Day 1:Delhi -
From New Delhi railway station board train for Swai-Madhopur, (Train no.2904 - 0720 hr-1312 hr) Ranthambore National Park. You will reach by afternoon. You cantake a Jeep safari in the evening and try luck in spotting the Tigers. 😊
Day 2&3: Ranthambore - Jaipur - Drive to Jaipur from Ranthambore in the morning (145 km - 3 hr), Spend one and half day in Jaipur. Take the overnight train to Udaipur
Day 4&5- Spend two days in Udaipur. On day 5 you can take an overnight bus from Udaipur to Jodhpur, it will take about 8 hours.
Day 6&7 - Two days in Jodhpur, you can either take an overnight train or fly back to Delhi. Train would be better as that would be an overnighter , the flights take off in the afternoon, so that would be a waste of a day.
Another Option is :
Day 1- Drive to Ranthambore. I presume you are travelling from Delhi. Day 2 early morning drive off to Jaipur.
Day 2&3 : Jaipur
Drive to Jaipur, the pink city, so named because of the pink colored buildings in old city such as the famous Palace of Winds.
Day 4 &5 : Udaipur
One of the most charming places in Rajasthan is the city of lakes, Udaipur. On a romantic boat ride on Lake Picchola enjoy the beautiful panoramic view of the City palace complex, the Lake Palace and the Jag Mandir.
Day 6&7 - Jodhpur
OR Else u could do :
Day 1- &2 Flight to Jodhpur from Delhi, there are two flights from Delhi one at about 10 am and the other at 1pm, but both would get you there by late afternoon as the morning flight has a stop over.
Day3 &4- Drive to Udaipur ( 256 kms from Jodhpur) or fly ( two flights from Jodhpur to Udaipur in the afternoon about 2 pm. Flight time is about 1 hour.
Day 5&6- Fly to Jaipur ( 2 flights in the morning 8 am and 9am, flying time about 1 hour but depends on whether the flight is non stop or not) or drive Jaipur 295 kms from Udaipur. Day 6th Afternoon you could move to Ranthambore , a drive of 130 kms.
Day 6 ( afternoon and day 7- Ranthambore and drive back or take a bus back to Delhi
