South Iceland

I'm planning a trip to South Iceland. This started out as a trip to do the ring road loop of the full island but that began to look like far too much driving when I can only get away for about a week. So instead I'm focussing on the glaciers and landscapes of the south, from the airport across to Höfn.

We've both been to Iceland before, so we're skipping Reykjavik and the golden circle sights. Below is my plan so far, and I wonder if anyone who's travelled this area before has any suggestions for any things I've missed? Personally I'd like to explore more of the glaciers such as getting into ice caves, but my partner is less happy on the ice, so we were thinking the snowmobile trip below may be a good compromise. The tour companies' descriptions are a little vague on how difficult the trips are.

Seems like you're hitting all the high points for South Iceland

I've heard good things about Múlagljúfur Canyon but we didn't try it. The turn off from the Ring Road is notoriously hard to find and there are drop offs. Fjaðrárgljúfur is pretty but it's a paved walkway, not a hike. Don't miss Diamond Beach and the seals on the opposite side of the Ring Road from Jökulsárlón.

At Seljalandsfoss don't miss the nearby hidden waterfall Gljúfrabúi. Budget plenty of time at Skogafoss to climb the staircase and walk the beginning of the Fimmvörduháls trail.

There's a really beautiful little gorge with a hiking trail I found that's not in any of the guidebooks. It's on a little side road off the Ring Road near Skogafoss. I don't know if it has a name but there will be a "gongulei" sign marking the beginning of the trail.

Thanks very much, I'll check all of those out.
