Catalina Island is perhaps one of the most unusual places to visit in California, as well as one of the most historically significant US islands. A strange combination of island paradise, baseball history, and bison grazing lands, Catalina Island has something to attract all audiences. The inhabited part of the island, Avalon, is relatively compact. This, paired with the exceptionally high gas prices that come from island living, means that most people use golf carts to explore the island.

Beyond the borders of Catalina’s million-dollar mansions are the undeveloped acres of shrubbery. Numerous native species can be spotted by exploring this region, including the Catalina fox, a smaller cousin to the mainland red fox. There is, however, one truly over-sized resident in Catalina. A herd of bison, left behind after an old western movie was filmed on the island, calls Catalina home. Now protected by the National Park Service, tours of the bison herds are one of the best things to do on Catalina Island.

Despite the lack of motorized vehicles, there is still plenty to enjoy on Isle Royale. A popular destination for backpacking, boating, fishing, and hiking, Isle Royale is a bit of a step back in time.
