Waiting for the sun to set and the bats of Mulu to take flight, mother nature treated us to this wonderful rainbow as a shower drifted across the hills.
The trail we were following to get to our bat flight viewing experience ran close to the cliff edge in places as you can see in the photo below, of a longboat heading downriver.
From high on a hillside we had a great view down onto the river and the new arrivals coming upstream. This photo was taken in the Gunung Mulu National Park in 1989.
This is the same boat and same guides that brought me to Mulu from Long Terawan (and that would return me to Long Terawan two days later for my return trip.
To the right you can see examples of the limestone cliffs that feature in this area. Up in the hills in the top left corner you can see a collapsed surface. These highlight some of the challenges of hiking in this area. The terrain makes it extremely difficult but you could be hiking along and find yourself on the edge of a cliff. Being so far from help, that's why you stay on the trails.
I took this photo from the banks of the Melinau River in the Gunung Mulu National Park in Sarawak, back in 1989.
