How do I get around El Salvador?

Getting around El Salvador is manageable given its small size (roughly the size of New Jersey). From the international airport (SAL), the coast is a 30-60 minute drive. Options include: Uber/DiDi operate in San Salvador and to/from the airport ??? the cheapest option for airport transfers ($15-25 to the beach). Rental cars cost $30-60 per day and give maximum flexibility; roads are paved and well-signed on main routes. Local chicken buses (repurposed US school buses) are dirt cheap ($0.25-1) but slow and crowded. Modern air-conditioned microbuses run between major towns for $1-3. Shuttle services connect tourist destinations for $10-25 per person. For the coast, many surf resorts offer airport pickup. Within beach towns, everything is walkable or reachable by tuk-tuk for $1-2. Domestic flights don't exist (the country is too small), so all travel is by road. Traffic in San Salvador can be heavy during rush hours.
