Depending on which direction you hike (from La Jolla Shores, north to Torrey Pines, or from Torrey Pines, south to La Jolla Shores), this page has three maps available in .jpg format for download and printing to carry with you on your hike. The low resolution .jpg files can be saved to your desktop, then printed out.
The beach is wider at Torrey Pines/Blacks Beach, and narrower near the southern bluffs and Scripps Pier at La Jolla Shores. Keep in mind the high and low tide times, and plan accordingly. Tide Tables for San Diego County
The best approach for a one-way hike is to use a minimum of 2 vehicles. Stage a vehicle near the end of the hike, so you can drive back to the beginning point and pick up the other vehicle. See bottom map below for suggested driving route.
