Bootjack Gap Trail is a 4.6-mile point-to-point backcountry route from remote Bootjack Gap Trailhead (3N3) to Bootjack Gap at Yellowstone’s eastern edge. It rises from about 7,600 to 9,200 feet, with roughly 1,700–1,800 feet of climbing. Allow about four hours for this segment. The mileage covers one direction only; this is a remote connector, not a loop or a roadside day hike.
The 3N3 trailhead has no road access, so the 4.6 miles do not include the approach or a return. A longer route from the Lamar River through Miller Creek reaches Bootjack Gap in about 11 miles; that figure belongs to the full approach, not this trail segment. Plan the connecting route and your exit on the current backcountry map before setting out.
This route reaches high, remote ground, so the climb, altitude and logistics matter more than the short mileage suggests. Yellowstone does not allow pets on hiking trails or in the backcountry. Overnight stays in the backcountry require a permit. Current route conditions and access details were not established here; check them before you go.
