From Bend head South on 97. At the sunriver junction there is a flashing yellow. If you turn left and go about 1/4 mile you will find a gravel pit on your right. Pull into the pit (great place for shooting trap and .22's) keep to the right and go around the pit and follow the trail around and around to the top of this little volcano. If you can get here just before sunrise I promise you the best view for miles.
This was around x-mas in my D-90, but still a beautiful place.
