There are many unpaved paths, but since there is not much difference in elevation, it is no problems to wear sneakers on sunny days.
On rainy days, there will be many paddles and wet mud, so it may be better to wear waterproof shoes such as trekking shoes.
If wearing sneakers, it is a good idea to use a waterproof spray.
It is basic to use bags that will allow both your hands to be empty.
If you are hiking/walking for a long time, it will help you from getting tired by having the weight close to the center of your body. Adjust the length of the straps on your backpacks so that they are not too long, and it is comfortable when you carry it.
We do not recommend you to use bags with casters. The casters may break by using them on unpaved paths. If necessary, it will be safer to send your bags in advance to the hotel.
