Central Alaska is a region in Alaska.
The greater Fairbanks area is a strange place. Fairbanks proper is like a lot of towns in the lower 48. There's a Wal-Mart, a Home Depot and a McDonald's. Don't let this fool you. There are plenty of Alaskan originals here.
Chena Hot Springs, located about an hour's drive from Fairbanks, is one of the best attractions in the interior of Alaska. The hotel is run almost entirely on geothermal energy, and the greenhouses grow food for the restaurant. The hot springs themselves are best enjoyed in the wintertime, when the icy air contrasts nicely with the hot water. Because of the lack of light pollution, it's also a wonderful area in which to view the Northern Lights.
In Fairbanks itself, there is the University. A dynamic research University, there are ongoing studies about everything from the best ways to engineer buildings for the harsh Alaskan landscape to climate change. There's a museum featuring Alaska Native arts, a botanical garden, and a large animal research station with plenty of muskox and reindeer to view. The University of Alaska system as a whole is making a push for sustainability, and this can be easily seen in the many greenhouses dotted around the campus. Many of the vegetables served in the dining halls and cafes are grown right on campus.
Pioneer Park (formerly Alaskaland) is also located in Fairbanks. It features actual pioneer homes that were moved from the downtown area into a central location that people can wander through to learn more about the pioneering history of Alaska.
