One of the most developed hot spring complexes in El Salvador. Ahuachapán has the country's highest concentration of geothermal activity — the very same that powers a plant generating 25% of the national electricity.
How do I get to the Termales de Santa Teresa?
Bus 202 San Salvador → Ahuachapán, then local transport. Combine it with the Ruta de las Flores and El Imposible on the same trip out west.
