Keldur

About 5km west of Hvolsvöllur, unsurfaced Rte 264 winds about 8km north along the Rangárvellir valley to the medieval turf-roofed farm at Keldur (thjodminjasafn.is; adult/child 2500kr/free), which dates to the late 12th century. This historic settlement once belonged to Ingjaldur Höskuldsson, a character in Njál's Saga. The structure is managed by the National Museum and has interesting historical exhibits and a pastoral setting. It's only open to visitors during the summer, but you can see their exteriors all year.
