Firstly, sorry, I’m commenting as a person who doesn’t have ADHD (that I know of). But I always feel a certain way when people in general say, that there’s nothing to do. Now, I don’t know in which capacity ADHD affects you in creating or finding things to do. But I feel like, there could always be something to do.

Here are a few examples:

• make a wreath out of flowers
• practice your handstand
• guess cloud shapes
• take a plunge in the lake
• let flower petals float on the lake
• built one of those stone towers that hikers always do

Or honestly, hiking back sounds like a good idea. Half an hour is an acceptable amount of time to stay at the peak/ any resting spot.
