You can go there on your own or book a tour (both in Sapa and Hanoi). The fields look amazing all year round, during harvest and even winter when they are covered in snow.
A unique and relatively easy circular path, a must visit if you are in eastern Crete.
Stunning surroundings from beginning to end no matter which way you take (down the gorge until sea level and then up the farm road or vice versa).
You can also "cheat" by driving to the beach and walking to the waterfall from there (about 1h) but keep in mind that the road is twisty with no protective barriers.
Highlight of our vacation last year, will visit again on next occasion.
