We will be staying in Hvolsvollur for 4 days around 20 June and we would like to do a day hike either around Thorsmork or Landmannalaugar. Which would you recommend and is it possible to do a hike in either area without hiring a guide? Would we be able to drive on our own to either area (we are renting an AWD SUV)? I'm pretty sure we can't drive ourselves to Thorsmork, but I'm not sure about Landmannalaugar. I found that hiring a guide or even taking the bus to Thorsmork to be very expensive. If we should do the bus or a guided hike, can you recommend a company or web site? Thanks so much!
