Goa Jomblang

We arranged for a driver to take us to Goa Jomblang, a vertical cave in Semanu, about 2 hours by car from Yogyakarta.

Things to know:

• The entrance fee includes lunch after you return from the cave, guides, as well as all the equipment needed to safely get in and out of the cave. Make sure to bring enough cash.
• You need to wear boots to go into the cave, which are supplied, but a little bit smelly. Bring long socks. The helmets are clean and no problem to wear.
• Most importantly, there is a limit of 25 visitors per day.
• Be at the cave no later than 10am.
• It's quite damp and warm in the cave. Bring drinking water.
• This tour involves walking on and climbing across muddy cave floor and steep slopes into and within the cave. We had a lot of fun, but this is not for everyone. 

Arrival and waiting for the tour to begin 

Picking out boots

The cave is basically a giant sinkhole, 50 meters across. The edges and walls are overgrown with dense forest.

Pairs of visitors rappel into the cave from the edge. This is probably the most adrenaline-producing part of the trip...

At the bottom of the cave awaits dense, tropical forest.

The group descends into the connecting cave to make our way through 300 meters of darkness to the main attraction. The guides have lights, and there are some stationary lights in the darkest section.

Luweng Grubug awaits at the end of the tunnel. An opening in the cave ceiling allows light to come into the cave and produce the most heavenly effect.

We spent over an hour here, taking photos, rest, and just enjoy the view.

When it was time to return, it was very nice to see the green forest in Goa Jomblang again.
