Visiting from Chapman Inn
Distance, bearing & drive time
Chapman Inn sits 25.6 miles west-southwest (bearing WSW) of Jefferson Ravine. At moderate back-road speeds the drive runs about 44 minutes — comfortably inside a half-day outing window after breakfast.
Best time to visit
Late May through October; avoid black-fly peak in late May. Being this far north (lat 44.304°), first snows typically arrive by mid-October and linger into early May — narrow the window accordingly. At 25.6 miles from the Inn, block the full day — sunrise start, late return, packed meals. Conditions at Jefferson Ravine track the nearby Chandler Brook stream (0.4 mi away) closely — if that is runnable, so is this.
