Portroe is an inland site in an old quarry in Tipperary. It’s not too far from Dublin, usually has good clear water, and offers a range of depths going from 3m to 39m. It has recently (2010) opened as a dive centre, having been used unofficially by various clubs – including DUSAC – as a training site in the past. It now has a platform for getting in and out (the mud bank is no more) and offers fills


Andrew Thomson recently brought a club group to Portroe (Oct 2011). If planning to dive there, contact the dive centre to check on opening times and documentation required.


No need for these here!


The site is a disused quarry flooded by a freshwater spring. The area is fairly compact, and has different levels for training dives at varying depths. Interest is provided by an assortment of sunken things including an old boat and – from memory – a van and a car, as well as the old quarry workings.

Visibility is generally good: the website reports 3m to 15m, and anecdotal reports from old DUSAC divers say it’s generally towards the higher end of the range. The water does get very cold in winter, though, with temperatures from Dec to Feb often around 4 degrees C.


Rates are available from the dive centre website. As of Aug 2011, dives were 20 euro per day, or 15 per person for groups of over 10. There’s an annual fee of 5 euro too, and fills are charged at 5 euro each.
