Whenever I teach English idioms, this can be one of the tougher idioms to walk through, no pun intended.
What does “hike” mean to you? A hike can be a long walk, a long period of travel, or with regards to money, money and prices can hike, they can go up.
On the base level, we know to take a hike means to take a nice walk, a tough, challenging walk in nature.
However, the idiom goes to another level. When we tell someone to take a hike, or someone else tells us to take a hike, it means to leave in a negative way. Leave, good-bye.
Hopefully that hike will be a better to a better place.
