This new update makes the place feel more EPish

Yes, you can hike from start to finish. It's 2193 miles long starting in Main and ending in Georgia. It is an amazing experience, especially if you can get it in one go. You need about 6 months give or take to complete the trail. There are many towns along the trail to stop and re-fresh supplies in. Many people also choose to spend a hotel night here and their while in towns. There's also some really cool festivals along the route if you time it right. It's a tight knit community that completes the AT. Check out YouTube, there's lots of great videos about it on there. Another great starting place is https://appalachiantrail.org/. Of course, most people that spend time on the AT only do so in smaller bouts, because the trail winds through towns it's easy to hop on and off and pick smaller hikes that take less time.

I'm certain there is, just don't know of it. On the west coast there's the Pacific coast trail. Yet it isn't just a coastal trail. It goes through deserts and mountains.

There are hiking trails in the Dolomites!
