The blaze took place at Happy Valley Caravan Park in Porthcawl at lunchtime on Saturday.
The fire service, which sent three crews to the scene, was faced with a well-alight caravan, which it spent the best part of two hours extinguishing.
Police were also at the scene, and said a man and a woman were taken to hospital, where they currently remain.
A statement from South Wales Police read:
“Police attended following a report of a caravan fire at the Happy Valley Caravan Park at approximately 1pm on Saturday, March 1.
“A man and a woman were taken to hospital with serious injuries where they currently remain. The Health and Safety Executive has been informed and a joint investigation is underway.”
A spokeswoman for South Wales Fire and Rescue Service said:
“SWFRS received a call at approximately 1.07pm on Saturday, March 1, to reports of a fire at Happy Valley Caravan Park, Porthcawl.
“Crews and appliances from Bridgend, Porthcawl, and Kenfig Hill attended the scene and extinguished one well-alight caravan using two breathing apparatus, two 45mm jets, two hose reel jets, and one thermal imaging camera.
“The stop message was received around 2.47pm. The cause of the fire is yet to be determined.”
A GoFundMe page has been launched by Courtney Parsons to raise money for those affected. It states:
“I am fundraising for a couple who have been involved in an awful situation where their caravan and car has burnt to smithereens.
“The couple are being treated in hospital for their burns/wounds.
“This couple have lost their car and caravan and we would like to raise some funds for them to put towards getting replacements.
“Every penny will help in this terrible time.”
