Komodo — Herp & Dive Add-On
Open

Komodo — Herp & Dive Add-On

Komodo National Park & Labuan Bajo, Indonesia

After Sumatra’s humidity bath, Komodo trades canopy roots for oceanic currents and reptilian giants. By day you trace Komodo dragons along island ridgelines with park rangers; by twilight you slide into macro mode for blue-phase pit vipers and gecko eyes glowing in beam scatter. Mixed in are scuba days on current-swept seamounts famous for mantas, sharks, and rainbow reef walls. Andrew helps guests marry terrestrial and underwater storytelling — knowing when to push ISO on a night hike versus when to sacrifice bokeh for focus stacking underwater. This segment is designed as a back-to-back add-on with Serpentine’s December circuit, but it can fill on its own for divers who crave BOTH dragons and pelagic drama.

La Paz — Magdalena Bay Sardine Run
Open

La Paz — Magdalena Bay Sardine Run

Magdalena Bay, Baja California Sur, Mexico

In late autumn the Pacific pushes vast schools of sardines into Magdalena Bay, igniting one of the ocean’s most chaotic food webs. Striped marlin ball bait, sea lions thread the chaos, dolphins herd from below, and birds dive from above. This expedition chases the energy without turning it into a stunt. Andrew’s background as a One Ocean safety diver shows up in how entries are staged: tight briefings, rotations in the water, and calm exits when predators are feeding hard. Some sessions are pure adrenaline; others are foggy mornings waiting on radio reports. That mix is the sardine run — plan for both.

La Ventana — Mobula Migration & Orcas
Open

La Ventana — Mobula Migration & Orcas

La Ventana, Baja California Sur, Mexico

Each spring the Sea of Cortez becomes a runway for one of the Pacific’s most dramatic gatherings: giant mobula rays in swirling schools, with a real chance of orcas, dolphins, and the raw energy of a working ocean. This sea safari is timed for the migration pulse around La Ventana. Days start early on fast support boats, reading surface activity and working respectfully with local crews who know these animals’ rhythms. Andrew leads with a safety diver’s mindset — clear briefings, conservative entries, and photography coaching for guests who want stronger frames without crowding the wildlife. Evenings are for debriefs, tide talk, and the slow exhale after blue water. Expect long hours on the water, seasonal variability, and encounters that can shift from quiet glides to explosive baitfish action without warning.

One Ocean Diving — North Shore Shark Safari
Coming soon

One Ocean Diving — North Shore Shark Safari

Haleiwa, North Shore, Oʻahu, Hawaiʻi

Not every adventure needs a passport stamp. Andrew’s home water is three miles off Oʻahu’s North Shore, where One Ocean Diving runs cage-free pelagic programs with Galapagos sharks, tigers on migration windows, and a rotating cast of reef species. As a long-time safety diver and PADI MSDT, Andrew is often in the water here — reading body language, managing group spacing, and helping guests settle their hearts before sharks materialize from the blue. You will hear honest ecology talks, learn why posture matters, and see how research-grade operations differ from stunt tourism. This listing exists on Andrew’s site as the “local cathedral” guests can book before or after global expeditions; commerce stays on oneoceandiving.com unless you later merchandise gift cards or vouchers in Shopify.
Duration
Half-day ocean charter (repeatable); allow 3–4 hours dock-to-dock

Confident swimmer; able to follow safety diver instructions in blue water

Sumatra — Rainforest Herping Expedition
Open

Sumatra — Rainforest Herping Expedition

Gunung Leuser region, Sumatra, Indonesia

Ten days disappear fast when you are shoulder-deep in one of Southeast Asia’s lushest rainforests. Serpentine Expeditions threads Sumatra’s lowland and montane trails in search of king cobras, reticulated pythons, pit vipers, flying frogs, slow lorises, orangutans, and the seismic presence of wild Sumatran elephants. Andrew joins as a photography-minded field partner: lighting discipline, respectful distances, and coaching for humid-lens realities. Nights belong to tracks in the mud, red flashlights, and the adrenal hush when a big snake clears leaf litter nearby. Days swap between river corridors, fruiting figs, and viewpoint hikes. This is not a luxury safari — it’s an expedition for people who want their boots dirty and their memory cards full.
Next departure

Timor-Leste — Blue Whales & Pelagic Giants
Open

Timor-Leste — Blue Whales & Pelagic Giants

Dili & offshore waters, Timor-Leste

Timor-Leste sits in the path of blue whales moving through the Banda Sea — a narrow window each year when careful, regulated surface encounters can become profoundly quiet moments next to the largest animal that has ever lived. Andrew co-leads this sea safari as Serpentine’s dive leader, pairing wildlife empathy with practical coaching for photographers. Days follow a rhythm of early launches, patient scanning, and small in-water teams so whales set the distance. Sperm whales, pilot whales, false killer whales, and dolphins appear often enough that the week feels like a pelagic festival even when blues are elusive. The tone is scientific and reverent: no heroic chasing, no guaranteed selfies — only disciplined drops when behaviour allows. Note for planners: many operators document peak blue whale activity shifting into November; we list an October departure per your brief plus an optional November 2027 backup for peak-season preference.

Before you go

Questions, answered

Do I need to be a freediver or advanced diver?

Each expedition lists recommended experience — ranging from strong snorkelers comfortable in open ocean to advanced snorkelers on faster blue-water days. Read the trip detail page for that leg's honest prerequisites.

Do I book here or with Serpentine / One Ocean?

Some trips use a deposit product on this site. Others book through partner operators when an outbound link is shown on the card. Follow the CTA on each expedition — it always reflects how that specific trip is sold.

How do deposits and balances work?

For trips sold via this store, a deposit reserves capacity on the published trip dates; balance terms are communicated in your confirmation and trip packet. Partner-booked trips follow that operator's policy.

Is travel insurance required?

Yes. Medical, evacuation, and trip cancellation coverage is required before departure on expeditions Andrew leads or co-promotes. You will be asked to certify coverage.

What if weather or wildlife don't cooperate?

Wild animals and ocean conditions owe us nothing. Andrew's teams reroute around safety and ethics first — flexibility is part of the field craft. Some days are quiet; others rewrite your portfolio.

I thought I was coming for the wildlife, but the expedition reset my relationship with freediving. Andrew was so supportive and knowledgeable — he helped me with my diving between wildlife drops. I left more confident, more capable, and honestly more inspired than I expected.

The wildlife experience was unreal. Just totally mind-blowing. You can't really comprehend it until you're there in the water experiencing it.

The trip opened my eyes to so many new things. Andrew warned us we'd all become ocean people by the end of the expedition — and he was right.

The photography was world class. It helped that Andrew gave me posing advice and met me where I was at as a diver.
