I do agree with most of the early reviews that one will not find as much animal as we see in a Zoo but thats the thing makes it a National park. Here Animals are not kept in cages and hence they are the owner of their own will and it all depends on their mood or climate whether they come out of their den or not.
One should not assume that every 10 mins you will see a Animal here as it is not possible to cover 800 Kms of area in one day. Still if you want to better your chances to see an animal then best thing you can do is to stick to some water resource.
The climate and greenery here is awesome, the wind is utterly fresh and this will burst out your stress and you will feel very relaxed. This is really a nice place and one of the best safari destination in India. The place is easily accessible by Rail and Road. Nearest Rail Station is Alwar and nearest Bus station is also Alwar. The nearest Airport is Gurgaon as well as Jaipur. This is one of the best place to visit in Rajasthan.
