A difficult but not extreme loop with spectacular views and a fun scenic descent.
The road climb is fairly easy but the ridge trail has a few steep sections before the final mile that's pretty much all hike-a-bike but the scenery will help you forget that. Make sure to check out the lookout point that's only about a quarter mile of hike-a-biking but offers great views of Pyramid mountain, Glacier peak and the North Cascades.
The descent is fairly steep and technical at first but mellows out pretty quickly. Because of a recent fire, you can still enjoy mountain views all the way to the bottom. Warning: there will likely be many blowdowns early in the season. Wait for our moto friends to clear the trail. Call the ranger or ask on thumpertalk.
Check out Myrtle lake only a short ride up the Entiat River trail before returning back to the car.
