Short road to get to the Eaton Lake Trailhead. There is a small waterbar to get on this road from the Silver Skagit FSR. It was just big enough for me to slightly scrape my mudflaps on my lowered car so anything with more than 3" of ground clearance will be just fine. If you don't, there is a pullout to park on the Skagit FSR and walk up. Plenty of parking at the trailhead, along with a few campsites.
