Best Time to Travel - You can plan your travel in Rajasthan between July to March; the best time however is between Oct-Feb, except Mount Abu, which is the only hill station in the state.
Food - If you plan to try Rajasthani cuisine, make sure to ask specify your spice preference. Rajasthani food is traditionally very hot and spicy. Most of the eating places including some budget hotels serve continental meals as well. A word of advice – if you have a tender digestive system – avoid experimenting with the traditional food.
Sun - The sun can be extremely harsh especially after rains in the Thar Desert. It is advisable to carry sun block lotions, as these are not available locally.
Water – Carry mineral water bottles if you’re not used to Indian tap water. Buy mineral water from big stores as a lot of spurious stuff is in circulation in the markets.

Familiar Tourist Traps

Pushkar stands out as an exception in this otherwise safe state. At Pushkar, one has to be careful of touts in the garb of priests who might harass you for a few rupees, cents or dollars.
Advice – be firm and if required seek help from the police station if things get out of hand.
Single women should not go out alone with local men or camel drivers.
Some of the smaller jewellery shops may be selling imitation jewellery, where the stones or metal may not be real. It is a good idea to buy jewellery only from big or known stores even though they might be slightly more expensive.
