The main asset of Cinnamon Bay Campground is that it is located directly on a strikingly beautiful beach. Snorkle gear, as well as other water sports equipment, can be rented at a small beach-front shed at reasonable prices. Right off the beach is a rich coral reef: I saw a nurse shark, a troupe of fluttering brown and white squid, purple fan coral, parrot fish and more. It was satisfying not to have to pay a tour operator to bring me to a reef, especially because I was on a budget.
Another nice thing about the campground was open-air showers and the on-site convenience store. They were cold, but it was very hot and this was definitely not an issue.
The campground does not have good lighting at night so bring a strong flashlight. I rented a tent cabin. It was not as clean as I would have liked for the rate I was paying ($40 a night). The flaps did not have a zipper, only ties, and so did not close well. A few mornings I woke up with mongoose, which are rampant on the island, inside my tent. These were minor inconveniences, however.
Even though linens are included in the price of the tent cabin, bring your own sleeping bag. It is not cold at night, but the mattresses are standard pin-striped plastic and not very comfortable.
I think this campground would be good for travelers who are willing to give up a few luxuries for a great location. Overall, I found I didn't miss them too much. The campground experience added to the quirky nature of the trip.
I would not, however, return there again alone. The campground, and in fact the entire island is more for couples and families. Though I am usually content to travel solo, I was lonely and bored at night.
