It will be disappointing to some and it was even for me. Years ago in the 80s, Lombong Falls is a place of unspoilt beauty. Natural rocks with rock pools. Fishes that come pecking at your feet as you cool them sitting at the river's edge.
Now, there are man-made slides. A dam that artificially creates a "swimming pool" area. Sadly, I would have to say that much of the natural beauty is lost in an effort to attract more visitors.
Unique Suggestions: Just go and have a swim or a dip. They spoilt it but that doesn't mean you can't enjoy it.
Carefully choose the right resort that provide activities and facilities that suit you. As Desaru itself has very less of things you can do and see, so your holiday will very much depend on the resort. Don't turn your holiday end up with a unpleasant trip like coming to a big tourist trap place.
