We parked at the end of Primos Rd. and took NFS Non-Motorized Road 233.1 for about a mile out and a mile back (this connects to many other "trails" on the online map look like they are non-maintained roads?). We were the only ones on the trail although we saw lots of evidence of other hikers, and dog tracks (and poop). The trail follows Gordon Creek which looked mostly frozen, but there were some open water spots where quite a few American Robins were congregating. I also spotted my first Golden Crowned Kinglets, a pair, flitting around on a tree right on the trail.
My eBird checklist.
