Yes, Manali is safe for couples and honeymooners, even in winter. In fact, it’s one of the most popular honeymoon destinations in India. If you’re staying in a resort slightly away from the main town, it’s better to arrange taxis through the hotel rather than hailing random cabs at night. Most riverside resorts are secure, but roads can get slippery during heavy snowfall in December, so avoid late-night drives. Couples usually enjoy Mall Road, Solang, and Atal Tunnel without safety issues. Just plan your outings so you’re back before midnight, and you’ll be fine.
