Sites that are especially green will soon be identified, and there is an ecological camping site close to the North Sea – Nymindegab Camping – where a solar heating system maintains the temperature in the swimming pool and indoors. The host hails from New Zealand, and his ideas about the environment and being together permeate the site, where the organic produce shop is a great success.
