The descent finds the rocky ridge (barra) at around 16 metres, running north-east to south-west along the coast with sand on both flanks. The ridge is asymmetric, and that asymmetry is the practical navigation cue. The west flank is slightly shallower and fades onto sand more gradually - the easier side to slow down over, with octopus and scorpionfish in the rock and the occasional buried ray where it meets the sand. A 2013 sighting of a buried butterfly ray was found in exactly that kind of spot, with only its eyes and tail visible above the sand. The east flank is steeper and deeper - around 25 to 26 metres at the base - with bigger blocks and crevices, and reads better for wide structural photography.

Most groups follow one flank for the outbound leg and return on the other at shallower depth, with the boat's anchor line as a navigational reference. Centres typically run a line across the ridge from the anchor so divers exit on the opposite flank from the one they entered on. Bottom time on a 26 metre profile is typically 48 to 60 minutes, which is tight on air alone. Nitrox is the local norm for full coverage.

Visibility is the variable that matters most on this stretch of coast. A respectable 8 to 10 metres is typical, but it can crash to 4 metres in winter or after rain, and summer-calm exceptions reach 18 metres or more. Conditions on the descent are not always conditions on the safety stop.

The rocky ridge is a documented nudibranch observation site for the local Catalan species record, with Godiva Taronja (Dondice banyulensis) and Hypselodoris picta both photographed here across more than a decade. A diver carrying a macro lens has a reason to slow down here that does not apply to most other ridges in the Port Balis rotation. Spiny lobster density can be unusually high in localised patches: one diver counted five large individuals in a few square metres on a single visit, well above the typical area baseline. Older dive logs and blogs from the early-to-mid 2010s also describe a small religious figure on concrete blocks beside the natural ridge — a nativity-style scene that gave the site its name. Whether that placed feature is still in position today is unclear; recent dives have not confirmed it. The name has stuck regardless.

Surface chop is common on this coast and conditions below are usually unaffected. The typical pattern is calm at the bottom under a building Garbi (south-westerly) wind by mid-dive. Boarding back onto the boat is where the surface state actually matters. Visibility can drop without warning, so a compass and SMB belong on every dive on this profile. There is no fixed mooring; centres typically run a line across the ridge from the anchor to keep return navigation clean. Calibrate the exposure suit to the bottom — the summer thermocline drops bottom temperature 4 to 7 degrees colder than the surface band at 22 to 26 metres. Nitrox extends bottom time at depth and is widely available at both Port Balis and the Mataro port.
