Getting there & around
Buses to Terminal de Oriente in San Salvador (US$0.80, 1½ hours, every 15 to 20 minutes from 4am to 6pm) leave from the corner of 1a Calle Pte and 4a Av Sur, a block west of Parque Centenario. If you're headed north, catch bus 163 to Aguilares (US$0.68, 45 minutes, every 40 minutes from 4:45am to 6:10pm) and transfer to a bus to Chalatenango (bus 125) or to Las Palmas and El Poy (bus 119). On the return, the last bus from Aguilares to Suchitoto leaves at 6:15pm.
If driving to San Salvador, consider going west from Suchitoto to Aguilares and then south on Hwy CA-4. This brings you into the city from the north - follow signs to Hospital Bloom if you're headed for the Blvd de los Héroes or Colonia Escalón areas - instead of from the east through more dangerous and congested areas, like Soyapongo and the centro.
Boats take passengers from Suchitoto across the reservoir to San Francisco Lempa (per person US$5, 20 minutes). A car ferry (per person US$1, per car US$4) makes the same trip, albeit less frequently and less quickly. From the pier on the other side, it's about 500m up to the bus stop for Chaletenango. Although this route is shorter, it is almost always quicker to get to Chaletenango by bus via Aguilares. Then again, the boat is more fun.
