The village Grenivík is a part of Grítubakkahreppur district in eastern Eyjafjörður fjord. The population is about 377, close to 300 in the village and another 100 in the countryside south of the village. The village is below the 1167 meters high mountain Kaldbakur. There are interesting hiking routes up the mountain, and for those who prefer easier hikes Þengilshöfði is a good option. Mount Þengilshöfði is 260 meters high south of Grenivík. Other mountains in the district are a challenge to climb such as Blámannshattur and Laufáshnjúkur.
Grenivík is not far from some of Iceland's most popular hiking routes. Látraströnd and Fjörður district used to be inhabited. The last farms in Fjörður were abandoned in 1944 and only one farm in Látraströnd is still habited. This old and abandoned district is a paradise for hikers and getting more popular every year. It's very beautiful and full of history.
There are many places in the district of interest for the tourist. Laufás is one of them, a historical farm and church site. There is a Folk museum in the old farmhouse belonging to The National Museum of Iceland, open to the public.
