We are now back in Kuching so here is a little more about our time in Mulu National Park starting with Friday.

We travelled north from Kuching to Mulu an area of limestone mountains covered in pristine rainforest and famous for some remarkable caves including the Deer Cave – the largest cave in the world (spot the people crossing the cave floor in the photo below).

 The park entry is over the river on this rope bridge.

We met up with our fantastic guide, Henry, and headed out into the forest. Of course we walked much more slowly than any other visitors as there was so much to see – plants, orchids, insects and snakes. This wonderful Bonean Pit Viper was in the tree above us.

 The snake is around 4ft long and very venomous – but not aggressive.

The Deer cave is the largest cave in the world (spot the people crossing the cave floor in the photo below) and you will probably have seen David Attenborough there in the past. It has 3million bats – we could see them as dark patches on the roof – an enormous amount of bat guano and the smell to match! It was a real experience to visit.

The far end of the cave leads to an inaccessible jungle sink hole.

We came out of the caves in time to see the bats emerge at dusk to eat their fill of jungle insects while we returned to our hotel in the forest.
