Excellent bouldering is found here. There are also a couple short top ropes. The main area lies below a House known as "Stonehenge". It can be rented for several hundred a night. Be careful not to disturb anyone at the house and don't park in front of it.
Space Invaders is a huge, north facing, overhanging boulder nearby. The climbing is in the 5.11 to 5.12 range. The routes can be led or easily top-roped.
There are two micro domes (the "Space Domes") across the gully to the northwest of Space Invaders that offer short, challenging routes. Use Space Invaders approach, but head up and left to the domes.
Echo View Estates is about two miles from the junction of Sawmill Rd. and Hwy 50. Take the first right, onto Twin Peaks. Park at a dead end just beyond Mountain Canary. Do not disturb the residents. Hike up a gully and the cliff is on the right.
