[NOTE: For those who missed the update at the top of the previous blog post, Del Viento survived cyclone Ula unscathed. We were very relieved to hear this from friends in Neiafu. Now, from California, some more highlights from our time in Tonga.]
The
rocky cliffs of many Vava’u island shorelines are comprised of limestone and
elevated coral reef rock. In some places, the rock is split or worn to create
fantastic caves and caverns. The largest and most well-known of these is
Swallows Cave.
It’s
large enough that we could dinghy straight in. That’s what we did. With our
friends aboard Vagrant, with the former crew of Wondertime, and with at least
one venomous, air-breathing sea krait (a sea snake common throughout Tonga, they
avoid humans). There was no place to anchor outside the cave, so at least one
adult hung out at Del Viento’s helm, waiting for a turn to explore.
When
it was my turn, I went with Eleanor. Once inside, after the novelty of the
echoed shouts died off, after we’d surveyed the graffiti on the walls left by
sailors from centuries past, Eleanor got ambitious and scrambled up some rocks
towards what looked like a large, dimly-lit extension of the cave. She
convinced me to go with her. I secured the dinghy, she leapt off, and I
followed, barefoot. At the waterline, the rock surface was sharp and I wasn’t
sure I could go on. But just beyond, my feet found the softest, most foot-pleasing
walking surface imaginable: hundreds of years’ of bat guano deposits. It felt
like walking on a bed of something that is cross between thick, spongy moss and
cotton candy. It covered the walls I used for balance. Don’t touch your face, don’t touch your face. I said to myself.
“Eleanor,
don’t touch your face, your hands are really dirty.”
“Okay,”
she called back. “Dad! This is soooo cool.”
“What?”
“You’ll
see.”
Then
I saw. It looked like I’d stumbled on the set of an Indiana Jones movie. The
bone props were scattered about. The obligatory shaft of light shown down through
the ceiling. Bats flew chaotically, their squeaks echoed around us.

“Stand
in the middle of the light, like you’re a goddess.”
After
about 40 minutes, our turn in the cave was up. I rowed back to Del Viento. Sara
and Leah from Wondertime followed.
Because
it was cave day, the 10 of us aboard Del Viento headed for Nuapapu Island for
another, very different cave adventure.
When
we arrived at Mariner’s Cave, there was nothing to indicate we’d arrived. The rock
and scrub brush cliffs here looked just like the rock and scrub brush cliffs that
stretched for miles. Mariner’s Cave is special in part because it’s hidden. The
only entrance to the cave is underwater and there is no evidence of it visible
from above water or on land. But GPS waypoints are published in guides and
handed down from cruiser to cruiser. We were there.
The cave
is named after William Mariner, a writer who lived in Tonga for four years
beginning in 1806. Mariner wrote a popular story about this cave. Apparently, a
young noble once hid his lover in this cave, fearing that if he didn’t hide
her, the king would kill her. Day after day, the young noble would bring his
secreted girlfriend water and food to keep her alive. Ultimately, he built a
craft and sailed her to safety in Fiji.
I
would not want to spend much time in Mariner’s Cave.
I
swam down first, trusting that the pitch dark hole in the rock, about seven
feet underwater, was an entrance to a passage that would ultimately bring me to
a cave in which I could breath. It was. And it was an experience I wanted to
share. I swam back out to get the girls.
They’d
been practicing for this. They were eager to do this. They knew some adults
were uncomfortable entering Mariner’s Cave and I think they both wanted to test
their mettle. A month earlier, Windy had worked an exercise into their school
curriculum that would prepare them.
“If
you guys can swim from the surface on one side of Del Viento, underwater and
under the keel, to the surface on the other side of Del Viento, you’re good to
go.”
Now
treading water above the entrance to Mariner’s Cave, I asked Frances if she was ready.
“Yep.”
“Follow
me.”

I
dove down and then rolled on my back so I could watch her, swimming behind me.
Soon I was in the hole, kicking my fins and moving past the sharp coral reef
rock about 8 inches above my face. Frances was still behind me. Then we weren’t
moving. I was still kicking and I could still feel water moving over my body,
but I was stationary, fighting an outflowing current. When you’re holding your
breath, and you still have a ways to go to your air source, and your progress
towards that source is thwarted, it’s not comfortable. Frances kept kicking. I
hoped she wasn’t aware that she wasn’t going anywhere. Then the outflow slowed
to a stop. We started to move. Then we moved faster, caught up in an inflow
current. The rocks sloped up. I swam upward and broke the surface. Frances
popped up next to me.
“You
did it!”
She
laughed, “Yeah. Why is it foggy?”
“Wait.”
The
thick fog inside the dark cave disappeared. Twenty seconds later, it
reappeared.
“Dad,
my ears are popping!”
“Yeah,
this cave is sealed. As the surge comes in, the water level inside here rises,
raising the air pressure—that’s what’s making the fog come and go.”
Down
below us, the underwater entrance that had appeared pitch black from the
outside now glowed like blue neon.
“Ready
to go get Eleanor?”
“Yep.”
