Includes FREE planning and background information. The Bernese Oberland should come with a health warning – caution: may cause trembling in the north face of Eiger, uncontrollable bouts of euphoria at the foot of Jungfrau, 007 delusions at Schilthorn and A-list fever in Gstaad. And it’s highly addictive. Mark Twain wrote that no opiate compared to walking through this landscape (and he should know), but even when sober the electric-green spruce forests, so-big-they’ll-swallow-you-up mountains, surreal china-blue skies, swirling glaciers and turquoise lakes seem the products of hallucination.
