I am interested in doing a 2 week driving tour of iceland. I am interested natural wonders, hot springs and day hikes. I would like to avoid the crowds as much as possible but I don't want to be limited by poor road conditions. My ideal weather conditions would be above 60F during the day, as dry as possible with the longest hours of daylight. I plan on renting a 4x4 vehicle. Any suggestions for the best time to visit?
