What should a first-time traveler see in Denmark beyond the obvious highlights?

Jelling is the founding document of the Danish state, written in stone. The larger of its two runic stones was raised by Harald Bluetooth and records his claim to have united Denmark and Norway and converted the Danes to Christianity; the site also holds two enormous burial mounds and a church between them. It was inscribed in 1994 and sits in central Jutland, far from any coastal resort.

Stevns Klint, inscribed in 2014, is a different kind of monument: a chalk cliff on the east coast of Zealand where the Cretaceous–Paleogene boundary layer is exposed, the thin band of clay laid down by the asteroid impact that ended the age of the dinosaurs. You can put a hand on the boundary. The Viking-Age Ring Fortresses, inscribed in 2023, add a set of precisely circular earthwork forts built to a shared geometry in the late tenth century.

Two more sit at the edges of what a visitor expects. Christiansfeld, inscribed in 2015, is a planned Moravian Church settlement in southern Jutland, laid out on an austere grid with no church tower and separate choir houses for single men and women. The Wadden Sea, inscribed in 2014, is a transnational tidal system along the southwest coast — a landscape that is land twice a day and sea twice a day. Denmark's list also reaches far beyond the country itself: Ilulissat Icefjord was inscribed in 2004, Kujataa in 2017 and Aasivissuit–Nipisat in 2018, all in Greenland.

At Stevns Klint the white chalk face drops straight into the Baltic, and the dark clay seam runs across it as a single thin line you can follow with your eye for as far as the cliff goes.

Denmark is almost flat — its highest natural point, Møllehøj, reaches 561 feet (170.86 m) — and that changes what "scenery" means here. The landscapes on this list are horizontal: a tidal flat, a cliff edge, a geometric forest, a planned grid, circular earthworks seen best from above. None of them photograph the way a mountain does, and several are at their most legible in low, raking light rather than at midday.

• Central Jutland — Jelling's 1994-inscribed mounds and runic stones, with the 2023-inscribed ring fortresses as the companion Viking-Age sites.
• Southwest coast — The 2014-inscribed Wadden Sea on a falling tide, and Christiansfeld's 2015-inscribed Moravian grid inland from it.
• East Zealand — Stevns Klint, inscribed 2014, for the impact boundary in the chalk.

The Wadden Sea is governed by tides rather than opening hours, so a visit timed wrongly shows you water instead of flats. Denmark's wettest month on the national record is November at 3.11 inches (79 mm) and the driest is February at 1.50 inches (38 mm), which means the autumn half of the year is the wrong time for cliff paths and tidal walking. Three of Denmark's twelve properties are in Greenland and cannot be folded into a Danish itinerary at all.
