Belum Caves, located in the Kurnool district of Andhra Pradesh, are renowned for being the second-longest cave system in the Indian subcontinent. The ideal time to visit these ancient and fascinating caves is during the months of November to February, when the weather is relatively cool and pleasant. During this period, the harsh temperatures of the region, which can soar during the summer months, subside to a comfortable level, making the exploration of the caves a delightful experience. The natural stalactite and stalagmite formations, along with the intriguing pathways and chambers within the caves, are best enjoyed when the heat is not a deterrent.
In addition to the comfortable weather, the winter months also coincide with several local festivals and events that might add to the cultural richness of your trip. However, it's worth noting that the caves may get a bit more crowded during weekends and public holidays. To ensure a more tranquil visit, you could plan to explore the caves on weekdays. Remember to wear comfortable clothing and shoes, as you'll be doing a lot of walking and navigating through the varied terrains within the caves. Also, carry a good quality torchlight or headlamp to enhance your viewing experience, although the caves are electrically lit at important junctures.
