If you have planned to visit Jaisalmer then definitely is the place for camel ride instead of Bikaner but if you are only going to Bikaner then it's OK to have camel ride there.If you are going to Rajasthan then Jaisalmer is must see place,known for one of the best fort,different from any other forts in India or world,because is the only biggest and oldest living fort,(Have been living fort since 1156 A.D.).
There are many travel companies for it,like Adventure of Thar is one among many others.But you may contact me also to discuss about the duration of the ride you are looking for,camel companies are good as per the duration of the ride.
Please feel free to contact me for any single detail.
Thanks
