taking a bus to Troncones

Took this trip twice this year. Catch the "La Union" van at the transport hub in Centro on Av. Las Palmas just off Av. Benito Juarez. The cost in early March 2019 was $31 MXN pesos. Tell driver to let you off at Troncones stop. Once off the van, cross the highway, walk to the Pemex gas station (on the left side of the road) and wait for another van marked "Playa Troncones" to stop and pick you up. (Or, you can keep walking a little further and wait for the van at bus stop "caseta" on the corner of the road that goes directly into Troncones.) The fare to the end of the line (Punta Mahajua) was $24 MXN pesos. The fare to downtown Troncones is a little less. The last van leaves Punta Mahajua in Troncones at 5:00pm for the return trip. Hope this helps.
