My partner and I hiked this as a post-work hike on Friday, arriving around 5:30pm to 10 or so cars parked in the lot. There is one massive pothole just after the bridge to the Garfield Ledges trailhead and we scraped the bottom of our VW Golf just a lil bit, but otherwise the road is smooth sailing (if you're nervous about it, there is some room to park just before the bridge, you'd just need to add in a bit of extra road hiking).
We passed a few groups headed back to the trailhead but otherwise had the trail to ourselves! The trail was in great shape the entire way, with just a few downed trees here and there. As others have mentioned, the snow starts about a quarter mile from the lake. There are plenty of footsteps to follow. Since we arrived at the lake so late in the day (just after 8pm) the snow was pretty wet n' wild and I did appreciate having my trekking poles for stability.
There was one other group already set up for the night when we arrived, and thankfully, two tentsites melted out for camping (though I had been making mental notes of tentsites along the way had everything been full).
Heading out the next morning, we passed what felt like a lot of hikers, bikers, trail runners and backpackers headed in. But even so, there were quite a few parking spaces open when we got back to our car before noon.
