The cliffs are why people come; the walk out to them from Doolin and the limestone country behind are what turn it into more than an afternoon.
Cliffs of Moher Experience
Open daily 8am–7pm. Book a timed slot online — it is substantially cheaper than the gate price — and the ticket covers parking, the visitor centre and the cliff path. Early morning and evening are far quieter than the 11am–3pm coach window.
Cliffs of Moher Coastal Walk
A waymarked clifftop path linking Doolin to Hag's Head by way of the visitor centre, roughly 13km end to end and unfenced in places. Most people walk the Doolin-to-centre half and arrange a lift back. Check conditions first; it is exposed and shuts in high wind.
Doolin Ferry to the Aran Islands
Sails from Doolin Pier: about 15 minutes to Inis Oírr, 25 to Inis Meáin, 35 to Inis Mór. A combined ticket lets you spend the day on an island and take the 50-minute Cliffs of Moher cruise on the way back, which shows the cliffs from sea level.
Burren National Park, Mullaghmore
Free, with an information point in Corofin and a free hop-on shuttle to the Gortlecka trailhead running daily May to September, every 30 minutes between 9.30am and 4.45pm. The Mullaghmore loops take 2.5–3.5 hours over limestone pavement; the orange and white trails take under an hour.
Doolin Cave
A show cave at Craggycorradan East, five minutes from the village, built around a 7.3m stalactite. The tour drops 125 steps underground to a constant 11°C, so bring a layer, and booking online is sensible in summer.
