Blah blah hostel and lost hostel are good options. I have stayed there. there are couple of hotels on cliffs might be little costly. lost hostel and blah blah hostel is just near by cliff. u just have to take a turn.
Would you prefer hostels or a proper resort by the beach side.
Varkala has both these options
I stayed at a resort by the beach and it was a decent one.

Depending upon your budget the camera may vary
If you have budget around 25 then canon 1300d with 18-55 mm lens is a great option. If your budget is more than you can go for either nikon d3400 with 18-55mm lens or 18-55 and 70-300 lens
What is your budget if you are looking for budget trip than you should book a budget flight in MMT Things to do in Hongkong and Macau you can accordingly choose you package online or either in airport. I suggest you can get excellent package in airport in good prize.
