When I lived in the north of England, hiking usually meant going for a (long) walk in the hills complete with rucksack containing a packed lunch. Serious hikers would also carry a tent and probably cooking equipment for an overnight hike. When combined with an extended thumb, it was known as hitch-hiking. Going for a walk meant heading off for a ramble but without any encumbrances except for a walking stick for those who needed it. Lunch would be had in a pub or café. Could also mean going for a walk around the block.
For others, like me, that might still be confused on using magst vs gern, the Present Tense 1 notes go into the difference. Use the verb mögen to express that you like a noun and use the adverb gern to express liking doing something (a verb) such as in this exercise with hiking. The notes indicate that mögen can't be used to express liking a verb. https://www.duolingo.com/skill/de/Verbs%3A-Present-1/tips-and-notes

I think you misunderstood what DL indicated: Please read the following that I have copied and pasted from your own reference: The similar verb möchten can be followed by a verb, but Ich möchte Fußball spielen translates as "I would like to play soccer", not "I like playing soccer".)
Actually, it doesn't. Wandern means: to wander, to roam; to move, to travel, to shift; to migrate; to hike, to ramble; to go. In the US, Britain and maybe elsewhere walk might also insinuate rambling and hiking and walking etc, but if we're talking about the TRANSLATION of this particular word, then that is it. Interpretation in other languages may be what it is but.....boogaloo.
When I got the answer wrong, the suggested answer was "Do you like to tramp" which I see is technically a synonym for hike, but honestly I'm a native English speaker and I've never heard it used like that.
I've only ever heard it used as a noun to mean a homeless person or, if you want to get sexist, as an old fashioned word for slut. I'd use tromp instead.
Perhaps it is your regional speech or reading experience! I am British and have seen 'tramp' ( to travel on foot ), in written form; heard it spoken and said it myself.
I believe Tramp, ( as in he is a Tramp ), comes from the idea that the person in question is itinerate in nature (or work), travelling from place to place; often on foot.
Of course I am not an expert on language but, Tramp may have ecclesiastical origins, from itinerate priests wandering by foot from place to place.
My experience of 'tromp' is in the 3rd person i.e., ''S/He tromped off.'', Or, to walk heavily i.e., ''Joe tromped across the room, sounding like a heard of elephants.'' (Apologies to any elephants who may read this! !-p ).
