FAQs about flying to San Salvador

San Salvador climate

The San Salvador climate is tropical but the key thing to remember is that there are only two seasons here: rainy and, well, not rainy. The former starts in May and carries on through the traditional Northern Hemisphere summer months until November.

Getting around San Salvador

Flights to San Salvador arrive at El Salvador International Airport, which is in Comalapa. From here it is advisable to take a taxi or rent a car from one of the many car rental agencies represented at the airport.

Many of the attractions in the city are quite far apart, making walking an unlikely transportation option. Although domestic bus services are by far the cheapest way of getting about, the service leaves a lot to be desired in terms of organisation. Destinations are rarely displayed and instead it is common for the locals to ask the drivers where their buses are going – this may work for the locals but may pose its own problems for visitors with fledgling language skills.

Driving around San Salvador poses its own problems though many of the major thoroughfares are long and straight even if the smaller streets are not, making local navigation relatively straightforward.

What is good to know if travelling to San Salvador?

  • The Joya de Cerén Archaeological Site discovered in 1976 features the remains of an ancient farming community that was buried under several layers of volcanic ash for more than a 1,000 years. The Caldera volcano erupted in about 600AD, burying the community that lived in its shadow and preserving the ruins much like those at a similar site in Pompeii.
  • Much like any major city, San Salvador is full of museums, galleries and other historic sites. The best of the lot that should not be missed by travellers visiting San Salvador are the David J Guzman National Museum of Anthropology and the Word and Image Museum though the National Theatre, the National Palace, and the National Cathedral are all also worth checking out.
  • For a change of pace from the often hectic feel of the city head for La Laguna Botanical Gardens on the outskirts of the capital where a relaxing alternative to shopping and sightseeing awaits. Situated at the bottom of a no-longer active volcano, the gardens were built around a central lake and feature a staggering array of wildlife in the form of 3,500 species of plants. These are divided into 32 categories that include orchids, medicinal plants and begonias.
  • Several areas in El Salvador are accessible from the capital and can be explored on day trips. These include La Libertad, a popular area for surfers; the Montecristo Cloud Forest which is about four hours’ drive north as well as the Maya ruins of Tazumal, which can be reached in about two hours.
  • Take in San Salvador’s upscale nightlife at the Zona Rosa. Wealthy locals and tourists mingle in the area where local favourites include Senor Frog’s, Stanza, Guadalajara Grill and Club Code. Remember that it is advisable to take a taxi back to your hotel after a night out.
