1. Garajonay National Park, a UNESCO World Heritage Site, is home to the world's largest laurisilva forest, a subtropical rainforest type extinct elsewhere in Europe.
2. The park's name comes from the legend of Gara and Jonay, two lovers from different Canary Islands tribes, akin to the Romeo and Juliet story.
3. At El Cedro, you can experience ‘horizontal rain,’ a peculiar weather phenomenon caused by humidity in high-altitude clouds condensing on tree foliage.
4. The park hosts the popular 'Bajada de la Virgin' festival every five years, blending religious and pagan traditions.
5. Despite being a popular tourist attraction, the park hides the Roque El Sombrero, a less-touristy dramatic rock formation with breathtaking views.

1. Entertainment and Popular Spots: Parque Nacional de Garajonay is famous for its unique ecosystem and extensive network of trails. Make sure to visit the heart of the park, Laguna Grande, and the El Cedro Forest. Plan a guided walk or a hiking trip for a day to explore these wonders fully.

2. Money-Saving Tips: An economical way to enjoy the park is by packing a picnic lunch as there are plenty of scenic picnic spots. Public transportation is also available to the park, which is cheaper than a taxi ride.

3. Dining: There are few restaurants within the park itself. However, La Gomera, a nearby town, features unique Canarian cuisine. Try local specialties like Almogrote (cheese spread) and Potaje de Berros (watercress soup).

4. Best Times to Visit: The park is open year-round but the best time to visit is during the spring (March to May) and fall (September to November), when the weather is mild and there is low possibility of rainfall. The foggy summer season might hinder visibility but can offer a unique, mystical experience.

5. Itinerary Planning: Plan a full day itinerary for the park to fully take in its beauty. Start early in the morning to avoid crowds and have enough time for longer trails. Include Museo del Visitante Juego de Bolas in your itinerary to gain insight into the park's biodiversity and geology.
