We just got back from 4 nights at this campground and enjoyed ourselves thoroughly. We were disapointed in our site, as it was on a corner, with a really odd shape, while there were TONS of empty spaces the entire time, but it wasn't that big of a deal. It was a bit of a drag not having a sewer hookup, as we only have a 30 gallon grey water tank, but not a deal breaker. They have one dump station and on one day, we saw about 20 vehicles lined up to use it, so plan accordingly.
The first day was raining, so we just set up and once the sun was out, we went fishing. The next day, we took our kayaks and launched right at the office and took a right out of the canal, which lead us to Billy's Lake and then to Billy's Island. We saw lots of turtles, birds and a ton of really big gators, but none bothered us. Once you are at Billy's Island (2 mile paddle from the office, which took us an hour each way), you can get out and take a walk around the island on their designated trail. There's not a lot to look at, as it used to be a settlement where Native Americans and then AWOL soldiers hid to avoid detection. The next day, we decided to give our muscles a break and rented a Skiff, which was $60 for two hours and I think $80 for 4 and that was awesome. They provide Life Vests if you don't have them, but you can take your fishing equipment, cooler or what have you and go explore all the tributaries. We took a left out of the canal and went until the river ended and then went back up and into the small waterways to Minnie's Lake, which was our absolute favorite. It was so beautiful and serene. There were quite a few boats, so kayaking back there could be challenging, but they are supposed to go slow and most did. You can also take a guided tour and we saw several go out with just one couple per boat, so that's a good option for those who like a calmer experience.
We feel like we saw everything the park offered and if you've never been to the Okefenokee Swamp, I highly recommend it. It was really great.
