Caves of Northeast India: Meghalaya, Mizoram, Arunachal & Other Cave Systems
The caves of Northeast India bring together underground rivers, limestone passages, sandstone labyrinths, prehistoric evidence and sacred spaces. Meghalaya is the region's best-known caving destination, but Mizoram, Arunachal Pradesh, Manipur, Nagaland, Assam, Tripura and Sikkim also have cave sites worth understanding.
This state-wise guide compares their locations, physical character and significance. It distinguishes natural cave systems from rock-cut chambers and sacred caves, while explaining which sites are known for geology, archaeology, biodiversity or pilgrimage.
Quick answer: What are the important caves of Northeast India?
Major examples include Krem Liat Prah, Krem Puri, Mawsmai, Arwah, Mawmluh and Siju in Meghalaya; Khuangchera Puk, Pukzing Puk, Lamsial Puk and Kungawrhi Puk in Mizoram; Menga Cave Temple in Arunachal Pradesh; Khangkhui and Tharon in Manipur; the Mimi caves in Nagaland; Jogighopa's rock-cut caves in Assam; Silachari Caves in Tripura; and the Four Great Holy Caves of Sikkim.

Types of Caves in Northeast India
A cave's name alone does not explain how it formed. Natural solution caves develop where water dissolves suitable rock; other natural cavities involve different combinations of weathering, erosion and rock structure. Rock-cut caves are excavated by people. A sacred cave is identified by its religious use, which does not by itself establish its geological origin.
In limestone terrain, rainwater absorbs carbon dioxide from the air and soil, forming a weak carbonic acid. As this water moves through cracks, it gradually dissolves the rock and enlarges underground passages. Caves, sinkholes, sinking streams and springs can together form a karst landscape. Mineral-rich water entering an existing cave can deposit calcite: stalactites hang from ceilings, while stalagmites grow upward from floors.
Meghalaya's limestone belts, heavy rainfall and underground drainage provide favourable conditions for extensive cave development. However, the plateau contains several rock types, and Krem Puri is associated with sandstone. The region's caves therefore cannot all be explained as limestone features.
For the wider landscape, read about the physiography and geology of the Meghalaya Plateau and the physiographic divisions of Northeast India.
State-wise List of Important Caves in Northeast India
The table is a selected reference list, not a complete cave inventory. A tourism listing confirms a recognised destination; it does not guarantee that every passage is open or suitable for visitors.

Caves of Meghalaya: Khasi, Jaintia and Garo Hills
The caves of Meghalaya are distributed across all three major hill regions. The Sohra–Mawsynram area includes familiar visitor destinations and major scientific sites; the Jaintia Hills contain extensive surveyed systems; and the Garo Hills include important limestone caves such as Siju.
Krem Liat Prah: A Major Limestone Cave System
Krem Liat Prah, also written Lait Prah in some tourism material, lies in the Shnongrim Ridge area of the East Jaintia Hills. Meghalaya Tourism describes a system extending over 34 kilometres, with an especially large trunk passage known as the “Aircraft Hangar”. Its scale makes it an important example of underground drainage and connected cave development.
This is an exploration cave. Its reported system length should never be interpreted as the length of an ordinary tourist walk.
Krem Puri: Meghalaya's Remarkable Sandstone Cave
Krem Puri lies near Laitsohum in the Mawsynram area. Meghalaya Tourism reports more than 24.5 kilometres of passages and identifies it as the world's longest known sandstone cave. That claim refers to a particular rock category, rather than to caves of every type.
The cave contains a complex network of passages and is not a conventional commercial show cave. Exploration requires experienced local guidance and suitable arrangements.
Mawsmai Cave: An Introduction to Cave Landscapes
Mawsmai Cave, near Sohra, is one of Meghalaya's established visitor caves. Its accessible section offers an introduction to limestone formations and underground spaces. Narrow sections, uneven footing and wet surfaces still require care.
A visitor route represents only the section prepared or permitted for public access. It should not be confused with the total extent of the cave.
Arwah Cave: Fossils and Limestone
Arwah Cave in the Sohra area is known for fossils preserved in its limestone. These remains help visitors connect the present upland landscape with the sedimentary environments in which the rock originally formed.
The age of a fossil-bearing rock and the age of a cavity eroded within it are different questions. A very old fossil does not establish that the cave passage itself is equally old.
