All tourists embarking on a journey to witness any Sri Lankan waterfall, particularly those located in the mountainous regions of the island, must be weary of leeches. Make sure you wear sneakers or hiking boots with socks or tight-fitting leggings to ensure that the creepy crawlies do not have access to bare skin on your legs. Although leeches are hardly neither dangerous nor poisonous, they can be an irritating part of enjoying the outdoors in Sri Lanka's hill country. If one is bitten by a leech, it is best to use a card or a similarly flat object to slide underneath the worm and remove it gently. Do not attempt to pluck it off the skin rashly as it will leave behind its teeth and mouth on the skin.
