Big Creek Summit trail is a great way to ride the full length of the Eagle's Nest Trail 111 using the paved Warm Lake Rd and this trail. The first part of this trail is very steep and will be grueling to go up, but it does not last long before you gain the ridge.
Once on the ridge the trail will go up and down and keep a mellow grade while offering some great views of the surrounding lands. Finally, you'll drop off the ridge on a steep section of trail and head towards Eagle's Nest Trail 111. You'll need to use a dirt road to get to Eagle's Nest Trail 111, but it is a great way to make a large loop.
