I enjoy challenging caches. High Terrain Caches.
This cache requires a boat (T5) and a ladder (T5).............and some nerve.
Does that make it a T10?
Well Frullet has proved that a ladder is not essential and I believe you may be able to get there in a 4WD in the dry season so I guess it’s only a T4.5.
It's often true that 4.5’s (as in this case) can be more challenging than T5’s.
Enjoy
Congratulations to Karicka and Frullet for being the FTF.
