We needed an overnight stay en route to the eastern Sierra and decided this spot would work. We knew we'd taking a risk for a one night stay on a Saturday without reservations but it was October 1 so what the heck. 

When we arrived there were several sites along the stunning Topaz Lake that appeared reserved for the weekend (F-Su) but were empty and a few that were open. We travel in a Class B van so typically will dry camp unless we have chore days.There were lots of sites in the primitive camping area but it was just a dirt parking lot with no shade (our propane fridge is cranky in heat so we needed shade). 

There was no staff on site. The only way to pay is via a kiosk but ONLY for day use and primitive sites. The only way to pay for the RV Hook Up sites (most without sewer at site) was via phone call (M-F) or online reservations. I had a weak Verizon signal and was able to reserve our spot for the night after a few attempts on the very funky county website. 

• If lucky enough to get a site, along the lake, you'll be rewarded with stunning views but it can get windy 
• Decent sized, level sites along the lake with lots of open space between campsite and lake
• Upgrades since past reviews must have happened recently as the bathroom floors and stalls appeared new. The central sewer dump concrete looks new as well and was working. All were were very clean. 
• Showers were working (and free) but didn't use so not sure about water temp. They were not updated but were clean. 
• This is a boaters' paradise and VERY loud during the day (and we were there off-season) Quiet at night. 

We'd probably pass on staying here again unless we were going to use the amenities (dump, showers, water refill) because it was pricey for just dry camping (unless in the primitive spots). We can do better at some  of the Forest Service campgrounds we saw along 395 for less money.
