I just went to kenting at the end of august - it was a great time!
At night, they have sort of a night-market-type thing…you can just walk along the street (there is one main street!) and browse and check-out all the souvenirs they have.
You can also rent bikes - they have them available right in the Frog Rock park entrance. (they even have electric bikes - so if you don’t want to peddle, you can “turn on the power” and let the engine do it for you!) cute! So, when I went, we rented bikes and rode to Eluanbi (and stopped along the way to take a dip in the ocean!)
Many places have “packages” of water activities that you can sign up for (snorkelling, jet skiing, etc.)
THere is alot for you to do there - I"m sure your hotel will give you lots of info on places/activities that you can do. Don’t worry!
