Multifaceted, fascinating, colorful - North India/Rajasthan

For the spontaneous, for the onward traveler, for India enthusiasts or those who want to be... :) Hello dear ones, that India is exactly that, multi-faceted, fascinating and colorful and much more, I experience since mid-October every day. In October I traveled with two friends for two weeks from Mumbai to the southern tip of India. Since November 1, we have been working as volunteers in an Indian hospital. After my assignment, I wanted to explore the north with a group trip, but unfortunately it was cancelled due to lack of participation. Of course, this should not prevent me from exploring northern India, that's why I'm looking for you/you, because in pairs, in threes.... it is simply more fun! Since I was set on the group trip, the travel dates are relatively fixed, on February 13 my flight leaves Aurangabad for Delhi, we could meet there. Or even already in Aurangabad, depending on how your plans are. My return flight to Germany is on 29 February from Mumbai, I could also rebook depending on the itinerary. About the itinerary: Delhi, Taj Mahal, Jaipur, possibly Jodhpur should be included in any case, but actually nothing is fixed yet, so I am open to suggestions. Only further domestic flights I would like to avoid for the sake of the environment, because I have found during my trip through the south that train travel is no problem and especially night trains are optimal for traveling through India. During the trip to the south we always stayed in hotels, depending on your wishes we can also try something else, but it should be safe and reasonably hygienic. I am happy to find fellow travelers on this way and to share my enthusiasm for this country! Kind regards Caro
