is the largest of all the caves and caverns to be found at Cap d'en
Font. Although the entrance is perhaps its narrowest point with a
width of only 9m at a depth of 10m, this huge archway with depths
ranging from 5m to 20m allows light to penetrate the cavern almost
to the rear, some 55m in. The boulder strewn floor gives way to one
of fine silt and rock after some 20m distance, and gradually slopes
upwards to a depth of 14m at the rear, a point where a single huge
rock rising to only 8m depth, sits slightly to the right. Within,
the cavern opens up so much, with its ceiling for the most part very
slightly above sea level, that it almost resembles a cathedral for
its shape and thus together with the large rock at the rear which
is like an altar, has earned its name of Cathedral Cavern.
Once at the rear, it is worth pausing for a moment with ones torch
switched off. Once the eyesight has adjusted to the natural light,
looking back towards the entrance is quite spectacular; the sheer
size of the big blue entrance archway is one aspect, however, looking
up towards the ceiling where the water breaks the surface, there is
the most magnificent royal blue reflection of the exterior light penetrating
so far in.
On the return outwards, by now swimming towards the surface another
surprise awaits. At a point within some 15 - 30m of the entrance arch
is a large surface pool of perhaps some 8m tall, within which are
numerous formations of beautiful golden stalactites and stalagmites,
one of which is almost two metres in diameter. Following this, for
the return to the open sea, it is best to swim out towards the right
hand side of the main entrance at no more that 8m depth where one
will find a small swim through that leads to the base of the cliffs
outside the western side of the cavern, here it is not unusual to
find an octopus or two hiding within small holes within the algae
covered rocky reef.
