“A mostly stunning trail leading to Thunder Mountain summit - with extra sections worth skipping.”— Michael Ahnemann
That most commonly traveled section climbs steadily to 9300 ft, and you'll feel you've gotten quite a workout. But the climbing is never brutal - just steady. The ascent has tons of scenery to keep you busy. You'll start climbing through forest, but along the way, you'll see hillsides covered in wildflowers, dramatic views of Two Sentinels (8780 ft peaks) and the dark volcanic north face of Thunder Mountain.
Continue up Thunder Mountain Spur Trail to the summit for spectacular 360-degree views.
You can tack on and additional section at the start, by starting further southwest on CA 88, at the true start of this trail, and you can continue further on this trail past the Thunder Mountain summit, but most agree that wouldn't be worth it.
