I stayed in the City of Puerto Princesa while in Palawan. I used that as my base. Going to the underground river, I have to take a car to Sabang Village by Sabang bay, rent a boat to go to St. Pauls Bay where you disembark and walk to a river inlet, where tour boats to the subterrenean river are located. This photo is Sabang Bay with one of our tour companions negotiating for a lower rental fee of the boat. It was a gorgeous day and though the sea is choppy but it turned rough at about 1:00 PM and wind starts to blow harder.
