Once both lakes probably formed a single basin, before the deposits of the L\u00fctschine separated them. Above the southern shore rise the famous Bernese giants, and on the horizon the striking pyramid of the Niesen greets the eye, lending the lake its unmistakable backdrop.<\/p>\n<p>Already in the Middle Ages the powerful town of Thun, with its high-towering castle, commanded access to the Oberland and controlled the trade routes into the mountains. Its position at the transition between the Mittelland and the high Alps made the region an early hub. In the 19th century, when Romanticism discovered the Alps, Lake Thun became a popular destination of painters and poets, who found inspiration in the interplay of water, light and mountains. On the northern shore, above St Beatus, towers the famous Beatus Cave, to which the legend of Saint Beatus attaches, who according to the tale is said to have driven out a dragon here. To this day the lake combines gentle shoreline landscapes and old legends with the dramatic ascent to Eiger, M\u00f6nch and Jungfrau, whose world-famous summits rise just a short journey farther into the Bernese Oberland.<\/p>\n<div style=\"background:#221c1a;color:#fff;border-radius:10px;padding:18px 22px;margin-top:28px;\"><strong style=\"font-size:1.08em;\">Related<\/strong><\/p>\n<p style=\"margin:6px 0 12px;color:#d8d2cc;font-size:14px;\">To make your trip run smoothly , our guides and gear tips for this destination:<\/p>\n<div style=\"display:flex;flex-wrap:wrap;gap:10px;\"><a href=\"\/en\/mit-hund-in-den-alpen\/\" style=\"display:inline-block;background:#f25353;color:#fff;padding:9px 16px;border-radius:6px;text-decoration:none;font-weight:600;font-size:14px;\">With your dog in the Alps \u2192<\/a><a href=\"\/en\/hunde-ausruestung\/\" style=\"display:inline-block;background:#f25353;color:#fff;padding:9px 16px;border-radius:6px;text-decoration:none;font-weight:600;font-size:14px;\">Dog gear \u2192<\/a><a href=\"\/en\/packliste-tages-bergwanderung\/\" style=\"display:inline-block;background:#f25353;color:#fff;padding:9px 16px;border-radius:6px;text-decoration:none;font-weight:600;font-size:14px;\">Day-tour packing list \u2192<\/a><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Der Thunersee zwischen Thun und Interlaken ist von mehreren Schl\u00f6ssern ges\u00e4umt, darunter Schloss Oberhofen direkt am Ufer. \u00dcber dem See erhebt sich der Niesen, die markante Pyramide mit der l\u00e4ngsten Treppe der Welt.
