Gobba di Rollin, Mountain summit at Italy-Switzerland border, Valais.

Gobba di Rollin is a mountain summit on the Italy-Switzerland border in the Valais region, rising to 3,899 meters. The peak features a broad glacial surface and a notably flat summit plateau that sets it apart from nearby alpine peaks.

The summit's flat ice cap has allowed vehicles to reach it from the Theodul Pass, a European record for altitude attained by 4x4. The mountain is the highest point of the Matterhorn Glacier Paradise ski area, linked by lifts to the Klein Matterhorn and Testa Grigia. Its Italian and French names both refer to a back or hump.

The summit is the highest point of the Matterhorn Glacier Paradise ski area, served by Europe's highest ski lift. It is linked by lifts to the Klein Matterhorn and Testa Grigia, and summer skiing takes place on the Theodul Glacier. The Italian name refers to the French "dos" (back), while the variant "bosse" (hump) is also attested.

Visitors can reach the area from the Klein Matterhorn station at 3,820 meters, which is connected via cable car infrastructure. Winter access includes skiing routes across the Theodul Glacier, making the area primarily interesting during the snowy season.

The mountain is shaped by two distinct glacial systems: the Theodul Glacier covers the north face while the Verraz Glacier dominates the eastern slope. This double glacial formation creates contrasting conditions on either side of the summit.
