There are 5 total. The first 3 are simple and have fires right next to them.
The last 2 are next to the checkpoint but tricky to get to, since you can't carry fire through the waterfalls. Grab fie from the checkpoint and drop down, using fire jump to avoid hitting the pool below.
Sneak around the archer on the left and throw fire at the sulphur.
Since it blows up without any flames, you'll probably have to go back and get another fire from the checkpoint.
