I personally believe that traveling free is not possible but you can minimise your expenditure while travelling by taking some good decision. Make sure before going to any destination you do some research about the places in order to save money.
There are many places where you can experience clouds below or closed to you..
But to witness the best ,try any places from the Himalayan ranges from Uttarakhand or Himachal like ;
Uttarakhand :- Kedarkantha, Madhya Maheshwar (One of the Panch Kedar temple), Tungnath - Chandrashila, Satopanth - Swargarohini, Har ki Dun, Gaumukh- Tapovan etc..
Himachal Pradesh :- Mani Maheshwar ( the invincible peak), Hampta Pass-Chandratal, Triund, Roopkund etc ...
Bangalore to Mysore, Mysore to Wayanad, Wayanad to Ooty, Ooty to Palakkad, Palakkad to Munnar, Munnar to Kochi, Kochi to Alleppey, Alleppey to Kovalam(Trivandrum), Kovalam to Ponmudi. Try this route. You can explore all the places.
If you have experience with treking in ice then no need to book through travel group... nd if you are going 1st time or alone or with 1 or 2 person... better go with travel group. you will enjoy the treking.
