You need to take a boat ride from sabang beach (you will get wet getting up and down the boat) to the underground river beach front. At the mouth of the cave, you get into smaller paddle boat for 4-8 pax and your 30-40mins began. It's very dark inside and you can only see where the paddler shine his touchlight. It doesn't have the colours of nature, just dark caves and rocks formation.
Aim to reach sabang beach by 9am to avoid the crowd of tourist. When I leave at 10am after the tour, I can see many boats entering the caves, meaning you will see a lot of flashlight shining everywhere.
