I have to agree that no, outdoor rides are not boring. But, I suppose it depends on where you live, your options, and what you’re seeking.
To echo the other comments, whether on the road or the trail, getting outside for me is invigorating, whether in the hot summer sun or bundled against rain or hail or snow. Enjoying the scenery, clearing the mind, or focusing and thinking about something, all of it is possible.
Clearly you’re enjoying and needing the social side. Maybe check (again?) for local riders to get out with, recruit a friend to try it, etc. Or, perhaps you need to find a new outdoor route to explore. Or just stick with what works for you.
I typically ride solo, though not always by design. It’s a matter of schedule, fitness, and focus. I’ve gotten used to it and rather enjoy it, though at times there are moments of boredom. But, there’s also the opportunity to meet someone out on the ride and share the ride even if just for a segment, an hour, or whatever. (And most often I never see them again…)
(Sometimes you don’t need human interaction to make a ride interesting. From a solo road ride near the end of a long climb. I heard the bells around the corner as I was riding up a long hill. They came moseying down and there wasn’t a human in sight. )
