Yes, but Ben Lomond becomes a serious winter mountain from November to April. At 974m the summit regularly sits in sub-zero temperatures with snow cover, verglas (clear ice) on the rocks and cloud that can trap you in whiteout. You need full winter hillwalking skills: ice axe, crampons, navigation in low visibility, and the judgement to turn back.
Ice axe and crampons (both fitted and practiced), B2-rated boots, four seasons of layers including synthetic insulation, full waterproofs, hat and glove redundancy, head torch, map, compass, GPS, bivvy bag, emergency food, and a charged phone with the What3Words app.
Summit temperatures on Ben Lomond typically run 6-8°C colder than the valley. In a stiff wind, wind chill can push the feel-temperature below -15°C. Always check the summit forecast on hillandglen.com before you set out, not the lowland one.
Scottish mountains carry avalanche risk from December through April. Check the SAIS (Scottish Avalanche Information Service) forecast for the relevant region before setting out. English and Welsh mountains carry less risk but aren't immune — windslab on lee slopes is the most common cause.
March often offers the best combination of long daylight, settled weather and consolidated snow. December and January have the shortest days and most unstable conditions. February can be excellent but also the coldest.
