Here's another cache that's aimed at family caching. Older kids can play too, but it's intended for the younger set.
Seabranch is a large natural area, on Hwy A1A, just south of of Port Salerno. There are many trails and areas to explore; it's well known for it's "sugar sand" paths, so be prepared for a slightly difficult hike. Bring water and dress for some mild bushwacking.
The cache is just off the South Loop trail; you'll find the trailhead about 500' east of the parking lot.
When placed this cache contained "creepy stuff" and a log. Kids don't have to trade something to take something. Please replace the cache as you find it and ensure that it is closed properly.
