This guide will tell you how to unlock the "˜Mountaineer' achievement or trophy in Time Flies for reaching the peak of the tallest mountain.
This is a late-game trophy / achievement that is easy to obtain during the fourth stage / bucket list 4.
How to unlock the achievement or trophy
For this achievement / trophy we need to be on stage 4, the house with a ground floor as well as a first floor and basement. The location we're headed is downstairs.
We start off on the ground floor. You want to continue right past the doormat and through the doorway to the right:

When downstairs you'll see this vase with a fly in. Ignore that and head left:

You'll reach this room with a moving toy car set. Fly over the cars and head towards the ceiling:

Once you're past, you'll reach this mountain with a model of the Great Wall of China running through it. Simply land on the top of the mountain:
After reaching the top of the mountain, your fly will plant a flag and you have achieved your objective. Congratulations on unlocking your achievement or trophy!
