Friesland Ridge is a ridge on Livingston Island in the South Shetlands, part of the Tangra Mountains. The summit, Mount Friesland, which rises to 1,700 metres (5,600 ft), is the northwesternmost of the ridge's six main peaks. Its elevation was estimated at 1,684 metres (5,525 ft) by a 1995/96 Bulgarian survey; the present figure was produced by a 2003 Australian GPS survey, and closely matched by the Bulgarian survey Tangra 2004/05.

It is the first or second highest peak of both the mountains and the island along with Mount Friesland. The two are connected by a short saddle of elevation 1649 m dominated by ‘The Synagogue’, a sharp-peaked rock-cored ice formation abutting upon the central summit of St. Boris Peak. The peak is also connected to Simeon Peak by Paril Saddle, and surmounts Huntress Glacier to the northwest and west, and Macy Glacier to the southeast.
Tangra Mountains form the principal mountain range of Livingston Island in the South Shetland Islands, Antarctica. The range had been nameless until 2001, when it was named after Tangra, "the name of the ancient Bulgarian god."
Wörner Gap is a flat saddle extending 3 km in the south-north direction between Friesland Ridge and Bowles Ridge in eastern Livingston Island in the South Shetland Islands, Antarctica. Its elevation decreases from 585 m in the south to 541 m in the middle, and 525 m in the north. The gap separates the glacial catchments of Perunika Glacier to the west and Huron Glacier to the east, and is linked to the east to Kuzman Knoll, a conspicuous landmark in the area. The gap is visited by field parties from St. Kliment Ohridski Base and Juan Carlos I Base and is subject to Spanish and Bulgarian glaciological studies.
