A serene waterfall just outside of the city that's accessible by a short drive followed by a short hike. Due to the water coming from the mountains and the thick forest canopy, the waterfall and pool is relatively cool.
A beautiful black stone cathedral, built in the Gothic style.
A small but excellent museum on Dominica's natural history and ancient history. Exhibits include pre-Columbian artifacts as well as local art from different eras.
Just east of downtown, the garden boasts landscaped green fields and many labelled tropical trees. There is a hike from the botanical garden up the hill to the east, which offers a wonderful view of Roseau and the Caribbean Sea. The hike is of easy-to-moderate difficulty and will take a novice hiker perhaps 40 minutes one-way. The hike allows for up-close exploration of many native Caribbean plants, many of which are common house plants outside of the tropics. A small shrine is located at the top of the hill, near a look out.
