Riding local, riding abroad. Doesn't matter. "One less car" bike commuting and "Bikes Belong" advocacy, plus "I ride solo" bicycle travel. Racing is fun, but there are so many equally great reasons to ride.
The bus dropped hikers at various points on the way back to Reykjavik. This is a camping and hut site called Landmannahellir. We forded several streams on the volcanic gravel road, and it was bumpy going both directions. Worth the price of admission as this is a unique place.
The Reykjavik Excursions bus ahead of mine (TREX). I took the 7:45am bus from Reykjavik Campsite and it was a milk run, not arriving until after noon. My Hikers Bus Pass cost ISK 12400, or about $100. Cheaper than RE.
