The nearest airport is Alicante-Elche (ALC), about 98 kilometres from Jávea and roughly 70 to 75 minutes by car. Valencia (VLC) is further away, about 120 kilometres, which works out to just over an hour and a quarter to an hour and twenty minutes on the road.
You can also get here without a hire car: ALSA runs its regular line between Alicante and Jávea more than 13 times a day, and on weekdays it also goes direct from Alicante airport. An alternative is the bus to Dénia, with a connecting ride of about 40 minutes to Jávea's bus station. From Valencia Airport, ALSA runs direct to Jávea four times a day, a journey of about 2 hours and 50 minutes. Jávea has no train station of its own: the TRAM between Alicante and Dénia ends at Dénia's harbour, and while Gandía does have a train station towards Valencia, there is no train to Jávea from there either, only a connecting ALSA bus.
Within the town itself, the local Toscamarbus runs one fixed route between the old centre, the port and the Arenal, with an extension to Toscamar and Cala Blanca, for a flat fare of 1.65 euros a ride. Walking works too: the old centre is about 2.5 kilometres from the port, some 25 to 30 minutes along a mostly flat path, and the port is about 3 kilometres from the Arenal, roughly 35 minutes further on. For the more remote calas such as Granadella and Portitxol, and for most rural accommodation, a hire car is genuinely useful, but for getting between the town's three hubs, the Toscamarbus or simply walking is a real alternative.
