The Windautal is a southern side valley of the Tyrolean Brixental in the Kitzbühel Alps in Austria with a length of about 16 km.
The Windautal is a popular recreation area and a particularly good for ski tours, hiking, mountain biking and cycling.
The route through the valley along the lower reaches of the Windauer Ache is part of the "Kaiser Circuit (Kaiser-Runde), a long distance circular cycleway that starts and ends in Kufstein.
The Salzburg-Tyrol Railway runs along the slopes and through several tunnels of the lower (northern) Windautal, where, in the middle of a curve, a bridge spans the valley.
Above the tree line the open slopes are used as grazing pasture for sheep, goats, cows and horses.
