The O&W Rail Trail is a 27-mile recreational trail located in the Rondout Valley, from Kingston to Ellenville, NY. The trail is divided into four sections between one and 14 miles long, connected by approximately 7 miles of road. It follows the course of the New York, Ontario and Western Railway which was decommissioned in 1957.
 

This route begins at the Freedom Rock in Adel and heads East. The route includes the entirety of the trail (minus the Jefferson out/back) and includes a diversion from the trail due to the 2020 construction between Redfield and Adel. The diversion does continue on a gravel road that runs parallel to the trail for the entire final 10 miles.
(Editor's Note: when the trail is re-opened, the Route should be adjusted to eliminate the road section).

Der Karwendel Höhenweg führt durch den südlichen Teil des Karwendelgebirges in Tirol. Einzigartig ist dabei der mehrfache Blickwechsel zwischen der Einsamkeit der Karwendel-Wildnis und dem geschäftigen Treiben im Inntal. Man startet den Weitwanderweg vom Seefelder Plateau durch Wald und über Almflächen ins Hochgebirge, wo man Gamsbeobachtungen beinahe garantieren kann.

Following the original historic Colorado mining route on Gold Camp Road from Victor, CO to the junction of High Drive + Gold Camp within Colorado Springs, CO city limits. 

Route is entirely on dirt roads which once were a highly used railroad and passes through various original mining tunnels and rock formations cut by hand and explosive devices to make way for train traffic in order to transport mined goods from Cripple Creek/Victor to the city hub of Colorado Springs.
