Full disclosure: I didn't camp here as I passed through this area en route to another dispersed campsite a bit deeper in. That said, we stopped here for a snack / water break and to filter some water so I had some time to explore.
The area is BEAUTIFUL. The lake is stunning, and sits nestled right up against some pretty dramatic mountains. Lots of trees and dispersed camping sites throughout. The hike in is about 7 miles, very gentle incline. Not too hard unless you're not used to carrying weight.
When we went through, there were people camping, but not too many. Once we went beyond this camp area, we didn't see a soul. That's likely because of the really intense pass you have to go over to get to the dispersed site we were aiming for (see my review for that here: https://thedyrt.com/camping/undefined/flower-lake-dispersed-camping).
Tons of great hiking in this area as it is close to the Continental Divide Trail. A lot of it definitely involves going up the sides of mountains, but if you're day-hiking and not carrying a heavy backpacking pack, they're not that hard.
Bring bear spray. Hang your food. This is grizzly country.
For true back-country seclusion you'll probably want to go further in than this dispersed area, but for a less strenuous and equally as beautiful locale, this is a pretty amazing place.
