One way to escape the crowds during a summer vacation is to head somewhere not connected to the rest of the country by road. This means islands with no bridges or parts of the country are cut off by natural features that make road access impossible.

Visiting these pristine locations may take a little more time and effort, but in the end, it is worth it as you will be able to enjoy a place without the coming and going of tourists driving through for a quick stop.

All of these locations are accessible by ferry, and some have small airports that are capable of handling private or limited commercial air traffic.

Seldovia, Alaska

Located just across Katchemak Bay from Homer, Alaska, Seldovia is a small town of 250 hearty souls who are willing to enjoy a quiet, secluded life in exchange for having to reach the rest of civilization by taking a ferry or small plane. This picturesque part of Alaska is nestled up against the rugged Katchemak Bay State Park, where the bears and glaciers far outnumber the humans living here.

Did you know that the massive 1964 earthquake that shook this region of Alaska caused the town of Seldovia to sink 4 feet? After the quake, the town had to be rebuilt on higher ground, and many of the buildings ended up in the water!

Seldovia can be reached from Homer by ferry, private water taxis, or air service (be prepared to hop on a very small plane.)
