Taxi from Santa Pola to Ga

[karamac24]

Hi. I would like to visit Pola park when I am over on holiday in July. As the last bus back to GA is about 10ish is anyone able to advise roughly how much it would cost for a taxi from santa Pola to top GA? Also I know there is a taxi rank in santa Pola how reliable is it to get a taxi from there at 12/1 in the morning? TIA
