Riders often stop at the Fern Lake Tr1436 TH, but the moderate North Fork Entiat River Tr1437 slope continues for another mile, then rapidly ascends to Pyramid Mtn Tr1433.

Fern Lake Tr1436 is a high mountain lake and the trail ascends 1800' 1mi, and that 22% wall-climbing exercise starts at 5200'.

This will be too steep for most riders, and those thinking of the steep descent will have to watch for oncoming traffic on this spur trail. Fern Lake Elevation Profile MapFern Lake Elevation Profile Map

There are several loop options, depending on climbing ability, with the 800' (.5mi) Grouse Pass ascent to consider.

Entiat, Pyramid, Pugh 18mi CW Loop (5300' ascent): The last 1mi of N. Fork Entiat Rvr Tr1437 ascends 800', a hike-a-bike for virtually anyone, but a fast way to get to Pyramid Mtn Tr1433, leaving the Grouse Pass ascent as the remaining challenge.

The final 2.5mi steep, switchback Pugh Rdg Tr1438 descent is near-epic.


Pyramid Cr/Mtn, Entiat CCW Loop: At 17mi and 4700' ascent, with 7mi of sustained climbing to Grouse Pass, this epic route is for strong climbers, or those who like to hike...a lot.

This is a way to experience N. Fork Entiat Rvr Tr1437 as a wild downhill ride, with the option of ascending the Pyramid Mountain summit on Pyramid View Point Tr1441.

Directions: NW Forest Pass required right at the TH. From Ardenvoir continue on FR51 to FR5100 to FR5606. View Larger Map. No Map?.

North Entiat River Area Topo Map

  • TH: Cross Grouse Creek, followed by 1mi of flat terrain, then a brief climb to the Pyramid Cr Tr1439 intersection at 1.2mi, just past the Pyramid Creek crossing. Cross another creek at 1.5mi, with the terrain becoming more rugged.
  • 2.6mi: After crossing another creek, pass the Pugh Rdg Tr1438 intersection on the right. The ascent gets a little steeper, up to 4.5mi, then flattens out until just past the Grouse Creek crossing at 5mi.
  • 5.7mi: After a steep climb from the Grouse Creek drainage, reach the Fern Lake Tr1436 intersection on the left. This is a good turnaround point, but the trail continues another mile before starting the Pyramid Mountain Tr1433 ascent. Hiking to Fern Lake is another option, then head back to the TH.
