How is the Nausea Index scored?

Each entry inherits the risk rating already published in its Dizzout guide: gentle 25, manageable 50, rough 75, notorious 92. The guides draw on geography, operator information and rider reports. Equal ratings tie because the index does not pretend to more precision than the guides carry.

What is the most nauseating journey on Earth?

The top tier holds 13 entries rated notorious, led alphabetically by the roughest sea crossings and the most intense spinning rides. See the full ranked list on this page.

Can you prepare for a notorious trip?

Yes. Every entry links to a guide with seat or cabin advice and prevention steps, and the free trip planner turns a date into a day by day checklist.

The Nausea Index 2026

The rockiest journeys on Earth, ranked

84 sea crossings, theme park rides, road trips and cars in one list, scored from the risk assessments in our guides. Find your trip. Then prepare for it.

The Nausea Index ranks 84 journeys by how often they make people motion sick: 13 sit in the notorious top tier. Scores map the four risk bands used across our guides (gentle 25, manageable 50, rough 75, notorious 92), so a score summarizes a full guide, not a lab test.

84 of 84 entries shown. Equal ratings tie on purpose: the underlying guides rate in four bands, and this index does not pretend to more precision than they carry.

How the index is scored

Every entry already has a detailed Dizzout guide with a risk rating built from geography, operator information and rider reports. The index inherits that rating directly. Nothing is re-measured and nothing is invented: equal ratings tie, and the way to break a tie is to read the two guides.
