A boy of 16 years old fell to his death on Tuesday, 29 May 2018, from a height of 100m on the cliffs above Rocha Negra, between the beaches of Porto de Mós and Luz.
Multiple authorities were involved in attempts to try to rescue him, but he was pronounced dead at the scene of the incident. Due to the difficulty of the terrain, his body had to be retrieved by sea.
He was with a teenage girl at the time. Presumably she was the one who raised the alarm. It is unlikely that a passer-by would spot a body at the bottom of the cliffs, based on personal experience.
The beach at Porto de Mós is much quieter and less touristy than Luz. Heading west from the Porto de Mós beach is a wide, flat, baked earth track. It starts a sea level, but surprisingly quickly ascends to the top of the cliffs. The track itself is 100% safe, because it is around 3m away from the edge of the cliff. You have to deliberately go over to the lip of the cliff before you are in danger.
The track runs from the beach at Porto de Mós to the trigonometry point on the hills overlooking Luz. The track is busier than one might think, for all sorts of reasons.
One is that ramblers like to do the walk from Porto de Mós to the trig point. The path is flat and the incline is fairly gentle, so it is an easy walk. An amble that is pleasant all year round. Then you come to the trig point above Luz, south of Bela Vista, and an opportunity for a chocolate box photo over Luz. The media love this as a special viewpoint.
From the trig point you have choices. One is just to do an easy amble back to Porto de Mós. Many pick this, because it is the simplest option.
If you wish instead to get down from the trig point to Luz, you have 3 alternative routes. This same choice would have faced Kate and Gerry McCann when they went jogging from apartment 4G, where they had been rehoused by Mark Warner at the Ocean Club. There are 3 routes up and down the hill. One route is a nightmare, one route is not joggable, and the third looks bad but it turns out to be easy. Mountain bikes go up and down it regularly.
I have no idea which route Gerry and Kate took.
The details of the 16 year old boy who died in the cliff fall are at best sketchy. Most of what you have in this post is local knowledge of Luz and its environs.
