Arawak Cave NEAR Rhodes Hall

Trying to determine how to take this tour.

Do you have to take the tour through Rhodes Hall plantation or can you just get a taxi and show up at the cave & pick up a guide and proceed with the cave tour.

I understand its $10 /person to enter plus whatever extra after that ,is this accurate?

Trying to fill out the day before heading to half moon beach & Calico Jack's Pirate Shack

Thanks

Cave tour is ok. But the horse riding at Rhodes is better IMO. And snorkeling is great there too! IMO
