Directions to Great Wall

Muir Valley
This wall is in property owned by Muir Valley. Be respectful.
If traveling from the Indy Wall, continue hiking left past the the Hideout and around the corner for about 5 minutes until you see the next bolted line which will be "La Escalada". There is another approach that leads directly to the Great Wall and bypasses the initial walkup to the Sanctuary/Indy Wall area. From the parking area, follow the main road down a large hill which curves sharply to the right near the bottom. After the curve, continue along the road for about 100 feet until you see another road branch off back to the northwest (left). Follow that road about 100 feet to a creek crossing and continue along a grassy road for about 5 minutes keeping the creek to your left. When the road turns sharply to the right, continue a few minutes longer until you see two wooden signs on a tree pointing to The Solarium and The Great Wall near an obvious stream crossing on the right. To reach The Great Wall, turn right and cross the stream then continue through a swampy area (with boardwalks) along the trail as it winds uphill to the wall. Routes are listed from left to right.

downrating every route on this wall by two letter grades would benefit new climbers appreciation of historical grading norms.

yeah but it would pretty much derail the New Climber Coddling Mandate (NCCM) set forth in section 6.23e of the much-maligned Americans for a Softer Future Program.

I would take a grade or 2 off everything at this wall. Except for Buccaneer. All the climbs are awesome though.
