Please confirm: do you want a one-day round trip from Shirdi, or a 1‑night/2‑day trip staying in Nashik/Trimbak? Also tell me your transport (private car/taxi/self-drive/train) and fitness level for trekking (easy/moderate/steep). With that I will produce a full, timed plan with verified opening times and precise distances.
I can prepare (A) a full one-day early-start itinerary covering Trimbakeshwar + a short trek to Harihar/Anjaneri and a Nashik stop, or (B) a relaxed 2‑day plan with overnight in Nashik and vineyard visit. Tell me which you prefer and whether you need hotel or taxi suggestions.
