Big-name parks come with big crowds, and crowds breed letdowns. Outdoor brand Kühl put that idea to the test, applying the travel phenomenon known as "Paris Syndrome" — the crushing disappointment some visitors feel in the French capital — to America's national parks. Using around 96,000 Google and Tripadvisor reviews, they measured which parks drew the highest share of negative feedback. The result: a tie at the top between two parks most travellers never consider.

Virgin Islands National Park and Minnesota's Voyageurs National Park each logged just 2.2% disappointed reviews, making them statistically the least disappointing parks in the system. They could hardly be more different on the surface — one is a Caribbean beach idyll, the other a remote boreal waterway network — yet both offer the kind of experience the marquee parks increasingly struggle to deliver.

Virgin Islands National Park covers roughly 7,000 acres, about 60% of St. John, the smallest of the three US Virgin Islands. Coral reefs, mangrove forests and green mountains give it serious natural range, and Trunk Bay Beach regularly ranks among the world's best. There's history too: the Annaberg Sugar Plantation tells the story of slavery and survival on the islands, while Taino petroglyphs dating back a thousand years survive in the park. Snorkelling, boating, fishing and hiking round out the options, and reviewers call it everything from "pure paradise" to one of their favourite national parks.

Voyageurs, 10 miles east of International Falls in northern Minnesota, spans 218,000 acres of lakes, southern boreal and northern hardwood forest. Named for the French fur traders who passed through in the 17th and 18th centuries, it sits on glacier-carved terrain with some of the oldest rocks on Earth, dramatic Grassy Bay Cliffs and top-notch views over Rainy Lake. Being that far north, it can also deliver strong northern lights displays.

The catch — and the appeal — is access. Large parts of Voyageurs are reachable only by boat, so visitors tend to be paddlers willing to put in the effort rather than drive-up crowds. That self-selecting visitor base is probably part of why disappointment is so rare. The same logic applies to both parks: no massive infrastructure, no bottleneck viewpoints, just visitors who chose deliberately and got what they came for.

For travellers weighing a 2026 park trip, the takeaway is simple. If you want snorkelling and white sand without Grand Canyon-style congestion, St. John delivers. If you want solitude, water and the chance of aurora, Voyageurs is worth the trek to the Canadian border. Either way, the data suggests you're about as likely to be wowed as you can be.
