Boh Tea Plantation, Cameron Highland, Malaysia. BOH Tea Plantation is a must-visit place when you are in Cameron Highlands Scenic, tranquil & cool fresh air! The road journey to the BOH Tea Plantation is quite an adventure itself. Boh Tea Plantation has a total of 8000 acres planted with tea. The largest tea plantation in Southeast Asia. Road is narrow and winding. Do give a honk or two while negotiating a corner to let oncoming traffic know there is a car coming. Gets kind of fun to honk the horn after a while!
