If you're hiking directly to the Krafla area from Mývatn’s northern edge at Reykjahlíð, you’ll pass the prominent 771m-high rhyolite mountain Hlíðarfjall just before the halfway mark. Around 5km from Reykjahlíð, the mount can also be enjoyed as a pleasant day hike from the village, affording spectacular views over the lake on one side and the Krafla lava fields on the other.
