Trail Description

This trail is commonly used as access to Sphagnum Bog at Crater Springs (see related material to the right). Mountain hemlock and shasta red fir are the primary forest cover beginning at the park boundary.

Sphagnum Bog is a wet meadow (technically, a fen) filled with fragile bog dwelling plants. Use extreme care while traveling in this delicate ecosystem.

Trailhead location: From Prospect, OR, travel north on Highway 62 until reaching the junction with Highway 230. Continue on Highway 230 for 6 miles to the junction with Forest Service road 6530. Turn right on road 6530 and continue 1.3 miles to the second junction with loop road 6535. Follow road 6535 for approximately 5.3 miles to the trailhead on the left. The trail begins a slight upward climb to a gate on the upper end of road 6535. The trail continues beyond the gate for 0.5 mile before reaching the west boundary with Crater Lake National Park. A short distance inside the park, at the junction with the Bert Creek Trail, a sign reads Sphagnum Bog 1.7 miles.

Seasonal Information: Expect the trail to be covered in snow from October to early July, however, conditions vary somewhat from year to year. See Crater Lake Current Conditions for more information.
