So onsen will be the two public ones for guests I'm guessing. Both seem to be indoor ones (one cypress and one rock) and I would guess they alternate between male and female onsen day by day like IC Beppu does for the two (bigger) Onsen?
They do indeed alternate the sides, there are also rotenburo in the public area.
