Start before dawn from Khambhalia and drive roughly 1–1.5 hours to Jamnagar Airport; arrange your road transfer in advance and leave extra time for airport check-in. The flight to Mumbai takes about 1.5 hours, but confirm that a suitable same-day flight is actually operating before committing to this plan. From Mumbai airport, allow around 45–90 minutes by prepaid taxi or app cab to reach Colaba, depending on traffic.
After arriving, spend about an hour at the Gateway of India, taking in the waterfront and the bustle around the landmark; the public area is free to visit. Then walk a few minutes along Colaba Causeway to Cafe Mondegar for lunch. Budget about ₹500–₹1,000 per person, and check its hours on the day—popular tables can be busy around lunchtime.
Take a taxi from Colaba to Marine Drive—allow roughly 20–40 minutes in traffic—and enjoy an easy hour-long seafront walk before heading to the airport. For the return, fly from Mumbai to Jamnagar, then continue by pre-arranged road transfer to Khambhalia; allow about 3–4 hours from the Mumbai airport through the flight and onward drive, plus check-in and transfer time. Same-day return flights may not line up, so verify both legs before setting out and be prepared to stay overnight if needed.
