Yo-yo hike (out-and-back thru)

In long-distance hiking communities, a yo-yo hike refers to completing a full route in one direction and then hiking the same route back in the opposite direction, typically as one extended journey. For example, a hiker might walk from the southern terminus of a trail to the northern terminus, then immediately reverse course and return to the start.

A yo-yo can approximately double the distance of an already lengthy route, making it a substantial undertaking. Hikers who pursue this style of trip typically consider timing, weather, and resupply patterns in both directions, since conditions encountered on the return may differ from those on the initial pass.

Repeating a trail in the opposite direction can change how it feels. Climbs and descents trade places, familiar campsites reappear in reverse order, and landmarks are seen from new vantage points. Some hikers enjoy this deeper familiarity, while others prefer new terrain.

The term yo-yo is descriptive rather than official. There is no formal body that defines precisely which variations qualify. Hikers and communities may apply the word differently depending on local norms and expectations, while recognizing that each long trip remains a personal undertaking.
