Questions people ask

How long is Howth Black Linn Loop?

The map records 8 km. Measured along the line it draws, it comes to 7.7 km. This site has not found an operator's own figure.

Where does Howth Black Linn Loop start?

The map does not name a start. The line begins 680 m from Howth, which is where the map is drawn from rather than a waymarked trailhead.

Is this the same as the other walks from here?

No. 4 waymarked routes start within eight hundred metres of the same point: Howth Black Linn Loop (red) at 7.7 km, Howth Tramline Loop (blue) at 6.7 km, Howth Cliff Path Loop (green) at 7.5 km, Howth Cliff Walk at 10.8 km. They share parts of their length and are told apart by the arrows, so the one you follow is the one whose colour you keep to.

Is it open today?

This page holds no closure notice for it, which is not the same as knowing it is open. Cliff paths and forest routes close after storms and during works, and those notices are published by the operator rather than on the map. The link above goes to whoever manages it.

Where this comes from

The route: The line, the name, the colour and the waymark are the OpenStreetMap relation relation/10812712, and can be corrected there.
Worked out here: The measured distance, whether the line is continuous, which settlement is nearest the start and every distance on this page are this site’s own calculations from that relation, last built on 2026-09-20. No climb is measured here, and no time is estimated: a walking time appears only where an operator publishes one.
