Things To Do on the Big Island
A Local's Insider Look at Hawaii's Most Diverse Island
Written by a Local Expert
Kalani MillerAn Invitation to My Island
The first time I stood at the edge of Halemaʻumaʻu crater at dawn, watching the earth breathe fire into the morning sky, I understood why our ancestors called this place home to Pele, the volcano goddess. The heat rising from that glowing pit wasn't just geological activity. It was the island's heartbeat, the force that continues to shape this incredible place I call home.
Welcome to Hawaiʻi Island, though most folks know it as the Big Island. I'm Kalani Miller, born and raised in Hanalei on Kauaʻi but now calling this amazing island home with my wife Alana and our four keiki. After years of exploring every beach, trail, and local spot on this island, I've learned something important: the Big Island isn't just big in size. It's big in spirit, big in diversity, and frankly, big enough to overwhelm even the most prepared visitor.
That's where this guide comes in. This isn't another endless list of every possible thing you could do here. Instead, it's my personal, honest take on the experiences that will help you connect with the real heart of this place. I've organized everything by what you're seeking: adventure, history, incredible food, family fun, or pure relaxation.
The Foundation: Split Your Stay
Here's the most important advice I can give you: split your time between both sides of the island. This isn't just a suggestion. It's essential for understanding what makes this place special.
The Big Island is roughly 4,028 square miles. That's nearly the size of Connecticut. All the other major Hawaiian islands could fit inside it almost twice. Trying to see everything from one base is like trying to explore both New York City and rural Vermont while staying in Boston. Possible, but you'll spend more time driving than experiencing.
☀️ Kona (West Side): Sun and Water
The western side is your classic Hawaiian paradise. Sunny skies dominate here, with some areas getting less than 10 inches of rain per year. This is where you'll find the major resorts, world-famous Kona coffee farms, and stunning white sand beaches perfect for swimming and snorkeling.
🌿 Hilo (East Side): The Soul of Old Hawaiʻi
The eastern side receives more rain, but that creates its magic. Lush rainforests, dramatic waterfalls, and a laid-back local atmosphere define this region. Hilo feels like stepping back in time to a gentler era of Hawaii. It's your gateway to Hawaiʻi Volcanoes National Park.

How This Guide Works
The Big Island contains 11 of the world's 13 climate zones. You can start your morning in a tropical rainforest, drive through a volcanic desert by lunch, and watch the sunset from a snow-capped peak. Five massive volcanoes built this place: Kohala, Hualalai, Mauna Kea, Mauna Loa, and Kīlauea. Each one shaped the land differently, creating an island where discovery happens around every corner.
Getting Around
Rent a car. This is non-negotiable. For most activities, a regular car works fine. But if you want to reach places like the summit of Mauna Kea or some hidden beaches, you'll need a 4-wheel drive vehicle.
My Promise
This guide will help you cut through the overwhelming choices and experience the island's authentic spirit. No generic recommendations. No outdated advice. Just the real Big Island, seen through local eyes.

It surrounds you with it.
