Earlier parts in the series: Africa, US & Canada, Oceania, Latin America & Caribbean.
Each answer is a place, landmark or attraction in Eurasia, one per country. The answers traverse all countries by crossing land or maritime borders. (In some cases, it's necessary to pass through a previous country in order to get to the next one.) Each clue is missing a country name or demonym from another clue (not the answer to that clue, just the name of the country).
Notes:
- Some long names have been shortened. For example, if the full place name is "Xyz Royal National Park", the answer will be just "Xyz" (often with "royal national park" or similar as the definition).
- While many of the answers are obscure, all of them are notable enough to have a separate article on the English Wikipedia.
- The list of countries includes all Eurasian members of the United Nations plus Kosovo, Palestine, Taiwan and Vatican City.
- The country names mostly follow Wikipedia's naming conventions: Myanmar instead of Burma, East Timor instead of Timor-Leste, etc. However, Ireland is just Ireland here.
