Agoura Hills is a small town, so the easiest way to get around is by car. If you are flying into Los Angeles, you can rent a car at the airport and drive the 35 miles to Agoura Hills. Expect to pay around $50 for the day's car rental, and budget for a gas of around $20.
If you have more time, we recommend checking out more of Malibu Creek State Park or visiting the nearby beaches. If you are short on time, consider skipping the M*A*S*H set and heading straight to Peter Strauss Ranch. Don't forget to bring sunscreen, comfortable shoes, and a camera to capture your adventure!
