Doheny is a wonderful beach, especially for surfing, camping, grilling, or just hanging out for the day.
To begin, the parking is easy and close to the beach<100 ft. Additionally, the parking lot is the same altitude as the beach. Which after a long day in the sun and ocean makes the trek back to your vehicle or public transit quite easy.
The beach itself is pretty solid, but, quite riddled with natural sediment. Think bigger rocks, thicker sand, larger pieces of drift wood. You can get away with using a towel to lay down, but, I would strongly suggest bringing a beach mat (like a banig.)
Getting to the ocean is easy, I certainly suggest bringing water shoes though. The ocean itself has quite large rocks for the first 150-200 ft. that can really wreak havoc on your toes/feet.
Once you are out there, though, it is great-serene and relaxing. It can get a little overcrowded at times, but, the ocean is big enough for everyone.
As for the facilities, there are easily accessible bathrooms and outdoor showers, grills next to the picnic tables, and a little food area that has ice cream, water, snacks, and beer. New good options are forthcoming.
Overall, a wonderful time with great access and amenities.
