Fly Fishing Christmas Island: Flats, Bonefish, and Giant Trevally

For many fly anglers, the ultimate dream is standing on a remote saltwater flat, staring into clear water, and waiting for a shadow to move. That is exactly what draws people to Christmas Island. It is a destination that feels like fly fishing heaven, where the flats go on for miles and the variety of species keeps you constantly on the prowl.

In this video, Guy Jeans takes a break from the trout water of the Kern River to explore the endless flats of Christmas Island. The trip is a reminder that fly fishing is a global pursuit, and the skills you build on your home waters can translate to some of the most exciting saltwater environments in the world.

Walking the Endless Flats

The defining feature of Christmas Island is the sheer scale of its flats. As Guy walks along the edges, he describes a landscape that seems to stretch on forever. This is where the hunting aspect of saltwater fly fishing really takes over.

Anglers walk these edges looking for bonefish and triggerfish that come up onto the flats to feed. It is a visual game. You are not blind casting; you are searching for movement, nervous water, or the subtle shape of a fish pushing up against a ledge.

But the flats are not just about bonefish. Guy is also constantly on the lookout for Giant Trevally (GTs) chasing baitfish, like mullet, against the ledges. When you see that kind of explosive action, the strategy shifts immediately. You have to be ready to drop the lighter rod, grab a 10-weight rigged with a large baitfish pattern, and make a quick, accurate cast.

The Unexpected GT

One of the most thrilling moments in saltwater fly fishing is when the unexpected happens. While targeting bonefish with a 9-weight rod, Guy hooks into a Giant Trevally.

The power of a GT is legendary, and hooking one on lighter gear is a serious test of both the angler and the equipment. Guy describes the fish jetting over the flat, completely ignoring the fact that they had been spooking bonefish earlier. Within moments, the GT pulls him well into his backing, running a good 100 yards out.

Fighting a fish of that size and strength requires patience. You can feel the head shakes, and you have to manage the runs carefully, slowly working the line back onto the reel. It is a raw display of power that you simply don't experience on a typical trout stream, and it is exactly why anglers travel across the world to fish these waters.

The Reality of Saltwater Travel

While the fishing is incredible, a trip to Christmas Island also requires preparation for the elements. The environment is intense, and Guy highlights a few critical pieces of advice for anyone planning a similar trip:

•Sun Protection is Mandatory: The sun on Christmas Island is unforgiving. Guy notes that even while staying covered up, the sun can fry you. High-quality sunblock (SPF 50 or higher), sun shirts, hats, and lip protection are absolute necessities.

•Be Ready for Rain: The weather can change rapidly. Thunderstorms can roll in and dump intense rain for anywhere from two minutes to twenty minutes. Always carry a packable rain jacket in your gear.

•Spooky Fish and Tough Conditions: Not every day is perfect. Cloudy skies can make spotting fish incredibly difficult. Guy mentions seeing several triggerfish but spooking all of them because the low light made it hard to see them in time. Saltwater fishing requires adaptability and a willingness to keep hunting even when conditions are tough.

From the Flats to the River

Traveling to places like Christmas Island is an incredible experience, but it also makes you appreciate the skills you develop on your home waters. The casting accuracy, line management, and fish-spotting abilities you hone on a trout stream are the exact same skills you need when staring down a bonefish on a saltwater flat.
