Located near Lihue, Wailua Falls trail is a .3 mile downhill hike through a forest area covered with tree branches, roots and large rocks, that can also be very muddy. Even though I don't have much hiking experience, I managed the trail well. One reason could be that my companion on the trail Patrick, who also took my pictures (www.pk-worldwide.com), is an experienced hiker and was able to guide me through the hike without any difficulty. The trail can be somewhat challenging and I don't really recommend it for people with bad knees or a bad back. At some places the locals have hung ropes to help you climb down (or up).
It took us about 20 minutes to arrive at the spectacular Wailua Falls that I had also seen from my doors-off helicopter tour. However, the falls were a bit crowded for us and we didn't stop there. We kept climbing down for another 10 minutes where there is another waterfall with a natural pool. We spent our evening by this second waterfall and also swam in the pool there. There is also a rope suspended from a tree above the pool to help you jump in the water! The climb up can be rated as moderately difficult but if you have a good guide and no hiking experience (like me!), you can do it! Also, it is important to dress appropriately. I was wearing shorts and comfortable water shoes with a cross body bag so that I could have my hands free. Patrick carried the camera bag, backpack and the rest of the stuff! He has done this trail many times!
