The magnificent boat trips to the Vestmannabjørgini (Vestmanna bird cliffs) and grottoes are a popular excursion in the Faroe Islands. On the boat you experience deep grottoes, narrow straits and 700-metre high cliffs soaring up from the ocean. These cliffs and caves provide safe nesting places during the summer months for thousands of sea birds such as puffins, razorbills, guillemots and fulmars. In the past and also to some degree today locals would climb down the cliffs to collect bird eggs, which are considered a delicacy by the Faroese. The boat tour last approximately two hours. There are several tours daily from May to September.
