Liechtenstein
One summit, three countries: Austria, Switzerland and Liechtenstein meet under your boots at 2,570 metres.
The Naafkopf is the mountain where three borders run out of land: Liechtenstein, Austria and Switzerland all end at its 2,570-metre summit above the Naaftal. Reach it at sunrise from the Pfälzerhütte and the light arrives over three countries at once.
The official Liechtenstein tour is a serious 19-kilometre mountain day: eight and a half walking hours, 1,258 metres of ascent and nearly as much back down, with ibex sometimes watching from the rubble slopes. Most walkers break it at the Pfälzerhütte on the Bettlerjoch, from which the summit push is roughly two hours out and back, close enough to make a dawn start realistic. Difficulty depends on the chosen line: the north-eastern approaches are graded T2 over rubble, while the full Sareis-to-Älplibahn traverse runs at T3+ against the mountain's steep south-western rock faces. It is a genuine alpine objective, and the forecast and current route conditions dictate the day's terms.
Solo
For an experienced solo hiker the tripoint is a rare, self-contained prize; the long approach plus the choice between T2 and T3+ lines are real mountain decisions to make honestly.
Couple
Book the hut, climb to the border stone country by country in the morning, and share a summit that neither of you can stand on without being in three places at once.
Friends
The group version writes itself: dormitory bunks at the Pfälzerhütte, an alpine start, and one photograph at 2,570 metres that needs three captions.
The Pfälzerhütte below the summit feeds its overnight guests a three-course vegetarian dinner before the morning's climb; payment is cash only.
Above the hut nothing is sold or served, so water and pocket food for the two-hour summit round trip go up in your pack.
