it was a weekend trip from our institute in Kanpur in June 2016. we started our journey on Friday by train from Kanpur to Moradabad and reached Moradabad by 2 A.M. in morning of Saturday. and then took a bus for Ramnagar which is around 81 KM away from it (around 2.5 hours journey), so finally we reached Ramnagar around 5 A.M. and was all set to start our first safari in the morning as we had a good sleep on the train.
Park office normally opens around 6-6.30 A.M (you need to get some official stamp papers to start your safari), so in meantime, we did our breakfast as normally market opens around 4 A.M., buy fruits and other stuff for dinner ( we booked our accommodation in park itself in Jhirna zone and you don't get any eatables in the park ) and booked our jeep as there is a limit on number of jeeps which can enter the park at one point of time.
Tip:-For the greater experience of the park, try to book your accommodation in the park itself and they open booking for the day 2 days prior to it and their site is worse than IRCTC. so try to book it patiently and if possible try your accommodation in Dhikala or bijrani (Corbett has 4 zones) as from these zones you can have elephant safari in the morning.
