A birthday tradition of sorts — another out-and-back to Eagle Peak, this time in early December with a heavy, moody sky hanging over the ridge most of the way up. The low winter sun kept breaking through gaps in the clouds just enough to light up the dry hillsides in patches, giving the whole climb a much more dramatic feel than the clear-sky versions of this hike.

The late-fall grass had gone that deep gold color that only shows up for a few weeks a year, with a rust-red outcrop catching the last of the afternoon light not far below the summit. A good, quiet way to spend part of a birthday — same familiar climb through Mitchell Canyon, but the weather made it feel like a completely different mountain than the last few visits.

Eagle Peak's summit marker, planted right at the exact 2,369-foot high point, made for the obvious spot to stop and take stock of another year — a solid, simple way to celebrate.

A nice Memorial Day version of this same out-and-back, over two years after the first — a straightforward climb up to Eagle Peak and back with no multi-peak loop attached.

Coming up through the chaparral in the late-May heat, the golden hills of the Central Valley opened up to the east, with the ridge dropping steeply into a shadowed canyon on one side and yellow-flowering brush lighting up the foreground on the other. It's a hike that rewards a slower pace — plenty of spots along the ridge to stop, catch your breath, and take in the view before pushing on to the top. The summit marker post, stamped with Eagle Peak's exact 2,369-foot elevation, makes for the obvious place to stop and take it all in.

A good, simple way to spend part of a holiday — nothing epic, just a solid climb to a peak I keep coming back to.

Another out-and-back to Eagle Peak, over a year after the first — same clean climb through Mitchell Canyon with no multi-peak loop attached. Spring had the hillsides green and lush rather than the dry gold of the summer version, and low clouds were pouring through the ridgeline below the summit for most of the climb.

A break in the clouds right near the top let a shaft of sunlight through onto the ridge, backlighting a lone manzanita and turning its bark that deep, almost glowing red the plant is known for. That kind of shifting, moody light is one of the best reasons to hike this peak in spring instead of waiting for the reliably clear summer days.

A quiet, atmospheric version of a hike I keep coming back to — sometimes the weather makes the same trail feel brand new.

A quieter, out-and-back version of one of my favorite Diablo summits — no multi-peak loop this time, just a January climb up to Eagle Peak and back down through Mitchell Canyon. Eagle Peak's summit is one of the more remote-feeling spots in the park, a narrow rocky ridge with no road anywhere near it, which makes it a nice contrast to Diablo's main summit just across the way.

Winter light on the chaparral gave the whole climb a different character than the drier late-spring and summer versions of this hike — cooler air, softer color on the hillsides, and a lot more solitude on the trail. The last push up to the summit ridge is steep and rocky regardless of the season, but the payoff is the same every time: a narrow rock spine with views dropping away into the shadowed canyons on one side and out toward the golden Diablo foothills on the other.

A good, simple way to spend part of a January day — nothing epic, just a solid climb to a peak I'd keep coming back to.
