But then also if you have crunch of time and can go only with limited time than plan as follows:-
1. Timing :- First the timing of your trip is most important and as spiti valley is accessible through high mountains and deep vallies which are usually can not travelled throughout the year
so Best time to travel to Spiti valley is from Mid April to August but if one can avoid July month then its good as the heavy rains in the way can cause blockages midway but if you have one or two spare days with you then no problem.
2. Route:- There are two routes which one can adopt to travel Spiti Valley one is via Delhi-Chandigarh-Manali-Lossar-Kaza This route is bit not comfortable for them who are prone to motion and mountain sickness as this route has sharp increase in height along way second is Delhi-Chandigarh-shimla-Narkanda-Rampur-Reckong Peo-Chango-Kaza this route has gradual increament of height alongway As Spiti valley is at almost height of 3800 Meter approx. , so persons prone to Acute Mountain Sickness(AMS) must go for second route.
3. Road condition :- if you are going via second route than you will quite good roads till Rampur except some minor hitches, after Rampur till Kaza the road conditions are not good and you have to be very slow if going on personal vehicles or Bike.. Then come the worst and dangerous roads of the world from Kaza to Rohtang Pass on the return way to Manali and be assured that if you are coming by bus then be ready for rock n roll and if coming by personal vehicle or Bikes and driving than ready to be a perfect driver if you are and if not so good in driving then please these roads are not meant for you to drive and to exploit your skills here. Then from Manali to chandigarh roads are much comfortable except some loops. 4. Accomodation :- while going from chandigarh to shimla routes one can get accomodation per cheap prices to stay at Shimla, Theog,Narkanda, Rampur, Sangla/Chitkul, Kalpa, Reckong Peo,Spillow, Pooh, Nako, Tabo, Kaza, Lossar, Manali. Please be mentally aware that except Shimla, Rampur and Manali all other destinations are small in size and please dont expect five star facilities there. From Kaza to Manali once Lossar get crossed than till Manali, it is very tough to find a stay in between for this around 180 Kms and on the above the road to this distance is very dangerous and risky, except at Chandertaal where one can have their own camping arrangements. so its my humble advice to all that if anyone planning to travel from Kaza to Manali in one day then please either left Kaza as early as possible so that can cross dangerous strech atleast in daytime till Rohtang Pass and after that can easily approach to Manali or have campimg arrangements for Chandertaal and if not then one can find PWD Rest House at Batal and Gramphu/Chhatru but there is no surity that one will get room to stay there as rush is always there, but one can get a small Dhaba type in Chhatru where you can get Bed at 200 bucks to spend night. 5. Food:- one can easily get food throughout the route and there is not at all any problem for it but if anyone is highly choosy and expecting same foods which you can get in plain areas Dhabas and Hotels than i am sorry you are at wrong place and you will get food which can make you feed to stay healthy and alive but not as per your taste. But one can get Maggie, Egg items etc throughout the route. 6. Must Carry:- Temperature in mountains usually dips to sub zero or very low range at night time so one must have proper winter clothing with him while travelling and also rain wears are also must as rains are not frequent but expected anytime so one should have his /her arrangements. as medical facilities are very rare there from Rampur to kaza and Kaza to Manali so one must have atleast minimum required tablets/drugs with them such as pain relief, headache, cold and flu etc Finally the trip to Spiti valley is full of mesmirizing locations and scenes , attractions on the way, here are some pics for you to relate to and the most beautiful thing i noticed in this trip was that while on way from Shimla to Kaza then to Manali to Chandigarh you will go all along the riverside of river Satluj till Kaza and then will come back along river Beas. so please carry good quality camera and storage devices with you to store your memory forever. Note: if anyone want to have clear vision of starry nights than i dont think one will get better chances than this trip as from Kaza to Manali and in between there is Chandertaal and Dhatru where one can halt and have a glimpse of clear starry sky thank you have a nice trip JAI HIND
