and enjoy a snack, prior to descending.  This is NOT a snowshoeing trip, so per The Mountaineers standard's, should we run into snow that is beyond mid-calf/below the knee, we will turn around
