Chad Shepard has helped us out with some info in regards Tuolumne Meadows, #1 in the Bouldering trend ranking. It is located 1.5 hours from Yosemite valley at 2,500 - 3,000 meters and the potential is endless.
"The past two summers, I see groups of 20-30 people at each spot every day over the weekend. It appears to be a 10 fold increase in traffic since the new guidebook came out 2014. There's 1200 problems in the Tuolumne guide. and about 300-400 problems not in there. Most of those are newer areas not in the guide, some just too far away. The guide covers an area of about 30 miles of road, and hiking as many miles away from the road as you like. Most of the bouldering on the guide is within 1 hour hike, but you could go farther and find as many new boulders as you want.
The climbing season is generally from June-September, and there is no access at all from November to May. The Tuolumne Meadows area is very large (it’s a much larger portion of Yosemite National Park than Yosemite Valley. You might drive 30 minutes and hike an hour to get to the next bouldering area.
One of main attractions of Tuolumne Meadows is the scenery. It’s in a designated wilderness area, so the landscape fairly wild. The granite domes and high alpine lakes and meadows make for a great backdrop for a day out bouldering. The different bouldering areas are as diverse as the rock quality.
It’s my hope that climbers will understand how fragile the high alpine environment is (many of the boulders are between 8000’-10,000’) and respect wilderness ethics as the bouldering traffic increases."
