The High Coast (Swedish: Höga Kusten) is a part of the coast of Sweden on the Gulf of Bothnia, in the Ångermanland province of northeast Sweden, centered in the area of the municipalities of Kramfors, Härnösand, Sollefteå and Örnsköldsvik. It is notable as an area for research on post-glacial rebound and eustacy, in which the land rises as the covering glaciers melt, a phenomenon first recognised and studied there. Since the last ice age, the land has risen 300 meters,^[1] which accounts for the region's unusually tall cliffs. The High Coast is part of the Swedish/Finnish High Coast/Kvarken Archipelago UNESCO World Heritage Site because of its exceptional geology and unique example of isostatic rebound.^[2]

The relief of the High Coast is that of a large scale joint valley terrain that dissects uplifted remnants of the Sub-Cambrian peneplain.^[3][4]

During the Ice Ages of the past 2-3 million years, the High Coast was repeatedly covered by continental ice sheet, including the Fennoscandian ice sheet until roughly 9600 years ago.^[2][5] When the glaciers retreated from the High Coast, the ground, which had been compacted by the weight of the ice sheet, went through rapid uplift, a process known as isostatic rebound. This rebound cause uplift of roughly 285 meters, the highest known isostatic rebound on Earth.^[2] The region is still rising, on the order of 8 mm per year.^[6] Remains of the former shorelines can be seen along the High Coast.^[5]

Some of the fish species found in the High Coast are relict species from the most recent ice age, including the Fourhorn sculpin.^[6] Other animal species resident to the high coast include brown bears, lynx, and moose.^[5]

The area known today as Höga Kusten has historically been known as the Ångermanland Coast.^[7][8] In 1974, the term High Coast (Swedish: Höga Kusten) was coined in connection with a report on the area.^[9]

In 2000, UNESCO put the area on the World Heritage List:

"The High Coast site affords outstanding opportunities for the understanding of the important processes that formed the glaciated and land uplift areas of the Earth's surface."^[2]

In 2006, the High Coast was joined with the Finnish Kvarken areas.^[2] The World Heritage Site ranges from the High Coast Bridge (Swedish: Högakustenbron) in the South to Skagsudde in the North.

The most popular places to visit in the High Coast of Sweden are Skule Mountain, Skuleskogen National Park, and the islands Ulvön and Trysunda.^{[citation needed]}

The High Coast of Sweden is considered to be excellent for hiking and has been cited as one of the best hiking regions in Sweden.^{[citation needed]}

Both outdoor magazines (such as Utemagasinet and Outside) and daily newspapers (such as Svenska Dagbladet) rank the High Coast Trail as one of the best of Sweden's hiking trails.^{[citation needed]}

The High Coast Trail is a 128-kilometer long trail along the High Coast. For day hikes, Skule Mountain and Skule National park are popular. The High Coast Hike (Höga Kusten Hike) is an annual event considered suitable for both experienced and new hikers.^{[citation needed]}

The Höga Kusten Bridge is located in the region, while there are a number of picturesque islands and fishing villages in the area.
