We rode our mountain bikes from the Mailbox Peak trail-head up the
Granite Creek Road-Trail, we walked more than rode after crossing
Granite Creek because the Granite Creek Road-Trail gets steeper after that point. We
stashed our bikes behind the berm where the Granite Creek Road-Trail splits left to go up
Zorro Ridge (point 4642) and right to go up point 5124. We hiked to
trail 1009A and took the trail (which is well maintained) to the ridge
that separates the Granite Lakes and Thompson Lake, we then headed
north up the ridge toward point 5124. The ridge is easy hiking with
some pushing through young conifers. There is a nice log cabin near
the top of point 5124 with doors and windows 10 feet off the ground.
The top of point 5124 has excellent views. From point 5124 we headed
northwest across the ridge to point 4642, this is a beautiful narrow
ridge, there was some pushing through brush but it's not bad at all.
From point 4642 we descended west on the logging road, which has a few
thick alder patches but is mostly clear, I like this road. The bike
ride back to the Mailbox Peak trail-head was great fun, especially the
bumpy and steep first couple miles.
