Sheep Mountain is not far from Helena. It offers mostly granite trad, but there are some sport and sport/trad lines as well.
Although Haystack Rock is a small crag and does not offer the tallest lines or what are considered the local classics, it is a nice spot for several reasons:
About 20-30 minutes south of Helena, take the Clancy exit from I-15. The directions on Mountain Project may mislead you because they say to take Lump Gulch Road west out of town when in fact you have to head north out of town on Main Street and then bear northwest until reaching Lump Gulch Road. (I hope the image below helps.)
After that, drive about three miles and turn right onto (signed) Sheep Mountain Road. Shortly after passing the main parking are, you will reach a three-way intersection. Turn right onto a dirt road and park in the small parking area. The crag is directly behind the parking area.
To reach the four sport routes, follow a use trail downhill on the left side of the crag. Here are the routes from left to right as you face the wall (note that you will reach them right to left):
It is easy to scramble up the crag to access three sets of hangars intended for use as toprope anchors (obviously, you need your own gear for this).
Closer to the parking area and almost opposite the sport routes listed above are some additional climbs. One is a short 5.8 crack that can go on gear and is served by one of the aforementioned sets of hangars. There also are some cracks in the 5.10 range and one 5.9-10 route that has some bolts but also takes gear. These other routes require gear anchors.
None other than obeying any posted regulations and respecting private property. No fees.
Spring through fall.
No campground. You can probably do dispersed camping here.
