Hi, Pradeep!
Destinations like Malaysia, Vietnam, Thailand, Bali, Sri Lanka, and Bhutan are some great choices for a honeymoon within the budget of ₹1,00,000. However, there are other factors involved which can alter your budget like the time of the year when you are travelling, whether the flights are booked or not, what kind of experiences you are looking for, and many others.

If you are beach lover thn you can go Mudhdhoo Island (also known as Vaadhoo Island) in Maldives(at night you can enjoy a Bioluminescent Plankton). It will be an amazing experience.
