For the shortest practical journey, book the earliest reasonably priced Mumbai–Dehradun flight you can find for 6 November, ideally one that lands by late afternoon. The flight itself may take around 2–3 hours when a nonstop service is operating, but allow 3–4 additional hours for reaching Mumbai Airport, check-in, security, baggage collection, and the onward transfer. Depending on where you start, airport travel can take 45–120 minutes; leave Mumbai with at least two hours before departure. From Jolly Grant Airport, pre-arrange a taxi to central Dehradun—normally 40–60 minutes and roughly ₹900–₹1,500. If fares are excessive or no suitable flight is available, an overnight train is more economical but usually takes about 24–30 hours and may not meet the late-6-November arrival goal.
After checking in, browse Paltan Bazaar for about 45 minutes, mainly for snacks, toiletries, or other essentials. Walk onward to Ghanta Ghar, the central clock tower, in around 10–15 minutes; allow 30 minutes to see the landmark and absorb the evening bustle around the market streets. These central areas are lively, but keep your luggage and phone secure, and use an auto-rickshaw or app cab if you would rather not walk after a long journey.
Have dinner at Ellora’s Melting Pot on Rajpur Road, allowing 1–1½ hours and approximately ₹500–₹900 per person. Robber’s Cave (Gucchu Pani) in Anarwala should be treated as optional only if you arrive early enough for daylight: it is about 1.5–2 hours by local taxi, but the cave and uneven streambed are unsuitable after dark. From central Dehradun, budget roughly 25–40 minutes each way depending on traffic; if your flight lands late or baggage and airport transfers run over, skip it rather than attempting an evening visit. Its usual visiting window is daytime, and timings or access can change, so confirm locally before setting out.
