Varmahlid is not really on the Kjöllur route any more (it is the first place to buy food after the Kjöllur), it is not either a place you would normally mention, as it is a tiny village with a Gas station / food shop, Tourist info, Campsite and obligatory swimmingpool.
For Shoam Varmahlid was a highlight of the trip, for on the campsite she met Cathalena. Cathalena is a german girl, who travelled with her parents through Iceland. Having walked for 4 days from Landmannalaugar to Thorsmörk, they explored Iceland now by car.
I don't know, if it was the shared experiances, the love for Icelandhorses or just the company of somebody in the same age, but the 2 where inseperable....
