I've camped at Goat Meadow twice- once in 2022 and more recently in March of 2025. Both times were fantastic.
When you drive up to the snowplay area, continue straight off of the paved road (don't make the left) and you'll find a plethora of places to park and set up shop.
The elevation at the site is appx 5200, meaning it will get snow in the winter(ish) months. When I was there recently, some of the 'campsites' had 0-3", whereas other spots were about 6-8". Consequently, there were about 6-8 cars/vans that ended up camping in the parking lot of the snowplay area. I was the only one in the actual snow, which was great! I'm glad I didn't set up in the parking lot though, as around 7am, the place filled up with people sledding (as the area is intended to be used).
Couldn't recommend this place more. Coyotes and bears are active in the area- coyotes raided a bag I had hanging from a tree and stole my food!
