The Coaster (train) is near the airport. Just get a ticket to Oceanside. If in doubt there at the station, just as a ticket agent. If going by car. Take I-5 north. Takes about 40 minutes to get there. I believe there is a USO branch within the airport; there may actually be a military shuttle up to Pendleton.
If you re in the military why don t you just ask your command about a duty driver? That doesn t cost anything at all. Or if you want to try a base shuttle you d do it through one of the local bases, like Miramar or possibly even NAVBASE San Diego.As a side note, if you re heading to Pendleton because it s your orders then cost shouldn t matter. Mandatory relocation is reimbursed.
exit the airport onto Harborturn Left onto Grapeget in the right lane and go onto 5 Souththen merge onto 163 Northmerge onto 805 Northmerge onto 5 Norththis will take you to the Camp Pendleton Exit, when you see hwy 78 you know you are close.it should take you about 45 min to 60 min to get there
