Duus Museum is the Art and Cultural Center of Reykjanesbær. It houses the exhibition halls for the local museums, concert halls and halls for mixed cultural activities. Café Duus offers refreshments.
Duus Museum is located near the marina in Gróf overlooking the Keflavík bay. On the cliffs surrounding the Duus marina is an interesting foot path where one might catch a glimpse of whales swimming near by. The marina also marks the beginning of a beautiful 10 km long walk trail along the coastline of Reykjanesbær from Keflavík to Innri Njarðvík.
