Pronunciation: [ʌnklˈa͡ɪməbə͡l] (IPA) 
When faced with a challenge, we may think that it's unclimbable. However, there are several words that we can use instead of unclimbable to describe that obstacle. One synonym is insurmountable, meaning that it cannot be overcome or surpassed. Another word is impassable, suggesting that the barrier cannot be passed through or traveled across. Similarly, impregnable means the obstacle is unassailable or impervious to attack. Inaccessible, on the other hand, implies that the object is difficult or impossible to approach. Finally, we can use the word formidable to describe something that is intimidating or overwhelming. Regardless of the term used, the message is clear - the obstacle is not easily overcome.
