There is no law per section to forbid you from trekking up on the glacier by yourself. HOWEVER much local knowledge and common sense suggests this is not a good idea. PLUS SIDE, DOING IT YOURSELF...anyone can hike safely from parking lot to great views, gdecent conditions. You may find yourself content with this. If you want on glacier experience, there are guiding services at parking lot...or you can pre book. The point is, please dont attempt on your own. Here are my pictures, no guides needed, from trail to view glacier

Hello, you need a car for everything in Iceland. A normal car is okay for this street and parking place.

The best camping would depend on the time of year and the amount of daylight available. I would go with a professional guide. Quicksand is common near the glacier and at times there are falling stones.

Take the 221. It is asphalt so no need for a 4wd. I used Google maps to get there. Enjoy.

Yes, you can definitely access it even if you don't have a 4wd. It is super easy. You park by a small building/barrack and walk as far as the trail allows you. You need to stop at the point which informs you it is no longer safe to walk (unless you are with someone qualified or a tour).

We walked alone, but did not do the whole glacier as we had four children below 16 in the group. We walked till the mouth of the glacier and about 200 meters up,

Det er jeg ikke sikker på. Er en ganske storparkeringsplass der, men den er grus og stein så tror egentlig ikke det

No, I think you can only access it by car or arranged transportation.

Definitely well worth the stop. Allow yourself at least 45 min. - 1 hr. for the walk up to the foot of the glacier as the walk is nice. You don't need a guide for that portion.
