Before heading out, make sure your rack suits mid-to-hard sport climbs, and prepare for technical sequences that demand finger strength and precision. Although the rock is secure, always assess anchors and be ready for the physical demands of climbing in this vertical playground. Riverside Quarry’s Taboo Area rewards persistence and skill with routes that leave an impression long after the day’s send.
While the rock is solid, climbers should maintain awareness on steep corners and arched faces where falls can be awkward. Double-check your anchor points and be cautious approaching the routes, as the Quarry can have loose rock in approach areas. Seasonal heat means hydration is critical to safely navigating climbs here.
Approach the right side of the west face of the Quarry to find the Taboo routes easily.
Start early or climb later in the day during summer to avoid peak heat.
Bring plenty of water and sunscreen, as the steep walls give limited shade in midday sun.
Check your gear before each climb; although bolts are solid, some anchors could use assessment.
Routes in the Taboo Area primarily require sport climbing gear with well-placed bolts. A standard sport rack suffices, but climbers should be prepared for steep moves on sustained difficulties.
