These are bouldering areas along the Caves Trail, from the east end, to the Caves. I collected these notes combined from Char Fetterolf's and Rob Holzmann's published guides, searches online, combined with hiking the area before I started climbing. Unfortunately I moved out of state before I had a chance to do my tour of Haycock, so I hope others will chime in with notes to improve these descriptions.
Park at the Top Rock lot, and follow Top Rock Trail to where the Caves trail connects on the left, at the Bubbler and Before the Storm. Follow the Caves trail; continuing straight would take you to Teddy Bear and Top Rock instead.
You'll reach bouldering areas from this end of the Caves Trail in this order.
(each of the boulders listed below should be added as a subarea of the Caves Trail East when someone has the chance to visit, climb and document them here)
Before the Storm
Hike a few minutes past here; a right-hand trail goes uphill to the Gateway area.
A minute or two past the junction, you reach the Tooth.
A few minutes past the Tooth, another right-hand trail goes uphill to the Gateway area (to Bootleg). Then immediately are three more established boulders.
A few more minutes of trail between Three Seams and the Cracked Egg.
The Cracked Egg
A few minutes past the Tooth, a right-hand trail goes uphill to the Rocking Chair and Gustapo.
The Rocking Chair area
After the Rocking Chair/Gustapo turnoff, the trail reaches the Caves in a couple of minutes.
Follow the trail from Top Rock towards the Caves from the east, or from Hangar 18 to the Caves from the west.
