The Fir, Spruce, and Aspen-lined Old Fall River Road is an ambitious launch point for Mount Chapin. The 6.9 miles you will walk on the historic Old Fall River Road to Chapin Pass is worth the distance, as it passes the Endovalley overlook (amongst others) and follows Chasm Falls in delightfully close proximity.
You may drive this 6.9 miles while the road is open to vehicles (~July 4 through late Fall).
The Chapin Pass trailhead sits modestly on the right side of the road and points you onto the Chapin Creek Trail. You are steered East toward Mount Chapin, then to the saddle between Mount Chapin and Mount Chiquita, and finally to the Mount Chapin summit; an easily followed trail up a rocky mountain and a characteristically rocky summit.
When you reach your reluctant (and it will be!) departure time, consider descending the East Ridge instead of back-tracking. Is it a steep and narrow slow-go? Yep. Is it a bush-whack? Yes. Will it give you the opportunity to descend a unique area through beautiful shrubbery while butt-scrambling over rock and past draining water? You bet!
