We are two thirty-something females who will be spending a week in Trinidad and Tobago in early April. We will be in Tobago for the middle of the trip, and will only have two full days - a Sunday and a Friday - to visit Trinidad. As we have been warned against public transportation and in some cases, taxis, I was wondering if anyone knows of any reasonably priced day tours/bus tours of Trinidad offered, perhaps through a hotel or local visitor center? We are interested in learning about the history and culture of the islands, and perhaps visiting pitch lake (is it worth it?) or one of the nature preserves. Can anyone recommend a safe way for two females to visit Trinidad in two days and get the most out of it? I expect we will get all of our scenic hiking and beach relaxing done on Tobago and we'll have a car rental there. It's Trinidad I am having a harder time trying to figure out. Any advice would be appreciated.
