  • Moderate/Strenuous
  • Moderate
  • Mileage: 9.0 mi
  • Elevation Gain: 3,200 ft

We will meet at 7:30 at the Preston P&R or 8:30 at the trailhead.  

Please carpool!!

Directions to the trailhead:

Exit highway I-90 at Hyak exit 54. If you are coming from Seattle, turn left at the stop sign at the end of the ramp. Proceed under the highway and continue a short distance to a stop sign. Reset your odometer here and turn right onto Gold Creek Road.

This road will parallel the highway for a while before turning up into the hills (road called FS 4832, Rocky Run Rd). At 2.5 miles it will turn to dirt with little warning (happens as the road rises away from I90). At 3.8 miles there will be a left turn at a switchback -- DO NOT TAKE THIS (Stay on main road). At 3.9 miles take the left fork. At 4.3 miles you will reach the parking lot on your left signed as Mt Margaret trail head.  

We will do this hike at a moderate pace, but the trail has only recently cleared of snow so plan for mud and almost certainly some downed trees to climb over/under/around which may make this a more challenging hike!  Participants should be comfortable doing hikes at the high end of moderate and must have recent experience over 7.5 miles and 1500 feet of elevation gain.  

The trail heads straight up the side of Mt Margaret initially through an old clearcut, but that soon turns into an old growth hemlock forest.  Upon reaching the top just past 5000 feet, we'll mostly level out and traverse across Mt Margaret on trail with a high point at 5200 feet and some talus expected.  We'll pass Twin Lakes and then descend a total of 600 feet to Lake Lillian.  

I'll bring a filter so we can replenish water, but please bring at least 1.5 liters and no more than 2.0 liters due to weight.  Trekking poles are recommended and you must have good hiking shoes/boots to protect your feet from talus rock.
