La Zarza is a beautiful ravine full with dense laurel forests, fern covered undergrowth and steep rockwalls and caves. The area was home to the original inhabitants of La Palma, called the Benahoares. They left several circular markings on the steep rockwalls and lived in the surrounding caves. The area is, due to its dense forests, a beautiful area for birds and home to a great variety of species.
Both endemic pigeons can be seen: Bolle's Pigeon and Laurel Pigeon. Many small songbirds are mostly present in combined flocks, consisting of Chaffinch, African Blue Tit, Canary Islands Chiffchaff and Goldcrest. Sometimes a Sparrowhawk might show itself.
Above the forests, small flocks of Plain Swift can be seen.
The area has a visitors center and you'll have to pay a small entrance fee to enter the park. You can park your car at the center and walk a circular route through the park.
