Located in the famous Black Hills of South Dakota, Sylvan Peak is only about 4 air-miles west of the state highpoint at Harney Peak, and itself is the highpoint of Custer County. A thickly-forested peak, the summit ridge features many gigantic stone spires and cliffs, which make for interesting views and some hiking challenges, although the usual route to the top requires nothing more than simple scrambling at worst.

The usual hiking route is fairly short - maybe a mile and a half one way, but the last half is through poorly-blazed forest and requires attention to detail to stay on route. In 2004 I experienced a section of downed trees which occluded the route and eventually 'helped' me get lost for one of the very few occasions ever in my life!

Sylvan Peak is not heavily advertised and probably does not see more than a handful of visitors per year, mainly county highpoint enthusiasts. Views of Harney Peak from the summit are outstanding.

Getting There

The trailhead is at a pullout and gate along highway SD-87 about a mile north of the junction with SD-89, the road one normally takes to Harney Peak. The pullout is about 0.5 mile south of a short tunnel and will be on the west side of the road. There is room for maybe 2 vehicles; be sure to park so that you do not block the gate.

If coming from Custer, head north on SD-89 about 6 miles to the 89/87 junction. Go left onto SD-87 and about another mile to the pullout, on your left.

If coming from the US-16/SD-87 junction (i.e. from the Crazy Horse and Rushmore Monuments), go south on SD-87 about 5 miles to the pullout. Steep switchbacks occur at about 3.5 miles, and the short tunnel is passed at about 4.5 miles.

Red Tape

No fees nor permits are required. There are no signs prohibiting access at the gate. It appears public access is allowed, just not promoted.

When To Climb

The winter snows may make the roads impassable (not sure how often these roads are plowed), and the route messy. The best time seems to be from April to about October. Summer can get quite hot. Beware of thunderstorms.

Camping

Camping can be found near Harney Peak and Sylvan Lake. The whole Black Hills has many camping areas and many cheap hotels in Rapid City/Hot Springs/Sturgis.
