Transportation in Tenerife is relatively cheap and convenient, with the option of using local buses or taxis. A taxi ride from the airport to Santa Cruz costs about $20, and local buses are available for about $3 per ride. Renting a car is also a good option for more flexibility but may be a bit more expensive.
If you have more time, you can consider visiting the Anaga Rural Park with its beautiful natural landscapes and hiking trails. However, for those with limited time, you may consider removing a destination or two from the itinerary to have a more relaxed and comfortable trip. Alternatively, adding one or two destinations to the itinerary will make it even more interesting.
