To get there from Ratchaburi go to the central part of downtown. Look for the main post office. Near the entrance you'll see a makeshift minibus depot. Let them know you'd like to go to "Tham Khao Bin" going towards Amphoe Chom Bueng. It's a 20 minute ride. Having your phone will help the driver to drop you off along the busy highway. Cars drive dangerously so be careful. It's a 2km walk toward the park entrance. If you're lucky, someone will be kind to save you a short trek.
Don't mind the monkeys. They will not bother you. Upon arrival you'll see a playground to the right and friendly shops selling coffee, trinkets.
To enter walk around the fish pond, stay to the right. The park fee is nominal. Be prepared, the cave is dark and humid. You may get alittle muddy and it wouldn't hurt to have a flashlight or headlamp to navigate. Guided tours were done in Thai. You're welcomed to join or take your time to see the stalactite formations.
Exit and refresh before heading back. Cross the busy highway and wait for a minibus going back downtown. The minibus may flash their lights to see if you want a ride. A downward signal, a polite "yeah" will get them to stop. You will be dropped off inside the post office parking lot.
