Not a jungle of hidden shrines
The Western Ghats are a long range of hills running down India’s western side, with forested slopes and heavy monsoon rains. The idea of a jungle full of mysterious temples makes for a vivid image, but it is not what makes the range important for Buddhism. What is well documented is a series of rock-cut Buddhist cave monasteries in the northern part of the range, in Maharashtra. They were cut into the hills along old trade routes that linked the coast with the interior. The better-known sites of Ajanta and Ellora lie further inland; this article concentrates on the western group.
Why caves in the Ghats
Many of the caves are close to ancient passes that merchants used to carry goods between coastal ports and inland markets. Buddhist monastic communities were often supported by traders, officials and rulers, and caves offered a durable, cool and quiet space for monks, particularly during the rainy season retreat. The surviving inscriptions in some caves record donations by laypeople, though specifics vary from site to site.
Bhaja
Bhaja, near Lonavala in the Pune area, is generally regarded as one of the earlier sites, often dated to roughly the second century BCE, though dates are debated. It has a prayer hall with an apsidal plan and a row of monastic cells, along with a group of small stupas cut in the rock. Its simple style, imitating wooden construction in stone, is helpful for understanding how this architecture evolved. Visitors are taken by the setting, which looks over the hills.
Karla
Karla (also spelled Karli), not far from Bhaja, is celebrated for its large prayer hall, often regarded as the finest and best-preserved early example of its kind. It has a high vaulted ceiling, rows of pillars and a stupa at the far end. The hall is typically dated to around the first century BCE to the first century CE, with scholars differing. A Hindu shrine on the site continues to draw worshippers, so the place remains in some religious use.
Kanheri
Kanheri lies inside a national park in the northern part of Mumbai. Its cluster of well over a hundred caves, cut into a basalt hillside, was occupied over many centuries, which makes it unlike the earlier sites. There are cisterns, stupas, a large prayer hall and cells. Kanheri shows how a monastic centre could grow over time near a major port. Because it is within a park, entry rules, hours and transport arrangements follow park regulations.
Other caves
Further caves exist in the region, including sites in the Pune and Nashik areas, and various less visited groups. Information about some is limited, and access can be difficult. Do not assume that a site is open or easy to reach.
Reading the architecture
These caves are a good place to learn the basic vocabulary of rock-cut caves. Prayer halls, known as chaitya halls, are built around a stupa. Residential halls, known as viharas, are arranged around cells. Knowing the difference between a chaitya and vihara, and the parts of a stupa, helps when you stand in front of one carved from living rock.
Visiting safely and respectfully
The Western Ghats are especially affected by the monsoon, when steps may be slippery, streams swell and landslides can occur. Check weather and official advice before heading out. Treat the caves as heritage and religious places: dress modestly, remove shoes where requested, avoid touching carvings, and follow local rules about photography. Because some sites have wildlife around them, stay on marked paths and follow park guidance. This is general information only; confirm opening times, fees and access with official sources.
