The house actually belongs to Girls Gone Wild founder Joe Francis, who is a close friend of the Kardashian/Jenner crew. It has pretty much every amenity anyone could ever want, including a masseuse, personal training in the private gym, a sea lion encounter in the private pool, entertainment of all kinds - including a Mariachi band - and pretty much every water sport you could ever want to try.
Here's a look at the backyard, which you might recognize from your favorite Kardashian's vacay pics:
Here's one of Kourtney Kardashian hanging with Joe (the homeowner) during one of her visits:
When Kendall and Kylie visited this week for Ky's 18th birthday bash, it wasn't their first time there, either. The Casa Aramara Instagram shared this throwback of the Jenner sisters enjoying a BBQ at the retreat.
A stay at Casa Aramara doesn't come cheap, though. The cheapest rental rate - during the "low season" - is $12,000 a night and going all the way up to $35,000 a night for New Year's...although it's already booked, so if you had $35,000 burning a hole in your pocket and wanted to spend it there, you'll have to wait until next year!