Mawmluh Cave and the Meghalayan Age
Mawmluh Cave, also called Krem Mawmluh, has international scientific significance. A stalagmite from the cave provides the reference point used to define the base of the Meghalayan Stage/Age, the youngest subdivision of the Holocene.
The formal boundary is dated to 4,250 years before AD 2000, approximately 2250 BCE. The stalagmite preserves chemical evidence of a major climatic change associated with the 4.2-kiloyear event. This is a geological time boundary; it is not the date when the cave formed.
Its scientific role also explains why cave deposits deserve protection. A broken stalagmite can mean the loss of a valuable environmental record.
Siju Cave: The Garo Hills' Bat Cave
Siju Cave, also known as Dobakkol, is a limestone cave in the South Garo Hills. It is particularly associated with bats and underground passages. Its location demonstrates that Meghalaya's cave landscapes extend well beyond the Khasi Hills tourist circuit.
Visitors should avoid disturbing roosting animals. Access near an entrance does not imply that deeper, water-bearing sections are suitable for casual exploration.
Mawjymbuin Cave
Mawjymbuin is another recognised cave attraction near Mawsynram, known for its natural mineral formations. It is a separate destination from Krem Puri. Confirm current access and follow the directions of local custodians before visiting.
Caves of Mizoram: Adventure, Folklore and Heritage
Mizoram's cave destinations are spread across several hill and village settings. Their importance includes physical exploration, oral traditions and evidence of past human activity. Village names are useful location markers because older guides sometimes use outdated or inconsistent district labels.
Khuangchera Puk at Ailawng
Khuangchera Puk lies at Ailawng near Reiek. Mizoram Tourism associates it with Khuangchera, a celebrated Mizo figure remembered for entering a feared cave and demonstrating that two openings were connected. This account belongs to the site's local historical tradition.
Arrange access locally and establish which passage is included in a guided visit. An account of a historic traverse is not a present-day route instruction.
Pukzing Puk
Pukzing Puk, near Pukzing village in Mamit, is listed by Mizoram Tourism among the state's caving destinations. It is a useful example for a state-wise cave reference. Claims that it is Mizoram's longest or largest cave need a comparable survey record; this guide does not assign it that ranking.
Lamsial Puk
Lamsial Puk, near Farkawn, is known for human remains and traditions concerning earlier communities. Its heritage value requires a careful distinction between visible remains, local explanations and conclusions supported by archaeological investigation.
Human remains and associated objects should be left undisturbed. A tourist description alone cannot establish their exact age, identity or cause of deposition.
Kungawrhi Puk
Kungawrhi Puk is located in the hills between Farkawn and Vaphai. Mizoram Tourism connects the cave with the legend of Kungawrhi, a woman said to have been confined there by spirits. Presenting the account as folklore preserves its cultural meaning without treating it as a verified historical event.
Mura Puk and Other Listed Caves
Mura Puk, near Zote village, comprises six caves according to the Champhai district administration. Local folklore connects them with people seeking shelter from a giant eagle. The district account acknowledges uncertainty about their original use.
Mizoram Tourism also lists Lianhela Puk at Lamzawl in Khawzawl district and Reng Puk at Rengdil in Mamit. These broaden the state's cave inventory, although a tourism listing by itself does not establish surveyed length or technical difficulty.
Caves of Arunachal Pradesh: Menga Cave Temple
Menga Cave Temple, also described as Meghna Cave Temple by the Upper Subansiri district administration, is dedicated to Lord Shiva. It is associated with the Daporijo region and attracts devotees, including during Shivratri.
The official district description records a rock cave with two interior tunnels, including sections that become narrow and dark. The temple's public religious function should not be taken to mean that all of these passages are appropriate for visitors.
Menga is best understood here as a sacred cave site. Reliable information on its total surveyed extent and detailed geological formation is insufficient to place it in a length ranking alongside Meghalaya's surveyed systems.
Arunachal's wider mountain setting is explained in our guide to the hills and mountain ranges of Northeast India.
Other Cave Systems and Cave Heritage of Northeast India
Manipur: Khangkhui, Tharon and Mova
Khangkhui Mangsor, near Ukhrul, is a natural limestone cave. The district administration records the discovery of artefacts associated with Palaeolithic culture and its use as a shelter during the Second World War. These give the site both archaeological and more recent historical importance.
Tharon Cave is a recognised attraction in Tamenglong district, while Hundung Mova Cave is another limestone cave listed by Ukhrul district. These sites should be treated individually: the geological description or archaeological findings of one cannot automatically be applied to the others.
