Take a short seaplane ride, or take the ferry from St. Croix to St. Thomas. If you don't like to travel by water, you can hop flights from many commuter airlines offering service to these and other neighboring islands in the Caribbean.

The most reliable and efficient way to travel between St. Thomas and St. Croix in the U.S. Virgin Islands is by Inter-Island Commuter Flight. Airlines like Silver Airways and Cape Air operate "puddle jumper" flights that take only about 20 to 25 minutes. This is the preferred method for locals and tourists alike because it avoids the rough seas often found in the "Anegada Passage" between the two islands. For those who prefer a more adventurous or budget-friendly option, a fast ferry service (such as the QE IV Ferry) occasionally operates between the Charlotte Amalie waterfront in St. Thomas and Christiansted in St. Croix. The ferry ride takes about 90 minutes to 2 hours, but it is notorious for being "bumpy," and services can be frequently canceled due to high swell or mechanical issues. Seaplane services, like those operated by Seaborne Airlines, offer a unique "downtown-to-downtown" experience, taking off from the harbor in St. Thomas and landing in the harbor of St. Croix, which is incredibly convenient for avoiding airport security lines and enjoying stunning aerial views. For most travelers, the convenience and speed of a 20-minute flight far outweigh the potential seasickness associated with the ferry.
