We stayed a few days in Salthill Caravan Park last week.
Overall, very clean. Nice facilities. Not too close to anything really unless you like to walk and get buses. Bus to Eyre Sq right outside the gate.
Thats sadly where the good news ends. The cost.... madness. We stayed 3 nights. €132 for 3 nights. Dogs? €5 EACH per night!
Showers? €1. (Very clean) but extra and buys you a very short time! Washing? €10 a token! Drying? €10 a token.
Mental. I was on the service bay talking to a guy that paid the extra for their 2 dogs. He challenged the girl at the desk, she said (and I know this is hearsay) that their thinking behind charging for dogs is that if you left the dog in a kennels you would have to pay €10 or €15 a night and that's the reason they charge what they do. There are no facilities provided for the dogs for this charge.
All in all, the site is nice. But €44 a night for a camper and 3 people. Absolutely nuts! On that basis alone, I Will not go back.
