Middleham Falls is one of the tallest waterfalls on Dominica. The trail entrance to Middleham Falls is in Laudat and has a well-marked sign that makes it easy to find. I recommend picking up a copy of Bradt’s Travel Guide of Dominica by Paul Crask, this is a fantastic guide with clear directions and tips.
The Middleham Falls hike takes about an hour each way, has a well-maintained path with steps and bridges, and is an enjoyable hike through the rainforest. I saw an Agouti (looks like a Guinea Pig) for the first time, some of the larges Chataignier Trees I’ve ever seen, and had a chance to break my FiveFinger hiking shoes in on this trail. I would highly recommend this experience to anyone visiting Dominica.
