up by wilderness vilage, by rocky mountain house, there are good trails. at wilderness village(a campground) they should be able to tell u about where the trails are. and in rocky they can tell u where wildernes village is.
(if u head to wilderness from rocky go pass wilderness village and then u will come to a spot where u can continue on the road or turn left.
u turn left and go about halfway down the road and along the right u will usually see trucks parked with there bike trailers. if u dont see them then look for a sandy hill it will be obvious the dirtbikes were there.
people from the area will be able to tell more specific directions. )
hope this helps
