At the working tea factory, about 3km above Port Glaud, free 20-minute tours take you through the tea-making process. It's best to visit before noon, when you can see the whole process from drying to packing. There's also a gift shop where you can sample and purchase the fragrant SeyTé and citronnelle. There are fine west-coast views from the car park and you can watch the spectacular white-tailed tropicbirds take flight from here.
