Wild camping in Ireland is limited and not generally permitted by law, which is why it can be hard to find clear options. However, it is sometimes tolerated in remote areas if done responsibly. For a 3 to 4-night hiking or backpacking trip, suitable areas include remote mountain or coastal regions where there is low foot traffic. You must camp discreetly, stay well away from houses, farmland, and roads, and always ask permission if land ownership is clear. Leave no trace, avoid fires, and move on each day rather than staying in one spot. Be aware that the weather can change quickly, even in June, and ground conditions can be wet and boggy. Routes are often not clearly marked, so strong navigation skills are essential. Water is usually available from streams, but it should be treated. If you prefer a legal alternative, some long-distance walking routes have nearby campsites or informal arrangements with landowners, which can still give a remote, multi-day experience without breaking regulations.
