Hunched around a horseshoe-shaped bay on Lake Thun, with a medieval castle rising above emerald vineyards, the oft-overlooked town of Spiez makes a great escape. The vibe is low-key but the setting magical, with views to conical Niesen (2362m) and a fjord-like slither of the lake. Its vines yield crisp, lemony riesling and Sylvaner white wines.
