The Barranco Oscuro Nature Reserve is located in the Doramas Rural Park. Barranco Oscuro was declared nature reserve due to the fact it consists of a particular vulnerable ecosystem: a laurel forest which shelters some 40 endemic species of plants and invertebrates. The reserve is also home to a pine forest (pinar, in Spanish).
The alternatives in terms of how to get from Gran Canaria to El Hierro are rather limited, since the sea and air line companies linking the two are fewer.
Tenerife, El Hierro, La Palma, Lanzarote and Fuerteventura count as chief trip destinations within the Canary Islands for visitors of Gran Canaria.
Trekking and hiking in Gran Canaria are recommendable for people keen on active vacations. The island is well endowed for meeting tourists' expectations.
