Disclosure: The CHP will be displeased to see this published, so please obey the 45 mph speed limit and approach this triple-gulp car ride with caution: Begin in Chatsworth at the Topanga Canyon exit of the 118 freeway with your windows rolled down, heading south, foot off the gas pedal. As you accelerate down the mountain (watch your speed or the motorcycle cops hiding inside the Indian Hills Mobile Home Village will) at about ¼ of a mile, gaze up to the left (east) and take in the magnificent, boulder-embedded Stoney Point Park (gulp 1) — the site of an ancient Indian village — where climbing pros and novices attempt their skills at bouldering, rappelling and downright foolishness. Look right (west) to spot a tiny black hole carved into the Santa Susana Mountains, which is a railroad tunnel built in 1904 (gulp 2). Coast onward (traffic light, hopefully) with the wind blowing in your hair, and pull over. Sit a spell and contemplate the beauty of these historic landmarks you might not have noticed (gulp 3) had you been in a hurry. Stoney Point Park, 11000 Topanga Canyon Blvd., Chatsworth. (818) 883-8531.
