Did a tour with a guide. Walked around in the nature surrounding the waterfall and went for a swim in the waterfall. When you get all close the current is unbelievably strong and the wind and the water is coming from every direction. Absolutely amazing!
Ask a tour guide to take you to the view point. It should only cost 4-5 cedies more and there is a nice vie of the falls from there. Overall the falls are beautiful. It is better to go visit when it is dry/ Hamatan season because the area is shaded and can get chilly from the mist.
I traveld to Ghana last year with Travels To Africa Tour Operator (www.travelstoafrica.com). My second favourite place (after Mole) was Wli Waterfalls. After a one-hour walking in the forest we reached the waterfall. It was wonderful. I felt calm and peace. No stress only the nature. It's worth to visit it.
a challenging hike to the upper waterfalls - but when you did it, its the best feeling EVER! Do it! Its totally worth it!!! Enjoy the nature!
