Kellerjoch is one of the most popular viewpoint mountains in Tyrol, known as the local house mountain of Schwaz in the Inn Valley. Its main summit, Kreuzjoch (2344 m), is crowned with a small mountain chapel and offers sweeping views across the Tuxer Alps and the Inn Valley below.

Kellerjoch forms the northernmost outpost of the cross-shaped eastern massif of the Tuxer Alps, which also includes Rastkogel, Pangert and Gilfert. The ridge stretches from the rocky Metzenjoch (2313 m) across the main summit Kreuzjoch to Kuhmesser (2264 m). In summer the landscape is a mix of green alpine pastures and rugged rock, with far-reaching views over surrounding peaks, while winter transforms it into a proper alpine setting with snow-covered slopes. It's a rewarding destination year-round for hikers wanting big views without an overly technical climb.

• Grafenast (1330 m) — chairlift (three sections, only the last one runs in summer) up to Hecherhaus (1887 m), followed by a hiking trail to the summit
• Schwaz — hiking trails passing the Alte Kellerjochhütte, moderate difficulty, several hours of walking

• The summit chapel on Kreuzjoch is reached from the (new) Kellerjochhütte (2237 m) via a path partly secured with steel cable
• Berggasthof Hecherhaus makes a good stop along the way

On 21 November 1990, a Beechcraft King Air 200 flying from Trieste to Innsbruck crashed into Kellerjoch, killing German steel industrialist Willy Korf and two crew members.
