The Laugavegur is one of the big walks. It is the most famous trek in Iceland and crosses other worldly landscapes formed by recent volcanos. I did it from north to south and it runs over 80km from Landmannalauger via Thorsmork to Skogar on the coast. The trail is normally open from late June to mid-August. I started on the 15 June, the first day the bus ran to Landmannalaugar. I hadn't booked the huts as I didn't know whether I'd make it. So I took camping gear. The scenery is sensational and unlike anywhere I'd been before. At this time of the year there is still a lot of snow. I was alone much of the time, having started early in the year. There were three river crossings in flood and I needed to strip and take care. You pass through vivid rhyolite mountains, climb snow slopes, cross ash deserts, rift canyons and glacial streams. There are wild flowers, sweet birch and the cries of redshank and ptarmigan. I did the trek from Landmannalaugar to Skogar in 4 days including the bus trips at either end.
