This year marks the tricentennial of a turning point in North American colonial history. Three centuries ago, British soldiers established their first fort on land that was to become the colony of Georgia. Called Fort King George, it protected a low bluff on the mighty Altamaha River from French and Spanish explorers. Today, the site is open for tours where visitors can explore reconstructed buildings including barracks, a guard house, tavern, moat and palisades. Guests are welcome to climb ladders inside the blockhouse, lay on soldiers’ bunks, peek out musket holes and even ring the dinner bell. Join historians throughout the year during their speaker series.

Ready for an all-ages, modern treasure hunt? Georgia’s State Parks just launched a new “GeoTour” with caches at 45 parks, divided into regions. Your goal?

Showcasing sparkling Lake Seminole, this 604-acre park is a haven for boating, fishing and birding. Cottages and some campsites sit near the water’s edge, perfect for enjoying morning coffee with a view. During summer, cool off at the lakeside beach, and throughout the year,  scout for wildlife such as bald eagles, deer, alligators and raccoon.

Take time to celebrate Spring’s arrival by exploring someplace new. Make a cozy cabin your base camp so you get down and dirty with fishing, hiking or kayaking somewhere you’ve never been before. Scout for fiddler crabs at low tide at Crooked River, or listen for owls welcoming the night at Reed Bingham. Climb ancient platforms at Kolomoki Mounds, or walk the footsteps of colonial soldiers at Fort Morris. State park cabins, campsites and yurts offer a range of accommodations for all budgets, making it convenient to stay several days. Check out even more ideas for outdoor fun.
