What makes the trail tough? Aside from how long it is (and the fact that it's a point to point!), there's the steepness. This trail has several steep sections, and they run both ways. No matter which end you start from, you're going to be facing an uphill climb! The trail is far from the main path, so you're going to have to handle any problems yourself. As a final note, you will probably come across downed trees at some point on your hike. Locals work to keep the path clear, but tree falls are not uncommon, especially at the beginning of the season!
What's working in your favor? The path is clearly marked. It's hard packed dirt all the way along, making for a stable and walkable surface. The path is popular enough that you're going to wind up sharing the road, so you're not totally alone. Plus, the views of Idaho's forests, hills, and meadows are inspiration enough to keep going!
The first two miles of the trail are a simple descent along a single track. From there, you're going to descend until you cross a creek and head up the other side. Ignore the first Twin Creek sign you come to--you want Twin Creek #108. Take a left there, and you'll have crossed from the "Divide" trail to the "Twin Creek" side. The trail still fluctuates, but it's more down than up all the way to Twin Creek itself! Once you ford the creek, it's just two miles to the end of the trail!
Pawsome hikers and woofderful dogs will love the challenge of Divide-Twin Creek!
