6. Camping, trekking and climbing gears: If you are an adventure driven person and love outdoor touring then a onetime investment in such stuff makes sense. But if you are one of those who take a small nap away rarely from office and chills once in awhile by tenting and trekking in cool places then investing in gears like this will be a dead investment. Indian travel and tourism industry has taken a big boost and has many facilities in making their tourists comfortable. Among them is the renting of camping and trekking gears. The rental gears are made available at places which are very well known for camping. The rental gears are available with a rental deposit and a charge per day. Again you have to work out the math and think which is more viable.
