The family that designed this property wasn’t looking for something typical. The Santa Ysabel, Calif., estate sits on 720 acres about 30 minutes from San Diego. David Batchelder of Relational Investors purchased the land in 2000.

In 2006, Batchelder added the 3,500-square foot home and several adventurous amenities to the expansive Southern California ranch. The property owner wanted to create fun, outdoor alternatives to smartphones and video games for his grandchildren.

He definitely achieved that goal. The estate features a go-kart track with several motorized engines for plenty of high-speed fun. The half-mile long track twists and turns like any professional course.

Friends and family can also opt for a dip in the massive 650,000-gallon pool. The estate also features a paintball park, putting green, stocked fishing ponds, riding trails, and areas for skeet shooting and archery.

A small head of cattle graze the grounds to keep the grass in tip-top shape. Better yet, they’re included in the sale price along with tractors, golf carts, go-karts, and a caretaker.

The house itself is modern and homey with four bedrooms, wood-beam interiors, and a large kitchen designed for entertaining.

Now that Batchelder’s grandkids are grown up, he and his wife have relocated to a family farm in Pennsylvania. The adventurous property is perfect for a family and also features two guesthouses and two caretaker homes. It’s currently listed at $17.5 million.
