Boat and Air
Your options of getting to Bahía Solano are limited to air transport, unless you arrive by cargo boat from Buenaventura or hire a boat from El Valle or Nuqui. There are frequent flights with Satena and Aexpa to Medellín, and connections can be picked up from here.
By Road
The only road in this stretch of the Colombian Pacific connects Bahia Solano to El Valle. Be warned that large portions of the road are unpaved and delays are inevitable. 4x4s make the 20 km. journey in the morning for $5 per person.
