If you’re living on Guam—or just visiting—you have to check this off your island bucket list: go hiking.
Whether it’s a laid-back family outing for some fresh air or a full-on jungle adventure with your most thrill-seeking friends, Guam’s hikes are pure magic. From beachside trails to waterfall treks and mountain climbs, the island has a little something for every level of hiker. And let me tell you—catching the sunset from a mountain peak with a waterfall behind you and the ocean in view? Life. Changing.
But before you lace up your hiking shoes and charge into the jungle, let’s talk preparation, safety, and respect for the land we’re lucky to call home.
Before You Go: Plan Like a Pro

1. Do Your Research
Not all hikes are created equal. Some are chill and perfect for kids, others will test your limits and your glutes. Know what you’re getting into—how long the hike is, whether it’s steep or slippery, and if the path takes you through limestone forests or muddy riverbeds.
Start with a great resource like David Lotz’s legendary book, The Best Tracks on Guam. It’s the go-to for locals and seasoned hikers alike. Read more here.
2. Pack Smart
Bring more water than you think you’ll need. Lightweight, long-sleeved shirts, a brimmed hat, solid hiking shoes (or water shoes), sunscreen, and bug repellent should all be in your bag.
Also: a flashlight, extra batteries, a battery pack for your phone, a machete (trust me—swordgrass is real), and a plastic bag for your trash. I always toss in snacks like granola bars, jerky, or trail mix. And yes, a first-aid kit. Better safe than sorry
3. Don’t Go Solo
Guam’s hikes are often unmarked and untamed. Never go alone. Join a group or hike with a seasoned local.
A Glimpse into the Past: Hikes with History

Pagat Caves, Yigo – Moderate Ancient CHamoru latte stones, relics, and coastal caves await. It’s stunning and sacred. Please don’t take anything—not even a shell. Swim in the freshwater cave pool only if you're confident in your swimming skills.
Ritidian Point, Yigo – Easy to Moderate Trails, caves, native wildlife, and ancient village ruins. Bonus: it’s a designated National Wildlife Refuge. Call (671) 355-5096 for guided hikes. Spanish
Bridge, Humåtac – Easy to Moderate This gem from the late 1800s sits in lush southern Guam. Expect ancient trees, the possibility of spotting a deer or coconut crab, and a quiet spot perfect for a picnic.

Sigua Falls, Yona – Difficult to EXTREMELY Difficult This beast of a hike will humble you. Mud, elevation, and long stretches—some even ride ATVs in. But those cascading falls at the end? Unreal. Bring rope. Bring stamina. Bring a guide.
Tarzan Falls, Santa Rita – Moderate An ideal first hike for families. Easy to follow, often muddy, and depending on the season, the falls can be a roaring beauty or a gentle trickle. The pool at the bottom is shallow and not for diving, but still a peaceful spot to relax.
Priest Pools, Merizo – Easy A quick 30-minute stroll leads to volcanic rock pools tucked into the hills of the south. Named for Spanish priests who bathed there centuries ago, this spot is peaceful, picturesque, and perfect for beginners. Watch out for overgrowth—and don’t forget your machete.

Final Thoughts: Enjoy, But Respect

Guam’s trails are a privilege, not a playground.
Every rock, stream, and latte stone tells a story—and every wildflower, fruit bat, and muddy hillside deserves our respect. Whether you’re a history buff, a nature lover, or just someone looking to get a great workout (and even better photos), hiking on Guam offers something unforgettable.
Be prepared. Be safe. And always, always leave the land better than you found it.
