Well known and traveled trail to Ben Lomond and Willard Peak.  Great wide trail with a couple steeper loose area. 

A 22 mile paved trail that use to be a railroad route between Kila Montana and Somers, Montana. It is now a great trail for walkers, joggers, bikers, and such. It does travel through part of Kalispell, Montana as well.  

A nice long hike/climb from Saas Fee on normal route to Nadelhorn via Mischabel hut. Technically not difficult but can be tricky with ice on flanks. Nice snow ridge and rock ridge on top (grade II). Some steep ice at the way to Windjoch. 

The Véloroute des Bleuets is a cycling path that loops around the Lac St-Jean, passing through 16 villages and small cities. The path is mostly asphalt, sometimes on the shoulder of the road, sometimes going through the woods, sometimes alongside the road with a median strip. There's a 20km going through the provincial park SEPAQ Pointe-Taillon, a flat non-technical dirt road. This is the only section non-accessible by vehicule, if you're going supported. On the Véloroute des Bleuets website, there's options for ferries that make the route shorter.

The route begins where the AT meets Shook Branch Road at Boots Off Hostel in Hampton, TN and goes to the iconic arch in the Damascus, VA city park. 2023 data book has the start and end points as NOBO mile markers 428.8-470.4. The route can be attempted NOBO or SOBO. Best I am aware, this has been a challenge to hikers from the staff at Boots Off Hostel, going back to at least 2019 if not further back. This is 40+ miles of classic Appalachian Trail single-track.
