We stopped at Boss's going to and coming from an event, two nights. Very quiet, all sites are level to near level, the owner is super accommodating. Very easy access, plenty of trees but no obstacles! Has all that you need for a very pleasant stay!
We live in Fernandina. We love Fort Clinch but the Ocean side RV sites are not kept up at all. Looks like there are permanent RV sites in places with many vehicles and abandoned RV's. The bath house was yuck and the grounds around it were overgrown. The sites are barren and the pump out station is lacking facilities. The ocean and beach are great and the rest of the park is great.
We were pleasantly pleased with the campground. It has all the facilities and infrastructure as advertised. Having the dump on each site is quite accommodating! The surrounding old growth trees are a wonderful canopy, and all the sites are in the shade! Wi-Fi is adequate but not consistent, and if there is one major complaint the road surface is very dusty and sends a film of white over your RV and vehicles. With amount of traffic going through the campground the dust was quite prevalent.