Nagaland: The Mimi Cave Sites
The Mimi area of Kiphire district contains limestone caves and rock shelters. Nagaland's Department of Art and Culture documents archaeological work at the Mimi caves, while the Department of Geology and Mining recognises the area's geological interest.
“Mimi caves” is a regional grouping, not a sufficient basis for assuming that every named opening belongs to one connected system. Local identification and survey records are needed to establish those connections.
Assam: Jogighopa and Tularam Cave
Jogighopa's caves in Bongaigaon district are rock-cut chambers. They belong in a discussion of Assam's architectural and religious heritage and should be distinguished from naturally developed karst passages.
Tularam Cave in Dima Hasao is presented by Incredible India as a natural cave attraction associated with Sengya Tularam Senapati. Its chambers and local historical associations add another dimension to Assam's cave heritage. This guide does not assign it an unverified length or national ranking.
Tripura: Silachari Caves
Silachari Caves in Gomati district are recognised as a Biodiversity Heritage Site. The National Biodiversity Authority highlights their importance as habitat for threatened cave bats.
The site's significance is primarily ecological in this comparison. Heritage designation does not itself mean that the caves operate as a visitor attraction. Confirm access with the relevant local authorities and avoid entering bat roosting areas without appropriate guidance.
Sikkim: The Four Great Holy Caves
Sikkim's Four Great Holy Caves, or Phug Chen Zhi, are sacred Buddhist sites associated with Guru Padmasambhava. Their traditional directions are described in relation to Tashiding, rather than the state's modern administrative districts.
| Direction from Tashiding | Cave name used by Sikkim Government |
|---|---|
| East | Sharchog Beyphug |
| South | Lho Kando Sangphug |
| West | Nub Dechenphug |
| North | Jhang Lhari Nyingphug |
Spellings vary in transliteration. These are pilgrimage destinations with distinct approaches and local customs; they are not four entrances to a single underground cave system.
Cave Lengths: How to Read “Longest” Claims
A cave survey measures mapped passages. Further exploration or a newly established connection can change the recorded length. Total passage length, vertical depth, straight-line extent and visitor-route length are different measurements.
| Cave | Published description | How to interpret it |
|---|---|---|
| Krem Liat Prah | Over 34 km; described as South Asia's longest natural cave | Attribute the claim to the source. A definitive current ranking requires the latest comparable survey records. |
| Krem Puri | Over 24.5 km; described as the world's longest sandstone cave | A sandstone-category record, not a claim to be the world's longest cave overall. |
Neither figure describes a public walking route. For exam answers, use the specified source or syllabus where a question depends on a particular survey year.
Why These Caves Matter
Geological records: Cave passages reveal how water interacts with rock, while mineral deposits can preserve information about earlier environments. Mawmluh is a particularly important example of the relationship between caves and climate research.
Biological habitats: Bats and other cave-associated organisms depend on conditions that can be altered by disturbance, pollution or changes in water flow. Silachari shows why even a cave outside a major tourist circuit can have conservation significance.
Human history and living culture: Khangkhui's archaeological evidence, Mizoram's oral traditions, Jogighopa's rock-cut chambers and Sikkim's pilgrimage caves represent different relationships between people and underground spaces.
Good cave conservation includes leaving formations and artefacts in place, preventing litter and water contamination, avoiding disturbance to wildlife and respecting community custodianship. The surrounding catchment matters too, because water entering a cave may originate beyond the entrance area.

Planning a Cave Visit in Northeast India
Choose the experience before choosing the route. A managed visitor cave, a guided exploration trip, a sacred site and an archaeological location involve different preparations.
- For an introduction: Mawsmai and Arwah have established visitor sections, subject to current local access conditions.
- For exploration: Arrange an experienced cave guide, appropriate equipment and an agreed route for complex systems such as Krem Puri or Krem Liat Prah.
- For sacred sites: Follow the custodians' rules on entry, conduct and photography.
- For wildlife and heritage sites: Confirm whether entry is permitted and avoid disturbing roosts, deposits or remains.
Drier months are generally more suitable for many Meghalaya cave visits, but no calendar month guarantees safe conditions. Rain in a cave's catchment can change underground water levels. Confirm local weather, access, road conditions and any applicable travel permissions shortly before departure.
For undeveloped caves, do not enter alone or rely on a phone torch as the only light source. Follow the guide's equipment requirements and never enter flooded passages or attempt cave diving without specialist training.
