We'll hike Movie Trail to the base of the Prow using GPS waypoints which have been successful in the past. (I tried this last year and turned around when the trail disappeared.) It should take 3-4 hours and will include a lot of bushwhacking, starting about 6800' and going to 8400'.
We will start at 9a from the Piedra Lisa parking lot - on FR 333 beyond the turnoff for La Luz after it turns into a dirt road. There are no bathrooms at the parking lot and there's a $3 parking fee payable at the kiosk as soon as you turn off Tramway (you don't need to pay if you have an annual pass). Bring water, a snack and recommend you dress in layers. We'll stop for a snack at the turn-around point.
