The trailhead for the Boundary Springs Trail is located at a pullout on Highway 230 near milepost 19, about 5 miles west of Highway 138.
The trail is an easy-to-moderate run near to the headwaters of the Rogue River. The trail is fairly flat, and after leaving the trailhead parking lot, you'll pass through a forest of shasta red fir, lodgepole pine, and mountain hemlock. Just under a mile you'll come to the junction with the Upper Rogue River Trail and at a mile, the trail intersects a forest service road. Turn right and head up the road for about 100 feet before turning left, back onto the Boundary Springs Trail.
The trail then follows the narrow Rogue River canyon until it ends at a wet meadow fed by the Boundary Springs. An interesting note is that snowmelt, not Crater Lake, is the source of Boundary Springs water. Boundary Springs on the north forms the headwaters of the Rogue River.
Boundary Springs ends at the Bald Crater Loop Trail
where you can choose to continue your run or turn around and head back the way you came. It should be noted that you can also reach Boundary Springs Trail through the park via a southern trail that connects with the Bald Crater Loop Trail
, but this will make for a longer run.
