I highly recommend winter hiking in the whites but you have to prepare/educate. Start with north pack monadnock or something under 5 miles (Welch Dickey is awesome but has lots of exposed slab that can be slippery). Preferably first with people or groups that have experience (MITOC , AMC, etc). Make sure you have proper layers (moisture wicking bade, insulating like down, then shell), waterproof hiking boots, headlamp (I prefer two or at least an extra set of batteries), map, gators, micro spikes, balaclava or buff wrap for your face, check weather and higher summits forecast, extra water (that you can keep from freezing), hand warmers, extra food, a contact that knows your plans/trails if your solo and can call search and rescue if you’re not out by certain time. You probably won’t have cell service. I’ve only needed snowshoes once and did most of the 48 in winter. Ease into it and never hesitate to turn back. Weathers changes happen fast. Always stay on the trail. Remember to look up because it’s the most beautiful. Have fun!
