This spot requires a permit, has male and female bathrooms and a few outdoor showers that are "cold". These are shocking at first, but quickly you become accustomed and it feels nice due to it being "room temp". There were two main issues with the stay, both of which happened on varying nights of the week (Monday and Friday). The roosters are plentiful and begin around 3 am here, with the toads coming out as the sun goes down. The roosters provide a great alarm clock if you want to get up in the middle of the night. The other aspect was that it seemed more like a "locals" campsite with several hanging flags or graffiti mentioning the hatred for the contiguous 48 states and howlies. Did not experience anything that would make it unsafe, but on Friday evening, the locals were partying loud until 2-3 am, so if that's your thing, you will love it, we had an early morning itinerary, so we did not too much. The beach is good with ample space.
This campground features both male / female bathrooms and has two outdoor showers available. The showers are "cold", which in Hawaii, means room temperature, so after the initial shock, it actually becomes quite comfortable. I do not recall if there were picnic tables, but at the most maybe one or two. It does require a permit, but those are easy and cheap (~$3). I elected to post up under the tree section, which provided a good cover, flat ground and actually had a downed tree that I used to set up backpacking stove for coffee in the morning. There were a few small fires on the beach throughout the stay, but I don't believe it is technically legal to do so. Overall, my favorite place to stay in Kauai with the given options due to the recent storms and North Shore closures.
