Island travel has a specific quality that mainland beach destinations can't replicate: the sense of actual remove from ordinary life, the contained geography that makes the whole island feel knowable, and the particular intensity of beauty when water surrounds you in every direction. Here are the best US island destinations for summer 2026.
New England Islands
Nantucket, MA
The character: The most preserved and architecturally cohesive New England island. Grey-shingled cottages, cobblestone streets, extraordinary beaches, serious food scene, and a summer community that has been coming for generations.
Best beaches: Surfside (accessible, great waves), Great Point (remote, accessible only by 4WD or long walk, extraordinary), Miacomet (local's beach, less crowded).
The honest note: Very expensive. The island has become one of the most expensive summer destinations in the country. Worth it if the budget is there; there are better-value alternatives if it isn't.
Pack: Premium beach towel and a quality tote — the Nantucket beach aesthetic rewards the elevated beach kit. Browse our towel collection and tote collection.
Martha's Vineyard, MA
The character: More diverse and town-varied than Nantucket — each town (Edgartown, Oak Bluffs, Vineyard Haven, Aquinnah) has a distinct character. Slightly more accessible price point than Nantucket. The Gay Head Cliffs at Aquinnah are among the most striking geological features on the East Coast.
Best beaches: South Beach (longest stretch, good waves), Lucy Vincent Beach (permit required, worth the effort, dramatic cliffs), Menemsha Beach (sunset-facing, legendary views).
The honest note: Getting here requires a ferry that fills quickly in summer. Book the ferry the same time as the accommodation.
Southern Islands
Key West, FL
The character: The southernmost point in the continental US, with a specific history of artists, writers, pirates, and characters that gives the island a culture distinct from generic Florida beach tourism. Duval Street is tourist-heavy; the side streets reward walking.
Best activities: Snorkeling at the Dry Tortugas (a day trip or overnight by ferry), cycling the island end to end, Mallory Square for the nightly sunset celebration.
The honest note: The water around Key West is murky — not the turquoise clear water that photos suggest. For that, you need to go offshore to the Dry Tortugas or the reef.
US Virgin Islands
The character: American territory with Caribbean environment — no passport required, USD, and US legal system, combined with genuine Caribbean marine environment and culture. St. John in particular is 60% national park, with protected beaches and extraordinary snorkeling.
Best beaches: Trunk Bay on St. John (snorkeling trail, one of the world's most photogenic beaches), Cinnamon Bay, Magens Bay on St. Thomas.
Pack: A quality beach towel and reef-safe sunscreen — see our sunscreen guide for what that actually means in the USVI context where chemical sunscreen restrictions apply.
Pacific Islands
Maui, Hawaii
The character: The best combination of beach quality, landscape variety, and visitor infrastructure in Hawaii. Road to Hana is the definitive Hawaiian scenic drive. Haleakalā National Park at sunrise is transformative. The beach variety is extraordinary — from black sand to red sand to perfect white crescent beaches.
Best beaches: Kaanapali (accessible, consistent), Hamoa Beach (the most beautiful beach in the state according to many), Red Sand Beach (requires a short hike, completely worth it).
The honest note: Post-wildfires, parts of Maui are still rebuilding. Check current advisories before booking and consider staying on the east side (Hana area) or south side (Kihei/Wailea) which were less affected.
