We drove to St. Lucia and booked with Heritage based on recommendations! The boat used on the river tour was much smaller than what I saw of a competitor. I saw that as a benefit so you have a smaller group of people on board. The guide was knowledgeable and we saw lots of hippos, a few crocodiles, a few bull sharks, and many different bird species. It's worth a visit if you have some time to explore St. Lucia from any game lodge in the area! It is great to have a car, as the cost to do this on your own is much less expensive if you arrange it on your own.
