Storaberget offers challenges and experiences for both large and small hikers. From Hogstad, follow the farm road sign no. 400-416 to the first farm on the left-hand side. From here on a cart road in the pasture to the waterworks from the days of the war. Follow the signs for Storaberget further in an easterly direction to those to Lomstjørna. There is a path further between the pond and over voices in the southernmost pond. From here the clear path to the ancient fortification. From the fortification, there is a clear path further up to the highest peak on Storaberget. Return the same way. The most eager can extend the trip to a round trip where you get to see Grinavatnet. Signs stand by the inner Lomstjørna.
Sandnes waterworks did not have the capacity to meet the Germans' need for water. As early as 1941, the Germans, therefore, planned their own waterworks. The choice fell on the Grinavassdraget which consists of Grinavatn and Lomstjørn. The capacity was estimated at 800,000 cubic meters per year. The water was of excellent quality and the waterworks had something as rare as an alkalization plant. The stone house that housed the facility stands to this day. The water flowed through crushed marble so that it became less acidic. The water was led in a tunnel to a pressure basin above Hogstad, from here in a ten-inch main line to Sandnes. The main line was 10 km long, half wooden pipes. These waterworks supplied Sola with water until 1959.
