This route was planned by komoot.
This trail is considered difficult or even most difficult, suitable for experienced hikers. Expect significant elevation gain, steep climbs, and rugged terrain. Sections beyond Lower Silvis Lake can be less defined and more challenging.
The terrain is rugged and varied. You'll encounter steep climbs, wet and rocky sections, especially after rain. Beyond Lower Silvis Lake, the path becomes more 'off-road' with minimal tread and can be poorly marked, requiring good navigation skills. Snow can persist at higher elevations well into the summer.
The trail offers spectacular alpine scenery. You'll pass by Lower Silvis Lake and Upper Silvis Lake, and as you ascend, you'll get vast vistas of George Inlet and beautiful alpine meadows. The summit of Mahoney Mountain provides panoramic views.
The area is known for wildlife viewing. Keep an eye out for mountain goats, bald eagles, black bears, and deer. Always maintain a safe distance and do not disturb any animals you encounter.
The best time to hike is typically during the summer months, though snow can persist at higher elevations well into summer. Weather conditions in Alaska are unpredictable and can change rapidly, so always be prepared for varying conditions.
Specific parking details for the Mahoney Mountain trailhead are not provided, but access points are generally available for trails connecting to the Deer Mountain National Recreation Trail system in the Ketchikan Gateway area.
This trail is located within the Tongass National Forest. While general entrance to the forest is typically free, some specific recreation sites or activities might require permits or fees. It's advisable to check the official USDA Forest Service website for the Tongass National Forest for the most current information regarding any required permits or fees for this specific trail. You can find more information at usda.gov.
While many trails in national forests are dog-friendly, specific regulations can vary. It's best to check with the Tongass National Forest service directly regarding leash laws and any restrictions for dogs on this particular trail to ensure compliance and safety for your pet and wildlife.

Yes, both Lower Silvis Lake and Upper Silvis Lake are often dammed and contribute to the city's water supply, in addition to offering scenic beauty for hikers.
