Firefighters had been battling the blaze in Maspalomas on Gran Canaria for several hours this evening.
One person had been injured and had to received treatment for burns to their leg.
The fire broke out in a building next to Aqualand at about 5.30pm and families enjoying the water attractions were told to leave immediately before the toxic fumes engulfed the park.
Holidaymakers ran for their lives, most still wearing their swimming costumes and covering their faces with towels.
One tourist in the water park, Jorge Rodriguez said: “We were able to leave very quickly thanks to the technical and personnel team.”
A spokesman for the fire brigade said an accumulation of rubbish inside the building made the fire spread rapidly. Medics and police were also at the scene.
Fire personnel searched the premises to make sure no-one was left inside or trapped but the water park itself had been evacuated just after the alarm was raised and before the thick black smoke enveloped the site.
The intense smoke was visible from several miles away and numerous people raised the alarm.
