Walkways and footpaths within town limits are excellent; work is ongoing to mark and connect them into a coordinated whole.
Somewhat to the north of town is one of the country's largest geothermal areas, Hengill, where steam plumes can be seen for miles. Hiking and riding trails stretch from the town throughout Ölfusdalur valley, into the Hengill volcanic area, and to the Nesjavellir geothermal and Þingvellir National Park. Along the way are warm springs in Reykjadalur where bathing is possible.
