Answer:
In the book "The Lion, The Witch and The Wardrobe" by C.S. Lewis, the first place the children decided to go after arriving in Narnia was to explore their surroundings and find out where they were. They had just stumbled into the magical world of Narnia through a wardrobe in an old house where they were staying during World War II.
After wandering through the snow-covered forest, they came across a lamppost in the middle of nowhere, which was very unusual. They soon met a friendly faun named Mr. Tumnus, who invited them to his home for tea. It was during this visit that they learned about the White Witch and her tyrannical rule over Narnia.
So, while the children did not have a specific destination in mind when they first arrived in Narnia, their exploration led them to the lamppost and eventually to Mr. Tumnus' home.
