Sri Lanka, Thailand, Indonesia, Vietnam, Cambodia, Laos, Malaysia, Oman are some cheap countries to travel from india, it’s the south east asia actually.
You should book your air tickets early so you get hands on the cheapest ones, Try to couch surf or stay in hostels to save money on accommodations.
I think that’s all, Hope it’ll be helpful for you.
