Take road 1 up to Mosfellsbær. Turn into road 36 to Þingvellir. From there take road 365 to Laugarvatn and in addition take road 37 in the direction to the Geysir. About 2-3 kilometres after you crossed road 355 you will reach a large summer house area on the left side. Take the first road into this area and drive straight ahead. Just follow this way since you reach a bigger path with two tracks. Turn left since you reach the end of this road. There you can park your car and follow the little foot path right over the first bridge and further till you reach the waterfall.
Downstream from Miðfoss there is another small blue waterfall called Hlauptungufoss.
