Gabhla is one of the lesser-known islands. Long uninhabited, interest was revived recently, particularly among rock climbers and birdwatchers. An off the beaten track walk brings visitors to a lake with abundant bird life; cormorants, razorbills, guillemots as well as gannets and kittiwakes. Somewhere this peaceful, you may feel as though you've been transported to another world - but the island is in fact only 2km from Gweedore, with ferries departing from Magheragallan (Machaire Gathlan). Note: during low season, booking is required.

This fantastic Roman Catholic cathedral, also known as Madame l'Afrique, can't absolutely be missed in Algiers. The stunning building, completed in the late 19th century, features a grandiose interior and, since 2012, it is listed between the historical monuments in Algeria.

There are two waterfalls in the vicinity of Nha Trang, both of which make for excellent excursions into nature. Ba Ho Falls, at a distance of roughly 30km north of central Nha Trang, are the falls that attract most visitors. You will need a ride to reach the entrance to the natural area (get a taxi or Grab). Bring swimwear, sturdy shoes (not flip-flops), and your own water. Note that water volumes may vary dramatically depending on whether you visit during or outside the dry season (January through August). Another option is Fairy Spring Waterfalls (Suối Tiên), mostly favoured by local youth. These are much smaller compared to Ba Ho, but there is still an opening fit for swimming. There is a small admission fee to visit both falls.
