The northern lights are an amazing part of Iceland, the best way to experience them is privately. 
 
To see northern lights, three conditions have to be favorable. Darkness, clear sky (or partly clear) and solar activity. Only book this tour after contacting me first, I will not go out unless I believe there is a good chance we will find northern lights.
 
Our best tour would be just us under a starry sky on a still winter night, gazing at the green ribbon across the sky.
