The hilly areas of Rajasthan provide several days of ideal trekking   opportunities. The Mewar belt with the Udaipur-Kumbhalgarh-Chittaur combine, or   the area around Mount Abu, or the Sariska-Alwar-Amber belt is best for   trekking.
Winter is the best time for trekking, though the monsoon months   provide romantic, green getaways. It is best to trek in a small group, and carry   only basic necessities, since provisions can be bought along the way, but do   ensure a supply of bottled water. Trekkers can choose a camp in the open   countryside, though there are likely to be quaint, personalised hotels available   in most areas. Trekking can be along established routes, though a more exciting   option may simply be to chart one's own trails, moving practically as one   likes.
Lying   in the west of India, the topography of Rajasthan varies from sand-dunes of the   desert to the lofty hill ranges of the Aravallis which makes Rajasthan a   trekker's paradise. 
There are many beautiful meadows, dense forests,   crystal lakes, waterfalls and rivulets meandering through the countryside. One   of the old eat mountain ranges of the world, the Aravallis, extending from   northeast to south-west have some beautiful forest areas. Mount Abu, about 1300   mts. above sea level is an ideal locale. 
Kumbhalgarh   is another area in the Aravallis which is also good for trekking. Kumbhalgarh is   just 90 kms from Udaipur off the Udaipur-Pali- Jodhpur Road. Trek upto the   historic Kumbhatgarh fort. There is also a wildlife sanctuary. The famous Jain   temples of Ranakpur are close-by.
Trekking routes in Mount Abu,   Kumbhalgarh and Rawali Tatgarh are not restricted to any particular area. The   entire mountain system offers exciting trails which originate at starting points   spread over the entire length and breadth of the Aravallis. OneCan trek from Abu   Road to Guru Shikhar (highest peak of Aravali),Thandi Beri to Kumbhalgarh fort   or Ranakpur to 
Rawali Tatgarh 
The best time for trekking in   Rajasthan is from November to February. But mid-September to end of October and   March-April is also pleasant. There is ample space for camping under starlit   nights or in the Dak Bungalow and Forest Rest House depending on the tourist's   preference.
