Deep in the tropical rainforests of Brunei is the Ulu Temburong National Park. It's the first national park in Brunei and is relatively young as it was created in 1991. The vast unspoiled jungle is also known as "The Green Jewel of Brunei."
Looking out at the endless green trees really helps you feel just how remote this place is. I accessed the park by a long, narrow wooden river boat. My guide, navigating the boat on the Temburong river until we reached the base of a path allowing us to hike up to the canopy walkway. There are several other rainforests in the world with canopy walkways, and as long as you're not afraid of heights, the perspective it offers is definitely worth climbing up for.
