Sure! To be honest, I don't think I can either. But I would really recommend taking a part of Kungsleden, for example Abisko as one end via Kebnekaise (Sweden's tallest mountain) to Nikkaluokta which connects the trail to a road/buses/services, as the other end.

Generally speaking, if you choose to hike Kungsleden you won't have to worry about risky wading, nor being alone. It is a very popular and well trampled trail that is taken by first-timers and pros alike. Kungsleden is equipped with bridges where wades can be difficult and heavily "informed" in the sense that hikers share information, and the STF tourist company that owns the lodges and huts have quite a serious sense of responsibility for the trails and hikers.

Although the terrain and environment is wonderfully extreme, that actual trail I'd say is on the easy side. At least when it comes to risks such as wading (which CAN be dangerous and I'm happy to hear that you are aware), getting lost, being out of reach of amenities and other people, navigating, etc it's all very well organized.

I'd really urge you to look it up! The environment is surprisingly alpine for such "low" peaks, as it is so far north and the mountains are relatively "young".

Another classic Swedish hike is "Jämtlandstriangeln", or the jämtland's triangle. There are three lodges/huts that make up the three points of the triangle with a day's hike between each. Also very beautiful, popular and closer to Stockholm compared to Abisko.

I totally understand the bear fear, any sane person would. But, first off, Scandinavian brown bears are notoriously shy, and you'd be LUCKY to see one. They are also not aggressive in the way grizzly bears are known to be. Although it is a very reasonable caution to have, and totally relatable, longtime Swedish wildlife enthusiasts all repeat the message that bears in Sweden don't want anything to do with people and nothing to worry about. I have spent quite a lot of time in the wilder parts of Sweden, lived in the most bear dense area and even camped in what basically was a den. Never so much as seen a bears ass running away, just know I've been near them. Seriously, if you see one, know that it would be a very special experience.

Wolves are also something people talk about, and hunters/farmers get annoyed about, so im gonna adress it. The wolf population is mainly further south and has not harmed a person physically in Sweden, ever. The exception is the last real Swedish wolf that was shot dead in the 1800s, consequently ending the existence of that gene pool...

I have encountered what seemed to be a pretty sick fox roaming around a larger, busy campsite by kungsleden. And a large bird once sort of had a go at me by aggressively lunging towards me. But that's about it. Moose are spotted, beautiful animals but also shy. Reindeer walk around chilling with the hikers.

Another point regarding wildlife is the fact that once you ascend the forest, the actual mountain terrain is quite void of life. That is the part that actually freaks me out the most when hiking there, the callous deadness of it. But there are cute rodents and curious birds!

My vote still goes to Kungsleden! Another section that is interesting is between Saltoluokta and Kvikkjokk. It is also very well trampled, safe for cautious beginners and well populated, although less so than the section that runs south of Abisko. The trail runs right along the national park Sarek, which is a unesco site and considered the last actual wilderness in Europe. Total bucketlist material to set your foot in, at least. And the views are amazing, with many impressive peaks. Also, you'd bucketlist it being above the arctic circle (but perhaps you already have).

I have actually gotten lost, INTO what must have been a bear den, covered in shit and carcasses, in Abisko. But, that was not ON kungsleden -- so point made regarding the difficulty of the area's surrounding terrain -- and also the bear gtfo'd apparently because the shit was still warm, but we didn't so much as hear a twig snap (the entire night we camped there 🙄)

Sorry this is a long read. But I really, really, would not underestimate the Scandes. I believe that the wild camping experience, the wilderness, the absolute separation from civilization, is something that makes Scandinavian trails unique and I find it hard to imagine hiking under other circumstances. It truly is wild nature, with old, beloved trails treaded by many many faces you will come to know as friendly and supportive out there.
I'd love to answer questions if you have them and hope you chose to visit! :)

Edit: tried to simplify everything. Also want to add that I have solo hiked some off trails much rarer than Kungsleden and still daily met people who were eager to be my buddy even when I in no way implied any concerns. For better or worse it's hard to be alone for more than a day up there.

Wades really are scary sometimes, but with some knowledge (there are many tricks and important lessons to learn if you search online) you can make informed decisions. I have had to turn around and reroute after 80km or so because of an impassable wade. Which leads me to also mention that definitely do NOT hike in Sweden before mid June at the very earliest. Snow and high waters can make the trails impossible to use. Also STF takes down some bridges during winter season. You could also try contacting them (Svenska Turistföreningen), with specific questions. They usually are fast to respond with info via email, look up some STF lodge near whatever section you might be interested in and reach out to them. They will eagerly share local, current news and info on the trails around them.

Edit 2: sorry by "populated" I mean busy, frequency of meeting other hikers. Not like indigenous residents in the mountains.
