This $11 million listing in an exclusive Orange County community has an insane backyard

Pirate shipCourtesy of Berkshire HathawayLagoons, caves, waterslides, a pirate ship — this is the backyard of your childhood dreams.

Recently listed for $US10.99 million, this 9.5-acre estate in California’s exclusive Coto De Caza community features a backyard wonderland complete with a grotto, lagoon, and pirate ship.

Coto De Caza is a gated community best known as the original setting for Bravo TV’s “The Real Housewives of Orange County.” John Frankhouse, a former mortgage banker with a passion for real estate, owned the home until his recent passing.

In 2001, Lakers player Kobe Bryant and his wife reportedly made and later rescinded an offer on the home at its previous asking price, $US13.5 million. Lyn Chadwick and John McMonigle of Berkshire Hathaway HomeServices hold the listing.

With nine bedrooms and two bathrooms, the home is part of the exclusive Los Ranchos Estates neighbourhood.

A spectacular entryway leads to the main house living area.

The home is equipped with an intercom system and surround sound throughout.

The galley kitchen includes a warming drawer and an enormous center island.

Off the kitchen, the den is appointed with a wet bar, built-in wood cabinetry, and stained glass paneling.

Relief moulding, sizable columns, and French doors add a sense of grandeur in the formal dining room.

The master bedroom has a private sitting area, terrace, and one of the home's seven fireplaces.

The master bath is full of decorative accents, from the extensive marble to the etched cabinetry and stained glass windows.

The home office is complete with incredible hand-rubbed wood paneling.

And there's more hand-rubbed wood in the billiard room, which has balcony access.

The state-of-the-art home theatre actually looks like a movie theatre.

Outside, a lagoon is fronted by a pavilion and lookout tower.

A barbecue area on the side of the house boasts plenty of space for entertaining.

An aerial shot of the property's backyard speaks to its lush surroundings and theme park environment. The estate is also listed as a 'horse property.'

The pool is flanked by a rock formation that doubles as a water slide. There's also a wade-in dock and waterfall terrace.

A replica three-story pirate ship is perhaps the home's wildest feature.

To the left of the main house is the guesthouse -- a two bedroom residence with a full bathroom and caretaker room that sits above an additional four-car garage.

A stunning nighttime aerial shot of the estate shows its prime hilltop location.
