Yet another of the smaller geyser/hot spring areas, biscuit basin has different character than black sand basin down the road. Sapphire Pool is gorgeous and there were some other deep blue beautiful hot springs here.
The parking area is small and if I recall correctly, there is no restroom or pit toilet, which surprised me at an attraction of this size. Even mud volcano on the other side of the park had facilities.
I'm going down a bit of a rabbithole here, but it seemed the east side of the park in general had more facilities (restrooms) than the west side. I wonder if it's because a pit toilet isn't possible on the thin crust of the west side in some places.
Anyway, pee ahead of time, and then enjoy this as it is well worth a visit.
