Waterfalls and peaks are classic UPSC mapping items, tested on superlatives and on the river/range each is linked to. The highest waterfall in India is Kunchikal Falls (Karnataka, ~455 m); the highest plunge (single-drop) waterfall is Nohkalikai (Meghalaya, ~340 m); Jog Falls (Sharavathi River, Karnataka) is the most famous segmented plunge fall. Among peaks, Kangchenjunga (~8,586 m, on the India–Nepal border) is the highest peak in India, while Nanda Devi (~7,816 m, Uttarakhand) is the highest peak lying entirely within India. K2 (8,611 m) is in Pakistan-occupied Kashmir, so it is not counted as India's highest in official geography.

Don't confuse: "Highest waterfall" (Kunchikal, total height) vs "highest plunge / single-drop" (Nohkalikai) vs "most famous" (Jog). And for peaks: "highest in India" (Kangchenjunga, border) vs "highest entirely within India" (Nanda Devi). These are textbook UPSC traps.

Note: Meghalaya (Cherrapunji/Mawsynram belt) hosts a cluster of the tallest plunge falls because of extreme orographic rainfall — a good place to link climate to landforms in Mains.


Highest Mountain Peaks of India (verified)

PeakHeight (m)Range / StateUPSC Angle
Kangchenjunga8,586Sikkim (India–Nepal border)Highest peak in India; 3rd highest in the world
Nanda Devi7,816Garhwal Himalaya, Chamoli, UttarakhandHighest peak entirely within India; Nanda Devi NP (UNESCO World Heritage)
Kamet7,756Garhwal Himalaya, UttarakhandNear the India–Tibet border
Saltoro Kangri7,742Saltoro Range, LadakhNear the Siachen region
Saser Kangri7,672Karakoram, Ladakh
Mamostong Kangri7,516Karakoram, Ladakh

Exam trap: K2 (Godwin-Austen, 8,611 m) is the highest point on the Indian subcontinent but lies in Pakistan-occupied Kashmir, so it is not treated as India's highest peak. India's highest is Kangchenjunga; highest entirely within Indian territory is Nanda Devi.

KeralaAnamudi (2,695 m) — highest peak in South India / Western Ghats

Pointer: Anamudi (Kerala, 2,695 m) is the highest peak in South India and in the Western Ghats — frequently confused with Doddabetta (Nilgiris). Anamudi is in the Eravikulam NP (Nilgiri Tahr).


Quick UPSC Pointers

  • Kunchikal = highest waterfall; Nohkalikai = highest plunge; Jog (Sharavathi) = most famous.
  • Dudhsagar = on the Mandovi, Goa–Karnataka border, Konkan railway.
  • Kangchenjunga = highest peak in India (border); Nanda Devi = highest entirely within India.
  • K2 is in PoK — not India's official highest.
  • Anamudi (2,695 m) = highest in South India / Western Ghats; Doddabetta = highest in the Nilgiris.
  • Cross-reference the Rivers and Mountain Passes mapping pages.
