Tobago Is very beautiful, undeveloped with great beaches, excellent snorkeling . Take a trip to Charlottesville, the government run bus systems works great.
Englishman Bay is also great for snorkeling. There is a big grocery store on the main road in Bon Accord. There is not much to do in the night time. The glass bottom boat is a great to see the reefs, you can go out from Pigeon Point or in Speyside .

In Pigeon point you will find a lot of locals selling food, clothes etc. Buccoo area there is also great local food.

Castara and Englishman bay is great but the road is very hilly and curvy driving is easy if you rent a car.

We've stayed at Turtle beach and the old Hilton on sevearal occassion.
