Traveller notes on Lake Placid in September
Other months in Lake Placid
Lake Placid's forum is blunt that February is deep Adirondack winter — cold, snowy, and genuinely capable of sudden whiteout squalls that can complicate driving. Regulars point to the upside: cross-country skiing, snowshoeing, dogsledding on Mirror Lake, ice skating on the Olympic Oval and bobsled rides all run in full swing, alongside Main Street's shops, restaurants and the Olympic Museum for a break from the cold.
