Northeast Florida is a large area with a plethora of lifestyles to choose from. The area is full of history to learn and a ton of areas to have fun at, including a long string of beaches + golf course communities. There are several historic neighborhoods in the center of Jacksonville and to the south in St. Augustine. There are also several rural communities to the west for anyone who prefers large spaces, horses, and privacy. Jacksonville is actually the largest city in the US, land-wise, so as you can imagine, that affords not only a great many things to do from outdoor festivals + concerts to more cultural things such as upscale dining and community theaters.
The climate here is also more mild than parts of Florida south of us, with more days that are cooler and with less humidity.
Northeast Florida has a lot to offer. The difficult thing can be narrowing down what spot is perfect for you.
