In this article, we had studied the touristic site of the Kalamu River in Boma, « Bas-Congo » province in DR Congo. The river had known biophysical changes precisely because of human activities directed toward her. Therefore, these activities have had a negative impact on the smooth running of tourism across the river for nearly 54 years that is why it had been ignored and even forgotten by the people.
Our investigations were based on direct observations, the review of reports and documents of the Boma City office, Agency of Boma National Tourist Office and some research that has been done on this site, and discussion with repentantives of the ONT Agency.
The results obtained show that the river was Kalamu a tourist site visited by various categories of people (fishermen, sailors, officers RVM, population, etc.). It was noticed that the river had lost its normal bed and that during heavy rain, it flooding occurred. The pollution observed introduced the risks of eutrophication of water borne diseases, loss of beautiful scenery, etc. The Baobab site Stanley still remained a special place to visit for tourists of all categories. This publication was done to call the conscience for environmental preservation of the touristic site.
