I now have come to understand that trails marked as bycicle routes are gravely roads–not very enticing hiking trails.
The route back is the winner here. If you had enough time to stretch this 10 miler into a beach afternoon before your return all the better. (Though if the beach is what your after, skip to the hostel or further and you’ll bypass hours of hiking and lots of incline on the way out.)
What next? Instead of this route, what about: Limantour > Sky > Woodward Valley Firelane > Sky. 9.5 miles and fire lane up-and-out will be quieter and more challenging then Woodward out(?).
