This section of Trail 89 is one of the best sections of trail in the Black Hills. The first pitch known as Alkali Ridge is very popular as an out and back to the top of the ridge from Alkali Creek TH (for years people have mistaken this section as Bulldog which is actually the next section of trail to the southwest). This section of trail winds through the forest crossing several different geological strata. Expect flowing single track trail with reasonable climbs and descents. There are several short punchy climbs in the Bull Dog Creek area. The scenery is excellent.

Access Info

Park at either Alkali Creek Trail Head located east of I-90 at Exit 34 a half mile east on BLM Road or at Elk Creek Trail Head located on Runkle Road east of Vanocker Road.

       Rode from Elk Creek TH towards Alkali Creek TH but bailed at Rattle Snake Ride and came back to Elk Creek TH via the Dams area trails. IMO riding Elk Creek -> Alkali TH is the best direction.
