The area of Vaz/Obervaz extends from Parpan in the north to Alvaschein and Lantsch/Lenz in the south, and from the mountain chain of the Parpaner Rothorn in the east to the expansive alpine meadows of Piz Scalotta, Dani and Stätzerhorn. On the southern slope of Mount Crap la Pala, the land rises steeply up the sharply cut sides of the ravine of the Albula. Accordingly, the elevation differences within the municipality are large: from the lowest point of about 700 meters elevation in the Schin gorge, the highest point, on Mount Parapaner Rothorn, is 2865 meters in elevation.
The Vaz/Obervaz area encompasses the northern boundary with Parpan, extending southward to Alvaschein and Lantsch/Lenz, and eastward to the mountainous terrain of the Parpaner Rothorn. The land rises dramatically on the southern slope of Mount Crap la Pala, forming a steep ravine in the Albula valley. As a result, the municipality experiences considerable elevation differences: from the lowest point near the Schin gorge (around 700 meters), the highest peak, Mount Parapaner Rothorn, reaches an elevation of 2865 meters.
