Your hotel may offer you a camel safari service and the touts in the market streets can be very persuasive, but I would personally do some shopping around before picking a company.
Although the whole of Jaisalmer offers a desert safari service of some kind, I would do some research online, double check the prices, what’s included and if it’s definitely what you want.
Don’t make a mistake of picking the first one as you may find that it’s overpriced, or badly organised.
Prices can vary greatly depending on the service and where you’re staying.. For example, if you’re staying in a 5* resort, you can obviously expect a 5* price. Furthermore, if you’re looking to spend a night out under the stars on the dunes, you can expect to pay a lot less than a luxurious camping/glamping experience.
My hotel, Helsinki House, offered two types of safari. One was a backpacker priced sleep on the dunes with a camel safari, transfer and meals for around 1800 rupees (£20). The other was a more tailored camping experience for around 3-4000 per person (£35-£40)
