I haven't been able to find much information about this, so would be nice to get some feedback from people who have been here.
Being not such big fans of hiking in the cold, my current plan for a trek was to go down to Hetauda from Kathmandu, and camp across Chitwan to Sauraha/Bharatpur. The plan is to do this without a guide. What would camping in Chitwan be like? Is it even allowed? How frequent are tree houses within the national park between the route that could ease the trip if things got hard?
