Titou Gorge is a deep river gorge at the beginning of the Boiling Lake hike and only accessible by swimming. At the end is a small waterfall.
Best in the late afternoon - the crowds from the cruise ship may have left the gorge and the sunlight is shinning to the entrance of the gorge. Very early morning it is not crowded but it is not the best time of the day, the gorge is in shadow. It is very popular so if a cruise ship has docked in Roseau harbour it might be crowded the whole day same at weekends.
The dry season last from Dec. until April/May. This is also the peak tourist season. Anyway this is one of the wettest regions in the world with 7 liters of rain each year. The climate is humid tropical. The driest month is March and the wettest is August.
