We reached Gir in the morning, it is overnight travel from Ahmedabad. We stayed at HOTEL SHYAM HOME which is very affordable and very nearer to Sinh sadan, the place where the safari starts. If you are with family you can opt resorts in Sasan gir, its costs you much but your stay will be memorable.
Use this link to book your safari at gir, i recommend you to book before one month as you will not get slots in summer or winter season because of tourists. >> http://www.girnationalpark.in/jeep-safari-in-gir.html
After booking you will get a mail for Gir forest about the payment procedure. They will charge you about 5300 rupees per jeep upto 6 people.
I recommend you to opt Morning slots rather than afternoon ones, There is 90% chance to witness the pride of lions in early morning slots, where as in afternoon slot (4pm - 7pm) you may have 50% chances to witness lions in between 4pm to 6pm and 80% of chance to witness after 6pm. And this is all about jeep safari.
Apart from jeep safari there is another type of safari called Devalia safari, this trip takes place in Devalia zone where you have 100% chance of seeing lions, as it is an enclosure just like we see in zoo. In devalia safari you have buses but not jeeps, timings will be from morning 7AM to 11AM, 3PM TO 5PM. Ticket costs about 150 per head, 190 during weekends for indians. 2800 on regular days and 3500 on weekends for foreigners.
