Breaking the myth that the toughest treks in India only exist in the Himalayas, Plan the Unplanned presents to you the exclusive list of the most challenging and toughest treks in India –

AMK Trek, Maharastra

Alang Madan Kulang trek, popularly known as AMK Trek, is set in the Kalsubai range of the Shyadris in the Nashik district. The trek is popular among adventure enthusiasts because it challenges endurance at every step and is considered the most strenuous trek in Maharashtra, India.

The trek connects the Alang Fort, Madan Fort, and Kulang Fort. Interestingly, these forts have witnessed centuries of combat and have passed from hand to hand – From the Marathas to the Mughals, back to Maratha, and then to Britishers in 1818. The stairs were destroyed in cannon fire, and hence the tricky way to the top. 

AMK Trek

What comes after traversing through thick forests, walking through confusing trails, climbing straight rocks, covering challenging stretches of water is the breathtaking view, two stunning caves, a temple, 11 cooling water cisterns, ancient writings on the walls, astronomical withholdings, and a flat plateau to rest and soak in the history.

Additionally, the top overlooks many prominent peaks and reservoirs, including the Kalsubai, Vikatgad, Vishramgad to the North East, Ratangad, Harishchandragad, Sandhan Valley, Ajobagad, Dangya Pinnacle to the South, and Bhandardara to the South East —  just to name a few!

Meesapulimala is the second highest peak in western ghats in the Idukki district of Kerala. This is a trek through eight hills, passing through the shared border of Tamil Nadu and Kerala. It is an 8 KM trek from Rhodo Valley, but hiking the mountains from the Silent Valley challenges persona and manifests many forms. It takes one from the lush green valleys, high altitude grasslands, beds of lovely Rhododendrons, the shadow of tea estates to the peak which resemble very much to a tiger’s face – and hence the name.  “Meesa” means mustache, “puli” means tiger, and “mala” means hill.


The best part of the trek is encountered with rising and setting sun. Moreover, the candy clouds hanging above lush greenery, the cool breeze wafting in the atmosphere, and the sun rising from the horizon hold anyone by charm. The path is confusing, and in the marshy areas, leeches are waiting, especially to suck blood. So beware!

Bandaje Falls Trek, Karnataka

Bandaje Falls Trek - Plan The Unplanned (4)

Located in the Charmadi ghat of the Western Ghats in the Belthangady taluk of Dakshina Kannada district, Bandaje Falls make their way from the mountains and fall straight into the unknown. What makes this trek different and unique from others is that when it falls, you mesmerize it from a distance. While falling, it covers forests, meadows, river streams and finally joins the river Netravathi as a tributary. 

Undoubtedly, beauty is breathtaking, but since the entire trail is continuously changing, a trekker must always anticipate the worst and keep an eye. Here are the following things to keep in mind –

  1. The slippery way during monsoons
  2. You will be in the company of leeches.
  3. There are steeper sections after the Ballalarayana Durga Fort from where one has to descend to the fall’s mouth. Be careful of the trail and some tricky areas.
