Coorg is extremely rugged across most of its land area. There are many summits to conquer and many jungles to trek. But preparation and precaution is always advised before you plan any trekking trip in Coorg. Below mentioned are information & precautions that everyone must take into consideration if they plan to hike across Coorg's mountains and forests.
Trekking in Winters:
Temperatures near the summit during winters can drop to freezing levels after sunset, making hypothermia a possibility.The higher you climb, the colder and windier it will get.
Trekking in Summers:
During summers, sunburn is a risk. Heat stroke can also set in.

Few essentials to carry while trekking:
While trekking; take plenty of water, food, a flashlight, hat, sunscreen in summers and warm clothing in winters and rainy season.
Take the following precautions while trekking in Coorg, during summers:

  • Drink water - lots of it. Make sure you carry your own water bottle while on trail.
  • Stay out of of direct sun. Wear hats and caps as well as sunglasses.
  • Wear sunscreen.
  • Avoid the hours between 10 am to 2 pm, when the the rays of sun are strongest.
  • Enjoy an early morning hike, then rest in the shade that afternoon.
  • Do not skip food, make sure your provide your body proper nutrition.
Trekking in the Mountains:There is very less vegetation in mountainous and highland areas of Coorg, so finding your way around is not an issue.But note that; most of the treks to mountains involves arduous steep climb to the summit. Highland trekking is only recommend for people in top health condition. Bad weather and poor visibility can become an obstacle. You shall hardly encounter any settlements and people . If you get injured, getting you back to the base camp can become an arduous task in itself.
Trekking in Lowland Coorg:

Larges tracts of Coorg's lowland areas remain untouched by any human activity, a sizable portion is reserve forest. The unspoiled remoteness is a special attraction of lowland trekking in Coorg. But trekking is such areas also has its own dangers.If you are going alone ( without a local guide ), there is little chance of getting help.

Routes disappear in the dense jungle and without a guide, you can easily become lost.
Getting to some treks and back again can be an adventure in itself due to Coorg's appalling conditions of many roads.In rainy season, many roads become inaccessible. In monsoon the trails become infested with leeches and difficult to climb.
Trekking Alone:
Its not worth the risk. If you get injured, you are on your own. You can also become an easier target for robbers and wild animals.

Trekking for women:
Trekking alone is not recommended for anyone. Even a group of women together is no guarantee of security and safety.
Not Recommend.
Trespassing:
Many trekking routes pass through plantations/private property. The last thing the plantation owner would not like to tolerate is a bunch of boisterous trekkers en route plucking coffee, pepper, cardamon, etc. Don't do that. Some planters may charge a nominal fee for using the route through their plantations, be ready to pay up.

    Gudalur is a picturesque green valley on the way from Mysore to Ooty with a population of 32,605 (1991 census). It is a gateway to three states, Tamil Nadu, Kerala and Karnataka lying equidistant from both Kerala and Karnataka. Though the history of the name has been lost, it is the place where all of the three states' boundaries meet. Some even say the name originated as 'Koodal'(Joining)in Tamil and 'Ooru'(Village),and Goodal+uru as a mysterious place. As the town is located 50 km from any other nearby bigger towns, Ooty, Sulthan Bathery an Gundalpet it can very well be called as the Joining-Place or Point.
Tea plantations dot the whole region, and the regional economy is heavily dependent on the tea industry. However, this is a place rich in flora and fauna with a variety of hill crops, though lower altitude crops such as paddy and coconut also flourish here. This area was an offspring to the exploration done by the British during the pre-independence period to cultivate tea. Various large companies own tea estates in the region. From the 1960s onwards, the region saw pioneering settlers moving in from neighbouring Kerala. Later, towards the end of the 1970s, the Tamil Nadu Government also granted refuge to a large number of Sri Lankan repatriates. This considerably changed the demography of the region. Gudalur is a place where one can see people from the two states of Tamil Nadu and Kerala live together cordially.
