Talakaveri, the source of the river Kaveri located in the Brahmagiri hill near Bhagamandala in Coorg district, Karnataka, is best visited during the post-monsoon and winter months starting from October to March. During this period, the weather in Coorg is pleasantly cool and is most suited for sightseeing, trekking, and enjoying the natural beauty. The monsoons, from June to September, bring heavy rains that can cause a lush landscape; however, it makes it difficult to navigate the hilly terrain and might lead to the closure of paths due to landslides or flooding.
If you are interested in witnessing a unique cultural event, you might want to plan your visit during the Tula Sankramana, which usually falls in the month of October. This is when the spring at Talakaveri is believed to gush forth at a predetermined moment. However, if you're looking to enjoy the serene atmosphere devoid of crowds, consider visiting during the weekday mornings between November and February, when the climate is cool and the tourist influx is lower. Always remember to carry warm clothing during this time as the temperatures might dip, especially in the early mornings and evenings.
