Aasleagh Falls in Mayo is a stunning waterfall located on the border between Galway and Mayo. Accessible via a slightly hidden entrance point, the falls are most impressive after heavy rain. Visitors should be cautious when crossing the road to reach the viewing area, as the car park is situated on a dangerous bend. David Attenborough even made a visit here to film a segment about eels! So, if you're up for a scenic adventure and a potential celebrity sighting, Aasleagh Falls is definitely worth a visit.
