Luž (793 m a.s.l.) is the highest peak of the Lusatian Mountains — a bold phonolite dome sitting right on the Czech-German border. It offers one of the most sweeping panoramas in the whole region, and you can literally step from the Czech Republic into Saxony at the very top.

Despite its modest elevation, Luž has a surprisingly wild feel. The summit zone is protected as a nature reserve on both sides of the border, cloaked in old-growth forest. Autumn transforms the beeches and maples into a blaze of gold and crimson, while winter brings snow-dusted vistas that stretch seemingly endlessly. On a clear day the view spans from the Ore Mountains and Děčín Snowdon across the Bohemian Highlands, the rocky towers of Trosky, all the way to Ještěd and the Krkonoše peaks. To the north lie the towns and hills of Upper Lusatia in Germany.

• Horní Světlá (parking at Chata Pod Luží, approx. 1 km from the summit) — red-marked trail, approx. 30–40 min, easy
• From the German side — Waltersdorf (Saxony), blue-marked trail from the north, known as the Lužická cesta route

• The summit straddles the Czech-German state border — Czech and German regulations apply on their respective sides
• A freely accessible viewing tower with a relay mast stands on the German side of the summit, opened in August 2020
• The ruins of the old mountain inn (burned down in 1946) on the Czech side have been adapted into a viewing terrace
• A summit visitors' book records around 10,000 visitors per year, mostly from Germany
• Food and accommodation available at Chata Pod Luží and Lužická bouda in Horní Světlá–Myslivny, about 1 km southeast of the summit

The old inn that once stood here was famously split by the border — it had two separate post boxes, one Austrian and one German, and guests had to make sure they dropped their postcards into the right one!
