There are several el-cheapo 1950's motels in High Springs, which is about eight miles North on US Hwy 441. They are, however, inexpensive. It is, however, a peaceful way to spend the night. Surprisingly, there are very few insects and other creatures. If you camp, bring everything you need, including tent, lights, etc.
Children are well catered for.
The site has a treehouse, sandbox, swings and trampoline. Crescent Beach and St Augustine Brach are about 90 miles East. North are the Ichetuckee Springs State Park, famous for its rafting and tubing.
