On my 4th day in Malta, from Valletta I visited Mdina TWHS and Maltese Catacomb Complexes TWHS and then took the bus 201 from Mdina to the bus stop "Panorama" for Blue Grotto, also stopping at Dingli Cliffs on the way for Malta South West Cliffs TWHS.
I have no idea if Blue Grotto, which is located on the South West coast of Malta, is part of the Malta South West Cliffs TWHS. But it's perhaps one of the more scenic parts of the South West coast of Malta.
From both Dingli Cliffs and Blue Grotto, Fifla Islet, which is one of the 5 components of this nomination, is visible, as you can see above the Blue Grotto in this photo.
When I think about cliffs, I typically remember Cliffs of Moher and equally scary cliffs on the Island of Aran in Ireland (which are not even nominated for WHS), so I was wondering if these cliffs are similar to them, but they weren't. But if I look down from the edge of the cliff on Fifla Islet, I would feel different. At no point of my visit was I able to identify any endangered species.
With the bus 201 you can also visit Megalithic Temples WHS at Ħaġar Qim and Mnajdra, which are only 1 km away from the Blue Grotto.
From "Panorama" I took the bus 74 back to Valletta.
Staying in Malta for 4 nights was hardly enough to see all the main attractions in Malta. I did not even get to go to Gozo. I might opt for coming back to Malta for a 3-month stay, as I am finding that "living" (or staying just for 3 months) in wherever I go is much more intriguing than just "visiting."
