Great idea. Here’s a practical road-route plan to visit Sankeshwar (Sankheshwar), Patan (Gujarat), and Ahmedabad starting from Mumbai. I’ve kept it simple and logically sequenced to minimize backtracking.

Overall plan (by road, approximate distances)

• Mumbai → Sankeshwar (Karnataka): about 520–570 km, ~9–11 hours depending on traffic and stops.
• Sankeshwar → Patan (Gujarat): about 320–380 km, ~6–8 hours.
• Patan → Ahmedabad: about 120–140 km, ~2–3 hours.

Day-by-day route (suggested)

• Day 1: Mumbai to Sankeshwar

- Route idea (main highways): Take the NH from Mumbai toward Pune, then head west via NH 65/NH 4 corridor toward Kolhapur, then continue toward Belgaum region and take local connectors to Sankeshwar. - Key towns to watch or stop for rest/food: Pune (optional), Satara, Kolhapur, Belgaum, Nipani area. - Overnight suggestion: Sankeshwar or nearby Belgaum.

• Day 2: Sankeshwar to Patan (Gujarat)

- Route idea: From Sankeshwar head north toward Belgaum, then continue via NH toward Hero or Navsari corridor into Gujarat; move southwest to Patan. - Key towns to watch: Belgaum again if you skip a night there, then border crossing into Gujarat near Bardoli/Chikhli flow areas, then Patan. - Overnight suggestion: Patan.

• Day 3: Patan to Ahmedabad

- Route idea: From Patan, take the road toward Mehsana and then join NH 48/SH routes to Ahmedabad. - Quick note: The Ahmedabad leg is straightforward on NH/major state highways with good road quality.

Practical tips

• Best time to travel: cooler parts of the year (late Oct–Feb) if you want a comfortable drive; monsoon months can slow you down with rain.
• Fuel and breaks: plan 2–3 long breaks each leg. Fuel stations along NH corridors are frequent in Maharashtra and Karnataka; Gujarat has good coverage as you approach Ahmedabad.
• Vehicle readiness: check tires, brakes, and coolant; carry a basic tool kit and a spare tire.
• Jain visits: If you’re visiting temples en route, note timings in major towns (Belgaum region has several Jain centers; Patan/Ahmedabad also have notable temples).

Notes

• Distances and times vary with traffic, tolls, and chosen exact starting/ending points in Mumbai, Sankeshwar, Patan, and Ahmedabad. If you share your intended travel date, vehicle type, and preferred start time, I can tailor exact stop points, approximate drive times, and tolls.
• If you’d like, I can also provide a simple turn-by-turn style plan with the most common highway numbers for your travel date.

Would you like me to refine this with exact highway numbers and place-by-place stop suggestions once you tell me your travel date and how many hours you’d like to drive each day?
