This is part 58 of the puzzle series Around the World in Many Days. Each part is solvable on its own.
Dear Puzzling,
This is a diagramless checkerboard crossword. Empty cells are either blue or white; one of these cell colours only contains vowels (A, E, I, O, U) and the other only consonants (including Y). Clues are given in alphabetical order by their answer. Solve the clues and fill the grid with the answers. Answers can be anywhere in the grid, are allowed to share letters with other answers, and don’t need to be separable using grid lines. For example, if two of the answers are ABET and GABE, it is allowable to insert them into the grid as GABET, sharing three letters. I hope this makes sense!
Today I have explored rock formations, cave systems and underground rivers in a World Heritage-listed national park. Can you guess where I am?
Love, Gladys.
