For more than two thousand years, Buddhist literature has spoken about a mysterious sacred lake named Anotatta (also called Anavatapta).
It is described in deep detail in the Pāli Canon — its water, mountains, climate, and even the rivers that flow from it.
Yet, its real-world location remains unidentified.
This article brings together:
- Pāli Canon descriptions
- Indian geographical claims
- Sri Lankan mountain evidence
- Classical sources like Pliny
- Geological findings
- Historical paintings
- And journey paths of the Buddha
while keeping the unresolved aspects open for ongoing research, not forced into conclusions.
1. How the Pāli Texts Describe Anotatta
Across the Nikāyas and Commentaries, the lake is described with consistent physical features:
Core Pāli Features
- Located in the Himavanta mountain region (cool, misty, forested highlands)
- A mountain-surrounded lake, ringed on all four sides
- Waters described as:
- Clear
- Blue
- Cool
- Not heated by the sun
- Fed by underground springs
- Four rivers flow out from its four sides
- Steep cliffs and high ridges around the lake
- Associated with:
- Hermit mountains
- Nāgas
- Rare herbs
- Forested slopes
- Visited by Pacceka Buddhas, previous Buddhas, and arahants
Size
Commentaries mention 50 yojanas, but the length of a yojana varies, and may be symbolic.
👉 So the actual physical size remains an open question.
Buddha’s Journey
Texts state the Buddha:
- Visited Kurudīpa
- Then reached the sacred lake
- Then traveled to Mahiyangana
The exact geography and distance remain open for further study.
2. The Indian Identification — Where It Is Claimed to Be
Later Buddhist tradition (especially from North India and Tibet) places the lake near:
- Mount Kailash
- Manasarovar
- Rakshastal
- High Himalayan glacier lakes
These identifications came later, influenced by the Kailash tradition and Chinese pilgrim accounts.
But the question remains:
❓ Do any Himalayan lakes match the Pāli description?
Let’s check objectively.
3. Why the Indian Locations Do NOT Match the Pāli Descriptions
❌ A. No Himalayan lake sends rivers to 4 directions
Most Himalayan lakes are glacier-fed and drain in one general direction (southward).
The Pāli lake sends four rivers in the four compass directions.
This hydrology does not occur in Tibet or the Indian Himalayas.
❌ B. Glacier lakes = frozen, stagnant, low-oxygen
Pāli texts say the lake is:
- Cool but NOT freezing
- Perfectly drinkable
- Sapphire-blue and running
- Never stagnant
Himalayan glacier lakes do not match this behavior.
❌ C. Himavanta ≠ Himalaya
In Pāli:
- Hima = cold, misty, dew-filled
- Vanta = forested region
Not necessarily snow-ice mountains.
This fits Sri Lanka’s highlands far better than the icy Himalayas.
❌ D. The Buddha’s travel path cannot be placed in India
Kurudīpa is described as an island.
Mahiyangana is in Sri Lanka.
There is no possible Indian route that fits:
Kurudīpa → sacred lake → Mahiyangana
❌ E. No Indian archaeological or cultural tradition of this lake
There is no:
- Local legend
- Mural tradition
- Geographic name
- Classical Indian record
that preserves the memory of a sacred mountain lake with four outflowing rivers visited by Buddhas.
4. The Sri Lankan Locations That Match the Descriptions
Across Sri Lanka, several ancient highland areas match elements of the Pāli description.
A. Peak Wilderness (Sri Pada region)
- Mist forests
- Cliff edges
- Multiple rivers
- Old hermit caves
- Indigenous traditions of sacred lakes
B. Knuckles Range / Dumbara Valley / Lakegala
- Steep mountain walls
- Sacred folklore
- Ancient settlements
- Multi-direction river origins
C. Horton Plains — The strongest match
The clearest real-world geographic match is Horton Plains, with:
- High plateau at 2100m
- Surrounded by mountains on all sides
- Crystal-clear springs and basins
- Steep escarpments (World’s End, Baker’s cliff)
- Birthplace of four major rivers (north, west, south, southeast)
- Ancient forest and healing herbs
- Caves and monk settlements in nearby areas
- Inaccessibility in ancient times
- Murals in old Kandyan temples depicting Anotatta-like lakes
This alignment is remarkable.
5. Why Horton Plains Fits the Pāli Lake Better Than India
A. Scientific Evidence
Geologists have confirmed:
- Horton Plains was once a large ancient lake
- Sediment cores show lacustrine layers
- A natural dam broke thousands of years ago
- The drainage carved:
- World’s End cliff
- Belihul Oya gorge
- Downstream river systems
This matches the hydrology described in the Pāli texts.
B. Pliny the Elder (1st Century CE)
Pliny writes:
- In the interior of Taprobane (Sri Lanka)
- There is a great lake
- From which two large rivers arise in opposite directions
Some manuscripts mention three and four rivers.
This is a direct ancient reference to Sri Lanka.
C. Cultural Evidence
Temple murals from the Kandyan era depict:
- Oval lake
- Four-direction flows
- Mountain rings
- Trees, elephants, hermit caves
- Similar to Pāli Anotatta imagery
These murals are typically Sri Lankan, not Indian.
6. Pāli Stories Connected to the Lake — Still Open for Research
Size
The 50-yojana measurement remains unclear.
Different eras used different values.
Scholars treat this as non-literal or symbolic cosmology.
Buddha’s Journey
Kurudīpa → Lake → Mahiyangana
Sri Lanka’s geography fits this flow,
but the exact distances are still studied.
Cosmological Symbolism
References to:
- Nāga palaces
- Jewelled mountains
- Perfectly pure water
could contain symbolic meanings mixed with geographic memory.
This area is still being researched.
7. Summary of the Evidence (Neutral, Scholarly, Non-Conclusion Based)
Strong matches with Sri Lanka
- Mist forest highlands (Himavanta qualities)
- Ancient inland lake (Horton Plains)
- Four rivers flowing in different directions
- Historical memory (Pliny, murals, folklore)
- Buddha’s travel route connections
- Geological lake evidence
Weak matches with India
- No four-direction lake
- Glacier water inconsistent
- Himalayan meaning mismatch
- No archaeological trace
- No matching travel route
Open questions
- Exact size
- Exact travel distances
- Degree of symbolism in descriptions
- Whether the lake represents a real location, symbolic realm, or both
This article presents the information without claiming a definitive identification.

Final Statement
This research presents all available evidence but does not conclude that the ancient Pāli lake is definitively located in any one place.
However, based on:
- textual descriptions,
- travel routes,
- hydrology,
- classical references,
- local tradition,
- and geological findings,
Sri Lanka — particularly Horton Plains — currently offers the closest real-world match, while the Indian Himalayan identifications appear inconsistent with the Pāli Canon.
Certain elements such as size, exact distances, and cosmological layers remain open academic questions for ongoing BuddhaOfLanka research.
