Masbait Hill (Kelanit hill) overlooks Langgur-Tual and there are sweeping views of the Northeast part of the island and a distant view of Kei Besar.  This isn’t an unmissable attraction but it is very close to other attractions so you might as well stop by for a look:

The trail is well groomed and actually has a quite gentle slope:

This is also a Christian site so there are stations of the cross on the way up as well as a Christ monument at the end:

Practicalities:

Masbait Hill is located about 1.5 kilometers North of the main road between Pasir Panjang and Langgur-Tual next to the village of Kelanit.  Unfortunately, there are no signs so it may be necessary to ask for directions.  Here are a couple of Google images that hopefully help you out a bit (also use the map page)

The walk up only takes about 10 minutes after you find the starting point!
