This is a nice site with lots of shade. There is a lovely hiking trail at the far end of the site. There is water, flush toilets, fire pits, and picnic tables. It is a short walk to Lake Arrowhead. This is a dog friendly site. Sadly the sites are small with no space between the sites. The noise restrictions after 10pm are not enforced so bring ear plugs. Expect a lot of people walking through your site.
It sounds like there are multiple Big Meadow camp grounds in California. This review is for Big Meadow Campground, Sequoia NF - FS, CA. The photos are of site 009B. My visit was wonderful. The camp sites are large. We set up two 8 person tents and one 2 person tent and there was plenty of room for more. The firepits are very well made. They block the wind while allowing good airflow. There is a very large picnick table at each site, a bear box, and plenty of shade. There is a vault toilet that is cleaned daily. The sites boarder a stream. The water level is about 3 inches in July with temperatures in the 80's. This is a dog friendly site. There is no potable water at this site.
