We parked in the Larrabee day parking area, it was a nice short day jaunt. No snow or bugs. We went around 2 PM, and the parking lot had about ten or so cars. We saw about 18-20 people while we were out there, and unfortunately none of those individuals bothered to put masks on. My guy and I were the only ones. Typically wasn't too much of an issue, most areas were large enough you could get 6+ feet away from people without wandering off the trail.
Unfortunately, we were unaware the beach was closed to public access. We didn't see any posted signs while we were out there. I do understand the concern, there was two groups of people walking on the tracks when we crossed over them. But if you use common sense and pay attention to your surroundings, you should be just fine. There was also enough trash to easily fill a household garbage bag. Disposable masks, wrappers, coffee cups.
Beautiful views, the beach is absolutely amazing. You do have to climb down to access the beach, but I wouldn't consider it undoable for someone with no experience.
