Day Glow at Radon Pinnacle: A Sharp Sport Climb in the San Bernardino Mountains

Day Glow offers a concise yet engaging climbing experience that carves through the steely granite of Radon Pinnacle, perched within the rugged outline of the San Bernardino Mountains. This single-pitch sport route, stretching approximately 50 feet, demands precision and a steady hand from start to finish. The climb begins within a sheltered alcove where climbers find thin holds that test finger strength and technique. A quick mantle past the opening bolt transitions you onto a ledge that acts as a brief waystation before the real challenge unfolds. Here, the head wall juts steeply, playing with varied and distinctive features that call for a mix of delicate moves and confident body positioning.

This route rewards well-prepared climbers with a rhythm of tension and release. The spacing of six fixed bolts ensures a secure ascent, yet the absence of chains at the anchor means careful attention is required while setting up for descent. The granite’s texture lends itself to precise footwork, making it an excellent climb for those refining their sport technique or seeking a focused challenge close to Lake Arrowhead.

Accessing Radon Pinnacle is straightforward but demands respect for the natural environment. The climb’s area offers panoramic views that stretch over caressing forested ridges and rugged summits. Its east-facing orientation captures morning sun, warming the rock early and offering cooler shade in the afternoon—ideal for timing your climb to avoid midday heat. The route's moderate length suits those looking for a concentrated burst of climbing intensity without a long approach or descent.

Practical gear includes a standard sport rack with quickdraws, a harness, helmet, and climbing shoes geared for edging on smaller features. The approach trail is well-defined yet can be rocky underfoot, so steady footwear is essential. Hydration and sun protection remain vital, especially during the warmer seasons when the sun lingers on this mountain ridge.

Day Glow captures the essence of climbing in the San Bernardino Mountains: raw, straightforward, and richly rewarding. It's a climb that invites engagement without overwhelming, blending athletic rigor with the quiet majesty of its high desert surroundings. Whether you're polishing your 5.10 skills or seeking a dynamic, accessible route near Lake Arrowhead, Day Glow provides both challenge and charm in a compact package.

Climber Safety

Watch your footing on the approach trail—rocky and uneven sections can challenge your balance. At the top, the anchor lacks chains, so ensure your rappel setup is solid and double-checked to avoid slippage.

Local Tips

Arrive early to benefit from the morning sun warming the east-facing wall.

Wear shoes with solid edging ability for the fine foot features.

Pack plenty of water—the dry mountain air is deceptively dehydrating.

Be cautious at the anchor; the bolt anchors have no chains for rappel, so secure your anchor carefully.

Route Rating

Difficulty
5.10a
Quality
Consensus:At 5.10a, Day Glow sits in the moderate range but offers a sustained sequence that can feel pumpy due to the thin holds and steep angle. The moves on the head wall provide a crux with delicate balance rather than raw power, making it a solid test for climbers stepping up from easier 5.9s. Compared to nearby routes, it holds its own for technical finesse rather than sheer difficulty.

Gear Requirements

Six bolts protect the climb evenly spaced, leading to a bolt anchor without chains. Bring at least six quickdraws and prepare for delicate clips on thin holds.
