Good for you for taking the time to ask. You'll find this board to be pretty responsive to people so if you have other questions, throw them out there. Main Beach in Laguna is not a difficult beach for swimming. It is a shallow breaking beach with little or no surfing. There are numerous other coves along the shore line that that are swimable depending upon your ability level. Some have surfing around them, some don't.
Some beaches span in front of our hotels and resorts, however, there is no private beach in Laguna Beach. No matter what your mood, Laguna Beach has a beach that perfectly suits you. If it's people watching and easy access to restrooms and restaurants you seek, try Main Beach or if you're looking to have a bonfire head over to Aliso Creek Beach (the county beach).
