T1D in Hawaii: What to Pack, How to Prep, and How to Stay Steady
Hawaii is one of those places that feels like a reset button—warm air, insane ocean views, and a slower rhythm. For those of us living with t1d, it can also bring a few unique variables: heat, humidity, long beach days, hikes, and time-zone shifts. Here’s how I plan (and what I wish I’d known) to enjoy Hawaii like it should be enjoyed while keeping blood sugars steady and stress low.
Before you go: prep that makes the trip easier
Pack more supplies than you think you’ll need (I aim for 3x). Split them between carry-on bags so one lost bag doesn’t ruin the trip.
Bring a small “beach kit”: fast carbs, glucose tabs, a mini sunscreen, and a waterproof tape or cover for your insulin pump.
If you use insulin pens, consider a cooling case—cars and beach bags heat up fast considering Hawaii's beautiful climate.
Save the nearest urgent care and pharmacy locations on each island in case of emergency.
LOADS of sunscreen if you're a person that tends to get red easily, even if you're not it's still essential to wear sunscreen!
Heat + water days: what changes for T1D
Between swimming, walking, and the heat, insulin sensitivity can increase quickly. I try to start beach days with a plan: easy-to-grab carbs, hydration, and a reminder that “feeling fine” can still mean I’m trending down unknowingly.
Keep insulin and devices out of direct sun (shade + insulated pouch) so no overheating happens.
If you're going to go into water/snorkeling which is a MUST then make sure your number is good before you go, and check in between.
Hawaii is known for its sunny skies and warm weather. However, those volcanic mountains can lead to inclement weather. The rain can come in fast and strong.
We say, just run with it! The rain is warm, and it usually stops fast.
Hikes & adventures (without the rollercoaster)
Sometimes another thrilling thing to do in Hawaii is going on hikes, as hawaii is mostly trails along the island. The island of Oahu is home to highly accessible, iconic trails like Diamond Head, while Kauai features the rugged, 11-mile Kailua Trail along the Na Pali Coast.
Carry fast carbs + a slower snack for longer climbs.
As a t1d make sure your numbers are steady before starting the hike, as your numbers will most likely drop from the terrain on the trails.
Hydrate early; dehydration can make numbers stubborn and harder to correct, especially with ketones.
Go slow, take in the view as hiking in Hawaii is one of the most beautiful things in the world to do.
Food in Hawaii: enjoying it while staying in range
Fresh fruit, poke, plate lunches, and shaved ice are part of the fun. I don’t skip the fun foods; I just try to be intentional about timing so I’m not chasing highs and lows all day.
Poke bowls: protein + fat can mean a delayed rise, watch for it later.
Tropical fruit can spike fast—pair with protein when and if you can.
Shaved ice: I treat it like a planned dessert and keep a correction strategy in mind.
Hawaii MUST Do's
ATV tours around the island, top tier experience!
Tour the Pearl Harbor National Memorial.
Hike the iconic Diamond Head State Monument.
Must go to Waikiki Beach, it's the most famous beach in Hawaii
Go to a traditional Luau, it's a fun dinner in the Hawaiian culture way, they dance and show the people their traditional dances and their stories behind each one.
Final thoughts
Hawaii is one of the most incredible places to visit! There is so much to do when you put your mind to it and don't let anything limit you, especially T1D! The beautiful culture and landscape of the islands of Hawaii are unlike you'll ever, or have ever seen before; don't let a controllable illness control you and exploring the beauties of the world.
