Hi I cannot answer all of your questions but here goes. We had a driver to look after us all the way through so we did not use local bus/ train transport. Although I can tell you that using trains needs to be many weeks in advance, all train lines are single track and they only run a few trains per day, with limited seats for tourists. I would not recommend the train from Kandy to Newark Eliya, its a very very slow, cramped train that has little comfort, especially with young children. You can buy a visa at the airport but I cannot remember how much we paid, we travel as Brits so not sure what it is for Indian citizens. I would recommend a small boutique hotel in Triincomolee called Palmera Eco Resorts, actually up just north 2km in Nilavelli. In Kandy we stayed at the Grand but as per my TripAdvisor comment its old and tired. Kandy is just a mega busy bustling noisy polluted city but worth a short 2 day visit. Obviously even with the recent troubles its still worth going. Good luck and enjoy.

It's depend on u r budget, much better to looking to trip advicer comments.

Yes it’s possible and people would love to help u.thank u!

As this is located in Sri Lanka, you need a valid passport to enter into the country. Indians can obtain Visa on arrival. You have to travel to Trincomalee. You do not need to carry your passport for entering this place, but better to keep it with you for identification purposes.

thank you very much for the detailed answer.

It's best to walk up to the temple on an early morning to experience the full beauty of the surrounding. The uphill part of the walk is short but a bit steep for especially an elderly person. Better to take a tuk tuk which shouldn't cost more than 100 rupees one way and there'll be no added issue of finding parking.

If you could let me know from where you are going to start the journey then I will be able to provide specific instructions on how to go there. But you will not get lost cause it is NOT in an isolated area. Its very famous so anybody will be able to show you or give you directions to go if you are in Trincomalee. If you are going there from Colombo then there are easy and comfortable way to go like hiring a vehicle. if not go by train then go by bus or a taxi. in Sri Lanka there are plenty of Three wheels which they called Tuk Tuks so you can get down from the main bus station/train station and take a one to go to the temple.

Avoid visiting the temple after around 10.00 am until evening because the stretch you have to walk bare foot gets very hot.
