The capital is known as a venue for one of the biggest carnivals in the world, which involved up to a million people each year (http://carnavaldetenerife.com).
Despite the location on the coast, there is no promenade in the city. 90% of the shoreline occupied by the port. This is clearly seen from the observation deck Mirador La Cruz, which can be reached by car.
Unfortunately, ports are the problem of many southern cities.
Therefore, just a few hundred meters for the promenade.
In order to somehow fix that, was built a symbol of the city and all the Canary Islands - Auditorio de Tenerife. Spain is famous for its architectural innovations, so it is not surprising.
The hill in the distance is a botanical garden. Between it and the opera are the outdoor pools. Two high houses are the highest twin towers in Spain (120 meters).
There is no beach in the city. Although this is not a problem, as the best beach on the island - Las Teresitas is not far away.
An unusual attraction behind the opera - pictures on the rocks.
The tram
If you want to walk around the city, then there are two places. Avenue Rambla de Santa Cruz:
And districts around the park Garcia Sanabria (Parque Municipal García Sanabria).
Pokémon Go
There are many public spaces here and few cars.
Districts around the Opera are not touristic. But if you come for shopping, then it's the right place. There is also a bus station and the ferry ticket office not far from the Auditorio.
Few quarters of the old city can be found around the Plaza de España.
