Worlds End State Park is in a narrow S-shaped valley of the Loyalsock Creek just south of Forksville, Sullivan County. Loyalsock Canyon Vista, reached via Mineral Spring and Cold Run roads, provides outstanding views, especially during fall foliage.
Who writes the descriptions of these trails? Loyalsock is a 59.2 mile trail, point to point. There is a loop option that is 22.9 miles. I have done the entire loop and about 15-20 miles of the thru hike on top of that, spent 6 nights and 7 days exploring the trail. It's absolutely gorgeous. They have so many primitive campsite setups with awesome fire pits and seats made out of rocks or stones.
So many different terrains it's unbelievable. Waterfalls, rivers, ponds, mossy areas, piney areas! This hike will kick your ass and take your breath away. Probably one of the best, most challenging options in the entire tri-state area. I would have gone crazy this summer had I not found this hike, as I am from the Canadian Rockies, and really missed the satisfaction of conquering mountains, and solitude the forest offers.
I remember doing this hike years ago when I was a Girl Scout at nearby Camp Lycogis. It follows the Loyalsock Trail for a good section of the trail, which has been rerouted. When I researched this trail it was telling me it was less than 3 miles. Since the trail was rerouted it was about 4.75 miles out and back, not a loop. Many parts of the trail are headed straight up the mountain, so it can be rather strenuous. When I went the water flow was low, so there wasn't much to see at the falls. Be careful at the top, it can get slippery and a fall would likely be the end of you. Even if the water isn't flowing, it's still a beautiful hike. The trail is very well blazed.
