I want to go to Hukou Waterfall. I have to sit behind a motorcycle from Xi’an, and I can’t take the high speed. Can any friend recommend a route, and I can walk along Huanggong

Outgoing journey: Xi'an--Yanliang--Pucheng--Baishui--Huanglong--Yichuan--Hukou--Return along the Yellow Highway--Hukou--Hancheng--Heyang--Dali-- Weinan - Xi'an
