At around 7,105 square kilometres, Grisons is the largest canton in Switzerland by area and the only one with three official languages: German, Romansh and Italian. Its high point is the Piz Bernina at 4,048.6 metres; half of the canton's territory lies above 2,100 metres. In 1803 the canton emerged from the free state of the Three Leagues, formed from the fifteenth century onward, which gave themselves a shared constitution with the Bundsbrief of 1524. Near the Lunghin Pass above Maloja, the watersheds of the North Sea, the Mediterranean and the Black Sea meet.

The year as a table to read and to cite: crowd level for every month, plus weather comfort and temperature from the climate normals.

The crowd level is season-relative: 100 is the annual peak of Graubünden itself, not the busiest destination in Europe. The figures say when it is quiet here — not where it is quieter than elsewhere.

Weather comfort 0–100 from the climate normals, profile “mild” – the same profile as the recommendation above, not the selection in the calendar. A “–” means the data for that month is missing.

Slope, lift and elevation figures come from open mapping and are complete to varying degrees. “Not available” means not mapped, not “does not exist”. Opening hours and season are not included. Snow figures are long-term averages for the whole region, not snow depth on the mountain and not a forecast.

At around 7,105 square kilometres, Grisons is the largest canton in Switzerland by area and the only one with three official languages, German, Romansh and Italian; it is likewise the only canton with Romansh, and, alongside Ticino, one of two with Italian as an official language. The canton borders Liechtenstein and the Austrian states of Vorarlberg and Tyrol to the north, South Tyrol to the east, and Lombardy to the south; only the canton of St. Gallen likewise borders three neighbouring states.

Its high point is the Piz Bernina at 4,048.6 metres, its low point the Moesa river on the border with the canton of Ticino at 253 metres; as Switzerland's largest mountain canton, half of its territory lies above 2,100 metres. Most of the canton drains via the Rhine and its headwaters, the Vorderrhein and Hinterrhein; the Engadine is drained by the Inn, the Italian-speaking southern valleys of Mesolcina, Bregaglia and Poschiavo by the Po, and the Val Müstair by the Adige. Near the Lunghin Pass above Maloja, the watersheds of the North Sea, the Mediterranean and the Black Sea meet: from there the Julia flows via the Rhine to the North Sea, the Mera via the Po to the Mediterranean, and the Inn via the Danube to the Black Sea.

The canton counts around 150 valleys, 615 of Switzerland's more than 1,500 lakes, and 937 mountain summits, up to the Piz Bernina. About 9,400 years ago the Flims rockslide occurred, the largest rockslide in the Alps; together with the Tamins rockslide it created the Ruinaulta rockslide landscape. Around 300 bird species are recorded in Grisons; the Avers valley has its own marmot nature trail.

The canton emerged in 1803 from the free state of the Three Leagues, formed from the fifteenth century onward: the League of God's House of 1367, the Grey or Upper League of 1395, and the League of the Ten Jurisdictions of 1436, which united from 1450 and gave themselves a shared constitution with the Bundsbrief of 1524. Chur, the canton's capital since 1803, is held to be the oldest continuously settled town in Switzerland; as a bishop's seat it is first recorded around the year 452. From 1900 to 1925 driving automobiles on Grisons roads was largely banned; only on 21 June 1925 did the population narrowly vote to admit cars seating up to eight.

Grisons is held to be the canton with the greatest density of castles. The Benedictine convent of St. John in Müstair, the village of Soglio and the church of Zillis are cultural properties of world rank; the church of St. Martin in Zillis carries a painted wooden ceiling with biblical scenes. The Salginatobel Bridge near Schiers has been, since 1991, the only Swiss structure honoured by the ASCE as a world monument. The cantonal coat of arms is assembled from the arms of the Three Leagues.

The Rhaetian Railway runs on metre gauge through most of the main valleys; it operates the Bernina Express and, jointly with the Matterhorn Gotthard Bahn, the Glacier Express. The cantonal road network comprises 597 kilometres of main roads and 826 kilometres of connecting roads, plus 166 kilometres of national roads that passed into the federal government's sole responsibility in 2008. The most important passes between north and south today are the San Bernardino, between the Rheinwald and the Mesolcina, and the Julier Pass into the Engadine, already crossed by carts in Roman times. Since 1 January 2016 the canton has been organised into eleven regions; as of 1 January 2025 it comprised 100 municipalities. Grisons cuisine includes air-dried Bündnerfleisch, Salsiz, Capuns, Pizokel, Maluns and the Bündner nut tart; the Bündner Herrschaft is the canton's largest wine-growing area.
