Il-Qolla l-Bajda is found between Xwejni Bay (Ix-Xwejni) and Qbajjar Bay (IL-Bajja Tal-Qbajjar). Il-Qolla il-Bajda is called the White Hillock as it is formed out of varying light gray clay with a pale yellow sandstone top. This Qolla has the classic Maltese "hill top" shape with a slab of material on its top.
Xwejni Bay and Beach is great place to spend a day. You have restaurants close by and a good beach (for Malta and Gozo) that is not just a sandstone outcrop. The rocky beach is covered with interesting stones, these are multicolored.
The cache can be found at the top.
It's a petling in a column.
You have to climb to get to the top, and the rock is soft and brittle. And you have to come down again too ;-)
Please be careful, it's not worth hurting yourself.
