Arrive Manali early morning; many hotels have late-night/early-morning arrivals but confirm early check-in or request luggage storage and nap before sightseeing.
Visit the unique wooden Hadimba Temple set in a tranquil cedar forest — culturally significant and photogenic; temple grounds open early to late afternoon (approx 6:00am–6:00pm).
