Before visiting the Cliffs of Moher in 2026, the most important thing to know is that weather changes instantly; bring a windproof, waterproof jacket even if it looks sunny. The site is open from 09:00 to 17:00, and while the cliffs themselves are free to see if you walk in from Doolin or Liscannor, the official Visitor Centre and main parking require a paid ticket (roughly €7–€12 depending on the time of day). Booking online in advance is highly recommended to secure a parking spot during peak summer hours. For safety, stay on the designated gravel paths, as the edges can be unstable and subject to sudden, high-speed gusts of wind. Expect to spend 2–3 hours exploring, but if you plan to do the full 20km coastal walk, allow at least 5 hours and ensure you have a high level of fitness.
