Hedinsfjordur was inhabited until 1951 when the last farm was abandoned. The main reason why the fjord got deserted was the isolation from the surronding areas, specially during the winter time, but the fjord is a known „heavy snow“ area in Iceland, with several fatal incidents recorded caused by heavy snow, snow storms and snow avalanches. Transportation were mainly through steep montain passes or by sea. Assess from sea was (and is) though very difficult since there is no actual shelter or harbour for safe landing.
It´s an good hour hike from the signed parking area close to the main road to the cache place. At the parking area you will find more informations regarding Hedinsfjordur saga and the surronding bird live. I recommend to walk the west side of the lake to avoid crossing the river were it runs from the lake to the ocean. Just follow the road towards the west tunnel and pass the fence by using the convenient stair next to the fence gate. Pedestrians are allowed to pass the gate and the area though it´s privatly owned. A visual track will take you the correct way from the end of the road but please avoid to cross the fenced private land around the only summerhouse on this side of the lake. You can easily pass it by the water shore line. It´s an easy hike, appropriate for most people but be ready to cross wet land and small creeks and remember that wether changes consistently in Iceland. Pack something to eat, warm drink, a camera and the good geocaching mood J I recommend to spend some time to experience the nature, the waves / surf at the shore and the drift wood given back by the ocean along with all kinds of stuff which somehow ended up in the ocean. Note that fishing in the river, lake and sea is forbidden without permission from landowners.
The cache is a medium sized plastic container, containing a log book and a pen. Please bring your own pen/pensil though just in case. Feel free to leave trackables and collectibles. Just find your way to the remains of an old rock laid sheep fold and start searching. I have added a spoiler picture to avoid the wall remains to be destroyed, though it shouldn´t be necessary. Please put the cache box back in the plastic bag, place exactly were it was and cover it with rocks to protect it from the harsh wether and possible mugglers.
