About This Route
Lake Silvaplana in the Upper Engadine valley of the Swiss Alps offers pristine, glassy waters ideal for stand-up paddleboarding (SUP). This high-altitude lake at 1,811 meters above sea level stretches 4 kilometers long and up to 1 kilometer wide, bordered by the majestic Piz Corvatsch and Piz da la Margna peaks. Popular routes include the calm paddle from Silvaplana village along the northern shore to the Isola peninsula, or a loop around the lake's reed-fringed edges for birdwatching. Winds often pick up in the afternoon due to thermal effects in the Engadin, making morning sessions best. This spot draws beginners and intermediates, but always respect Swiss navigation rules treating SUP boards as rowing boats under federal shipping regulations.
Safety Considerations
Cold water temperatures hover around 10-15°C even in summer, risking hypothermia within minutes of a fall; always paddle with a buddy and inform someone onshore of your route. Sudden Foehn winds can whip up 2-3 meter waves quickly, so monitor forecasts from MeteoSwiss. Avoid river mouths like the Inn River inlet where whirlpools and strong currents form; check water depth with apps like Navionics. Boat traffic from sailboats and ferries increases near Silvaplana harbor; stay 50 meters clear and wear high-visibility gear. Invasive species like quagga mussels threaten these alpine lakes, so clean your SUP board with hot soapy water before and after use, following Swiss Invasive Species Centre guidelines. SUPs require a leash at all times, as your board serves as your primary flotation device. In Graubünden canton, life jackets are mandatory for SUP on designated waters per local bylaws.
Essential Gear
Pack a US Coast Guard-approved PFD like the NRS Vapor, coiled ankle leash from Starboard, 10'6" inflatable SUP board such as Red Paddle Co Compact, adjustable carbon paddle, neoprene booties for rocky shores, quick-dry rash guard, and waterproof dry bag with first-aid kit, whistle, and charged phone in a Pelican case. Don't forget UV-protective sunscreen and a thermal hat for high-altitude sun exposure.
