The local buses are pretty good ! Depends where you are staying :))

Confermo. In 1 max. 2 ore si visita attentamente tutta.

Had the same issue too. Went on Tuesday only to find that it was closed

We took the trail head at the end of the main road out of Perissa. You can start by walking along the main road on the beach towards the mountain. The road will curve left and you will walk up the hill a ways. There will be signs on your right directing you to the trail head

It’s about half hour walk on a long winding gradual climb up We got the bus which we really didn’t enjoy as the driver swung it round the bends- but hair raising so we walked back down and then went to the little chapel which over looks kalmari ( not always good underfoot) and then walked back down to Kalmari

It was completely fine late morning/early afternoon, although sun was burning, it was refreshing by the wind

It is a long long way up. If you like walking "up" for about 45 minutes it is fine. Otherwise, I would suggest that you try to hitch-hike a car to the top parking lot (if you don't rent a car). Nevertheless, once on the top, the view is beautiful. Enjoy your trip

Another place I won't visit then

I'm not sure of the opening time. However I recommend that you ascend in the morning as it is fairly strenuous climb, and doing it in the heat is not good. Obviously, have suitable footwear and take water. It is worth the effort.
