Can we go to Tongling Grand Canyon and detian Waterfall in one day by myself?

I think it is better to visit these two sites for two days. If you do it in one day, you need to start the trip in the very early morning. You can visit the Detian Waterfall first, normally half day is enough. From Detian to Tongling Grand Canyon, you may check with the scenic spot if there is any shuttle bus available. If not, you can charter a car with other travelers, the fare is around CNY150 and the ride takes about one hour.
