"Discover the sharp features and technical moves of Nipples and Knobs, a one-pitch sport route on Pinnacles’ Flumes Formation. Expect vertical climbing with a slight overhang, protected by well-placed bolts, perfect for those refining their 5.10 skills amid striking Central Coast scenery."
Nipples and Knobs offers a compact yet compelling introduction to the sport climbing scene at Pinnacles National Park's Flumes Formation. This single-pitch route challenges climbers with a steady vertical ascent that shifts into a subtle overhang, carved over time into the volcanic rock by ancient flows and shifting earth. The route begins on the first pitch of Tilting Terrace before veering straight up past seven well-spaced bolts, each placed to protect the prominent holds and sculpted knobs that punctuate the wall. The rock feels alive beneath your fingers—the pimples and bulges ready to snag your grip or test your footwork as you push upward.
Despite its modest length of 60 feet, Nipples and Knobs packs plenty of character, demanding technical precision and confident movement on slightly overhanging terrain. The climb rewards the focused climber with a clear view of the rugged Pinnacles landscape, framed by the arid Central Coast sun and the dramatic sweep of the west-side cliffs. An optional bolt on a ledge near the base offers a secure spot for the belayer, ensuring steady support as you navigate the route’s subtle cruxes.
Planning your climb here calls for approach awareness: the trail to the Flumes is well-marked but crosses exposed sections where loose rock occasionally tests your footing. Lightweight shoes with sticky rubber work best, complemented by a harness setup suited to sport routes, including a 60-meter rope for safe rappels. Bringing plenty of water is vital, especially during the warmer months, as the midday sun quickly heats up the walls and surrounding talus.
Whether you’re stepping up from easier routes or aiming to polish your 5.10 technique, Nipples and Knobs provides a focused burst of climbing challenge balanced with accessibility and stellar natural panoramas. The bolted anchor and rappel chains make for a straightforward descent, and the route’s position near other popular sport climbs in the Flumes Formation offers the chance to build a varied day out in this unique volcanic terrain.
Loose rock along the approach trail requires caution, especially near the base where footing is less secure. The rappel anchor at the top is reliable but always double-check connections before descent. Avoid climbing under wet conditions, as volcanic rock can become slick.
