I went to Corbett twice....
First time I stayed in Corbett Hideaway Resort.... Mesmerising if you are travelling in nov end or dec....
the resort is at river bank and rooms are also river facing with mountains behind them.... magical experience...
second time I went to Karma sitabani resort in Sitabani zone... it's in total interior of the corbett...
a 45 min drive inside jungle and then the resort.... but you won't regret a bit about going there....
totally peaceful and safe.... huge resort with pool as well...
just grab few friends and few scotch bottles and you'll feel energized in 3 days
