According to me.... You should try to go somewhere in north eastern India as june would be high on mercury, specially try to travel in himachal and you can also opt for nepal
Off the reel just move towards north east states like Himachal Pradesh ( Manali, Kullu, Shimla ) Uttarakhand ( Nainital, Dehradun, Mussoorie, Uttarkashi) Sikkim (Gangtok) and Meghalaya these states and places are perfect for explore with friends....thanx😊
There are many places . Depends upon your starting point and the overall budget.
To name a few :
Coorg , Ooty , Yercaud and Kodaikanal and Munnar in South
shimla , dharamshala , nainital, kasauli , patnitop , gulmarg n north
Tawang , shillong , darjeeling and kalimpong in north east
