Mate,
I was up there at the begining of April.
Hook Point was open and passable, but a number of fallen trees meant it was only feasible an hour each side of low tide.
On the run up the island we had to take the inland road. Full length from the barge landing to Dili Village is about 18kms. However there are tracks down to the eastern beach at regular intervals.
If you take the inland road make sure everything is well secured as the corrugations will give everything a good shake.
If at all possible avoid the inland road.
Jim.
