is it advisable to visit Guilin in June?

It is acceptable, but it is not the best time. It will be hot and humid in June in that city.
If time is possible, it is suggested to go in March to April or in August.

great but had to be there any helpful tips? thanks

Going there in June, you are recommended to take along some summer clothes, sunglasses, sun cream and simple rainy gear. Before leaving, check the weather forecast again.

If you are going to travel there, it is best to book a hotel in advance to ensure a smooth trip. Once getting there, Yangshuo is also worth ur time. If time permits, you are suggested to experience the Li River cruise!
