SURPRISE MAINLAND PACKAGE

SO THAT WAS a dive to forget, although of course I’m duty-bound to record any unusual experiences for divEr readers.

The first dive had been to the same sort of 40m depth, with James and Vicky and setting out over sand from the mooring point and heading down onto a sheer wall.

The fish down on the wall were isolated examples of the main species you get used to seeing in these waters – the very colourful ornate and rainbow wrasse, handsome painted combers amid the swarming black Mediterranean chromis.

The sponges were as profuse and colourful in crimsons and golds as I’d been promised, with here and there a fireworm or starfish to be seen, and after ascending it was pleasant to explore the various gullies on top of the wall.

At Zeus’s Labyrinth in the 25m range there were some nice little swim-throughs complete with moonpools, and small sting rays rose out of the sand when disturbed by the passing of a diver.

At the multi-level site called Aquarium, I struggled on my first foray to focus even on inhabitants as big as moray eels, thanks to a baffling and infuriating fogging problem with my trusty old Bigeye mask.

After a while I came up, swapped it, and went straight back down for another crack at Aquarium on my own in the shadow of the boat. I had a relaxing time shooting fish portraits at this well-named site – the craggy topography gives it interest, and while the fish might be small they were plentiful and colourful, with the wrasse, combers and damselfish but also quite a few silvery bream.

I also spotted a couple of tiny Flabellina affinis, the spiky violet-coloured nudibranchs common in parts of the Med.

Epidive does a lot of try-dives for visitors. I missed the one it did during my stay for the town’s kids, which sounded like a cat-herding exercise, but did join in the fun when a boatload of mainly American students on a yoga-retreat holiday in Epidavros opted for a day of activity. Most of them were going beach-cleaning, but half a dozen wanted to try diving too. This they did from one of the boats in a shallow, sheltered bay.

Rather than an awkward boat-entry the kits were fitted to the swimmers in the water – a good arrangement, and the students all seemed relaxed.

Only one of the new divers decided after a brief immersion that beach-cleaning would be a preferable pastime, but the others were clearly buzzing.

Jolisa, an environmental-science student, had dived before – six times in a cold Pennsylvanian lake – so she was able to join Yves and me on a quick underwater clean-up in slightly deeper waters over damsel-dotted seagrass beds.

She flitted about tirelessly, picking up more discarded items than Yves’ bag could hold, as if she did it for a living.

Later we joined in cleaning a tiny beach often used for barbecues and picnics. It looked fairly innocent of litter as we swam towards it, but very different at close quarters.

The shock came as I realised that even with many bags filled, mainly with plastic bottles, we had merely scratched the surface. But the enthusiasm for the clean-ups under a blazing sun was good to see.

the last diving day was one that sticks in my mind. The Aventis III was an 85m cargo ship, 27 years old when, in the early hours of a November night in 2004, she hit rocks off a small island west of Agistra, some 15 miles from Epidavros.

The weather was fine and it was a clear night. Word is that the captain was being distracted by a lady in his cabin at the time.

The vessel lies to port bow-uppermost at 18m, this section clearly visible from the dive-boat through the crystalline waters. The stern rests a shade short of 50m, so there’s something for everybody at the site.

We trailed across the expanse of the starboard side of the hull, over the bridge and down towards the seabed, where various deck items have ended up, before weaving back up in leisurely fashion over the decks. There was plenty to explore on the intact wreck, after which we spent time degassing on the rocks. That sinking was a boon for divers.

Later we headed for a site north of Epidavros – Yves doesn’t advertise the exact location of his “minotaur cave”, and for good reason. We moored close to the entrance, a long slit at about 5m deep towards the base of the wall.

Pre-warned, I had added a shortie to my 3mm wetsuit and a hood too. I was glad of the precaution as I followed Yves through the crack and into a mind-warping thermocline.

On the other side of this liquid barrier, warmish saltwater had been exchanged for a shock of cooler water at about 14°C.

Any chill was quickly forgotten in the excitement of being in the extensive cavern that now presented itself. The lights of our group of four illuminated a sculpture garden of ancient stalagmites among grey slabs and boulders, and sent shadows chasing around the walls. These confused the eye; I was hoping to see fast-moving things, but not shadows.

THEN YVES’ LIGHT picked them out, not shadows yet wraith-like – big seals, two of them, flying along the walls very fast, nose to tail. The chamber was too big  for my camera to catch more than a shadowy glimpse. We carried on, parallel to the sea and only now could I make out the narrow blue windows far off to my left.

We passed through a small thermocline and into a further chamber. There was a large moonpool in here, but as we rose into it Yves indicated that it would be a bad idea to remove our regs. The space held an unhealthy measure of seal-gas.

Back in the first chamber we saw the flying seals again. And then again, heading the same way as us but racing ahead of our slow procession – only this time there were three of the phantom shapes, one a little smaller than the others.

This surprised even Yves, who had expected to find no more than two. They turned out to be a pair with a large child.

These were no ordinary seals, either. Mediterranean monk-seals have the distinction of being earless, and count among the world’s most endangered marine mammals. There are reckoned to be no more than 600 left around.

Once before in a cavern in Madeira a lone monk seal had startled me by emerging from nowhere and whipping past my shoulder, so I knew how fast they moved – I hadn’t been able to photograph that one either. But I hadn’t expected such a soul-stirring experience in Epidavros.

Monk seals are said to be making a bit of a comeback in the Aegean, which is why Yves’s secrecy is a sensible precaution.

People who get a kick out of spearguns exist in greater numbers than do monk seals in these parts, so it’s advisable to keep them well apart.

THERE IS PLENTY to enjoy when not diving, not least the two ancient theatres, still used for concerts, built in the 4th-century BC and later extended by the Romans. One is close to Epidavros town and the much bigger one, able to seat 14,000 people, is a drive away to the west.

This is a wonder – the acoustics are such that they say you can hear a match struck centre-stage from anywhere in the vast space. Beside it are the remains of the Asclepeion, a sort of hospital-spa resort complex. It made this part of Greece famous in classical times, attracting people and their wealth from all over the ancient world to stay and sample its cures.

Today’s Epidavros can still offer divers an attractive rest-cure, I reckon. I’m no doctor, but I would prescribe it.
