I have lived in West Africa for two years and can confirm that there are people diving there. As far as I know the numbers are limited and mainly local expats. Also the Club Med in Assinie (Ivory Coast) has no diving in its offered activities. Benin is accorcording to my knowledge no favorite dive location for Dutch tourists. I can however recommend visiting Cotonou / Benin as it will show you a completely different culture compared to Europe and in general the Benin people are quite friendly
