The trail begins at the Chatter Creek Trail sign on the northwest side of the parking lot. At first, the dirt trail is flat, hugged by vine maple that turns crimson in the fall. The initial incline is mild and rolling, lulling you into a sense of gentle exertion. Throughout portions of the trail, expect it to be brushy and almost overgrown at times. At 1 mile, cross a footbridge over Chatter Creek.
With this warm-up section behind you, the trail begins to climb more steeply, averaging a 20% grade over the next mile. At 1.2 miles, cross into the Alpine Lakes Wilderness. The trail is mostly dirt with some rocky sections.
At 2.3 miles, there is a water source and at least four forested backcountry campsites. Between August and September, this could be the last reliable water source until you’re almost done climbing to the pass. A seasonal water source is available at 2.6 miles. Another viable campsite is located at 3 miles, but there is no water without a walk.
The views begin to open up as you climb out of the dense forest. A seasonal water source may be available at 3.8 miles. The trail gives you a break with a lower grade, showcasing views of the basin below Grindstone Mountain. Soon, you will be looking down on the area you’re traversing.
The next mile rises another 1,300 feet as you ascend to the pass. The trail can be very rocky and steep, with almost no shade. When you stop to catch your breath, listen for pikas chirping from the boulder fields. Near the pass, at about 4.8 miles, find a seasonal water source on the left of the trail, and a small, exposed campsite on the right.
Reach the pass and take in the views. At this point, you’ve climbed about 4000 feet in 5 miles. The views here are expansive, so if you’ve had your fill, this is a reasonable turnaround point. You may choose to extend your trip to view the golden larches or Lake Edna. If so, continue northwest over the pass. Be aware that even in early fall, there can be ice and snow on this side of the pass as it is shaded the entire day.
After a short descent, the trail heads left, winding around large boulders. If there is snow, the trail can be easy to lose. There are small streams throughout the area. At 5.7 miles, reach the end of the Chatter Creek Trail as it joins with the Icicle Ridge Trail. From here, you can turn around, or continue on to Lake Edna and beyond.
