Letters from Gladys are geography-themed standalone crosswords. Each puzzle has five thematic answers, which are places, sights or landmarks in or around a certain location (in this case, a chain of mountains). Each thematic answer is notable enough to have its own article in the English Wikipedia, although not necessarily under the same name that is used here. The goal is to fill the grid, identify the thematic answers and guess the name of Gladys’s destination, which is not indicated in the grid.
Dear Puzzling,
I have once again visited several tropical islands, but it’s by no means an ordinary sun-and-sea vacation this time. I have specifically taken an interest in volcanoes. The ones I have seen on this trip tend to dominate the landscape and offer some rather contrasting environments compared to the surrounding areas. Apparently they are also in a pretty unusual formation, geologically speaking. Can you guess where I am?
Wish you were here!
Love, Gladys.
