Proud center of fortress
Study the map. Study the map some more. Look it over one more time. The Sierra Club lists this hike as 8-10 miles roundtrip. No clue on what they're doing but I assure you there's a shorter way. Best if you are really good with difficult terrain.
The area is precious and full of adventure. No witches or modern apaches in tennis shoes with machetes. Just a zoo of snakes and enough tarantulas for any enthusiast!

This is a more difficult hike. It would be unwise to attempt this without prior experience hiking.
