Hikers say
…the maintained Quarry Trail becomes unmaintained and requires scrambling for the last 500 feet to the tiki-rock summit, with loose footing and poison oak in the boulder sections — but 360-degree views of Morro Rock, Montana de Oro, and the Santa Lucia Mountains are widely called worth the effort.
Nine Sisters summit (911 ft), ocean panorama, Morro Bay harbor, Tiki Rock.

10.8 mi1,325 ft gainOut-and-backBest: Oct–May
Hikers say
…the new route is very gradual and mountain-bike-oriented with switchbacks that feel slow for hikers — panoramic views over the Irish Hills and inland canyons rather than the ocean-facing drama of Valencia Peak, with low foot traffic.
Big-sky backcountry, fewer people than Valencia, remote feel.

Hikers say
…it's 4.5 miles and almost fully exposed with no shade, but the 360-degree view from the pyramid-shaped 1,275-foot summit — ocean south to Point Buchon, Morro Rock to the north, green hills in all directions in spring — is one of the best in SLO County.
1,347-ft summit, 360° ocean panorama, Morro Rock view, wildflowers.
