Holi is a big time festival and not just in India. I am not sure if there is any place without even a bit of craze for Holi. If you get to find a place, do let me know.
You should then be visiting the hilly ranges of Kerala. Idukki, Munnar, Vagamon, and nearby places would surely give you peace of mind. You can also expect early monsoon rains if your'e lucky.!
Hi dear, There is lots of place at south side. my sister is also doing job and no celebration of diwali and holi ... like you can go at shimoga, kanayakumari, nearest Bangalore villages. happy travelling! :)
