here is a non-exhaustive list of things you can do around Diego:
- visit the 3 Bays. Note that the Bay of Diego is the 2nd largest bay in the world.
- Orangéa-Cap Miné , an old colonial fort/base
- Red Tsingy
- Emerald Sea
- Amber Mountain
- Tsingy of Ankarana
- Montagne des Francais
- obviously the town of Diego Suarez- Antsiranana. Plenty of good restaurants there and perfectly safe to walk at night on the main street.
Please make sure you contact a tour operator which have a licence and legal authorization to organize tours. We often see " guides" who promote themselves to organize tours and fool their customers . You have the list of the members of the association of tour operators here:
