Not bad. I started at 7 am and there were just 2 other cars in the parking lot. When I finished the parking lot was full, but I didn't see a lot of people on the trails. The other areas you could park were pretty empty.
The one annoying moment was when I stepped aside on the trail to let a group of 5 pass and 2 of them decided that was a great time to pull out their phones and take pictures of the woods.
Grrr. That would be annoying without a pandemic.
