questions about deep creek

I've been to Deep Creek twice, I usually travel down Bowen Ranch Road from Roundup Way, pay Mike at the house, park my car in the main lot, and hike down the trail into the canyon where there are 3 main hot pools (you have to wade accross the creek to get to them). Are there any other pools? And where is this garden I've heard about? Someone also told me about a waterfall with a small cave behind it, where the Manson family used to stay. Are there any waterfalls or caves? And what other ways are there to Deep Creek besides from Bowen Ranch? Am I missing out on anything besides the 3 pools south of Bowen Ranch?
