At the Lower Irish Boulders, you find yourself stepping onto fresh, solid stone that’s been quietly gaining attention among both casual boulderers and dedicated project seekers in the Conejo region. This collection of climbs provides something for everyone, from bold off-the-deck highball problems demanding commitment to technical challenges that test strength and precision, like the well-loved projects that anchor this area’s reputation.

Getting to the Lower Irish Boulders requires a bit of care and attention to detail. The trail is subtle and easily missed by those unfamiliar with the terrain. Heading past the south side of the main rope climbing section—near Pamela 5.6—you'll find yourself at a fork where many bear right towards well-trod paths leading to the 24 Boulders and the powerline trail toward Upper Irish. Instead of turning right, keep walking toward the freeway side, where you’ll spot a steep, slippery descent about 30 yards long that drops you directly into the heart of this bouldering enclave. Alternatively, for newcomers, a gentler approach involves warming up at Upper Irish Boulders before walking downhill past notable routes like Thriller and exiting by the same trail used to arrive.

The vibe throughout Lower Irish maintains a refreshing blend of challenge and accessibility. While the rocks call for focused effort—especially on problems with a harder edge like the project climbs—the area is also welcoming to those warming up or looking to spend a relaxed afternoon fine-tuning technique. Noteworthy classics pepper the zone, including Three Wise Men (V0) and Esperando la Tormenta (V2), both boasting high user ratings for their engagement and quality. Sitting Bull (V3) provides a step up in difficulty, demanding more from climbers but delivering a satisfying push for those ready to test their limits.

Elevation here settles around 873 feet, providing a comfortable altitude for most climbers, while the setting near Conejo Mountain offers sweeping views that enhance the climbing experience without the crowds found at better-known spots. Since the trailhead near the powerlines was closed due to safety concerns—an unfortunate incident involving electrocution—the current access route involves parking nearby and hiking through a residential area. While this approach has so far remained incident-free, climbers are urged to remain respectful and discreet, avoiding disturbance to residents and heeding any no-trespassing signs.

The rock quality is consistently fresh and solid, but approach terrain calls for reliable shoes due to the slick, sometimes slippery footing on the descent path. Weather conditions in this part of California favor all-year climbing, though late fall through early spring tends to provide the most predictable dry and cool days, making these months prime for visits. Climbing in the heat of summer may bring direct sun exposure with limited shade, so starting early or late in the day is advisable.

Lower Irish Boulders sits within the Conejo Boulders region, which draws admiration for its variety and relaxed, low-key atmosphere. Although the route count is modest, the area’s appeal emerges from quality over quantity. Climbers often appreciate that it feels more like discovery and exploration than ticking boxes. Pads are essential here given the height and variety of problems, and the general terrain welcomes both sport climbers seeking a supplement to their rope climbs and boulderers wanting to explore raw and engaging stone at their own pace.

If you’re planning a visit, come prepared with sufficient crash pads, a brush to clean holds, and a keen eye for respect—both to the environment and the local community. The Lower Irish Boulders invites you not just to climb, but to experience a quieter side of Conejo’s granite that rewards persistence and offers a well-rounded day out in a rugged, intimate setting.
