If you have several days, it is recommended a visit to the Visitors Centre Juego de Bolas, where, not only will you get information about the most singular aspects of La Gomera, but you can also plan your visit with the help of the reception staff. In the same day you can enter in the park through any of the circular or linear trails of easy access and low difficulty level. Also bear in mind that in the environment of the national park there are restaurants that offer traditional food of the Canary Islands and of La Gomera in particular.
Depending on the time available, excursions can be designed with the help of the map of the park. The network of trails of the park is composed of 18 routes, but in the rest of the island there are dozens of trails of great interest. Remember not to walk alone and carry with you water, some food, warm clothing, a hat and sunscreen.
For more information, see the web page of the Cabildo Insular de La Gomera http://www.lagomera.travel/es/explorar/senderismo-en-la-gomera.aspx.
Whether you are going by car until the trails or if you are walking in paths aside from the ones of the mountain, it is not bad idea to always take a swimsuit and a towel, as both if the road ends at the coast (caution when bathing in the sea, especially in the north coast), or if you have travelled by car to the park and then go to some coastal town, the island is comfortable enough to, in the morning, be engulfed in a jungle, filling your boots with mud, enjoy the local cuisine in one of the varied restaurants of the island and finish with a siesta on the beach with a bath included. The Canary Islands allow you to enjoy the beach almost every day of the year.
If the day of the visit is a Friday (also Wednesday in summer), you can book a guided tour of the national park http://www.reservasparquesnacionales.es/real/ParquesNac/index.aspx. If the dates don't coincide or you prefer to walk for several days, it is feasible to hire the services of local guides in any of the companies of walkers.
When the visit is in the summer, it is highly recommended that you attend one of the many patronal feasts that are all over the island, where you can enjoy and learn about peculiar town festivals with pilgrimage, cultural and sporting activities, not forgetting, of course, the dances with orchestras of La Gomera, without a doubt the most famous of the Canary Islands.
Spending more than a day exploring the Park will also allow us to taste the island cuisine in the restaurants and eateries in the vicinity. You can't miss the almogrote, the potaje de berros (watercress soup) or the leche asada con miel de palma (a desert, made of roasted milk with honey of Palma).
