Good gravel riding. Some more technical terrain in the middle with smoother stuff at the west and east ends. For a less rowdy option, start on south main trail and switch to north main trail between sycamore and wagon wheel crossings.

Sunset Cliffs Boulevard in San Diego is a fantastic spot for road cycling, offering a scenic, mostly flat route with breathtaking coastal views. Starting near the Ocean Beach Pier, you can ride south along Ocean Front Street before joining Sunset Cliffs Boulevard at Point Loma Avenue. The road winds along the coast, ending at Ladera Street, with a mix of paved sections and gravel pullouts that provide ample opportunities to stop and admire the stunning ocean vistas and dramatic cliffs. As you ride, you get expansive views of the Pacific Ocean, often with surfers riding the waves below or sea birds flying over the water. While there isn't a consistent dedicated bike path due to erosion, the road is still fairly biker friendly.

The Ho Chi Minh beach access should not be your first choice for getting to Blacks Beach. The path is unique and spectacular, but it is not without its challenges. There is an official access not far from this access that is much safer. You really shouldn't go too far there, especially with children or people with less sure footing. I even turned around at one point because I wasn't wearing the best footwear and looked for an alternative route. I was shocked at the number of tour groups I encountered.
