I do get that when there are too many people the experience is different. I do get that being in the wilderness with, like, earbuds in your ears is different than listening to the sounds of nature. I do get that being off trail can be different than on a trail. I do get that navigating with a map and compass can be different and fun versus using a GPS app on your phone.
But I wouldn't say, "to really experience the wilderness you have to....".
Instead I would repeat the maxim, "Hike Your Own Hike".
