My family did everything we thought was right to embark on a family hiking adventure in Captain Cook. We hiked the Captain Cook Monument trail to Kealakekua Bay in Ka’awaloa State Park.
After finishing the 3.7-mile out-and-back hike, we realized we’d do a few things differently when we get to hike it again. We’d like to share our family’s experience on this incredible Big Island hiking adventure on a trail we consider the best on Kona.
Below, I share our knowledge and tips to help make your Big Island family hiking and snorkeling adventure as smooth as possible.
Is the Captain Cook Hike Family Friendly?
First, if you’re wondering if the Captain Cook Monument hike is appropriate for a young family, my answer is 100% yes. However, you might need to reconsider if you’re not in good shape or your children must be carried.
The steep grade makes the hike grueling for some travelers, but it’s not extreme.
One of the Best Big Island Hikes
Hiking to the Captain Cook Monument offers some of the best snorkeling on the Big Island and ranks as Kona’s number one trek for my family. For three reasons, this hike has become our family’s favorite on the Big Island.
1. Adventure on the Captain Cook Hike
It offers a beautiful combination of hiking, snorkeling, and swimming.
2. History of Captain Cook
The monument marks where Captain James Cook died on Valentine’s Day in 1779.
3. Breathtaking Views of Kealakekua Bay, Captain Cook
You’ll enjoy stunning views of Kealakekua Bay, the Pacific Ocean, and Mauna Loa volcano. Below is a view of Kealakekua Bay from the sky.
Don’t leave Big Island without getting a photo of Kealakekua Bay at sunset. In Hawaiian, Kealakekua means “the pathway of the gods”
There’s also stunning views on the way to the trailhead just off Napoopoo Road.
Just check out the sunset views at Kealakekua Bay.
Getting to the Captain Cook Monument Trailhead
The hike starts off Napoopoo Road just 500 ft from the intersection with Highway 11.
Preparing for the Cook Monument Hike
1. Get an Early Start on the Trail
Starting early in the morning is essential to avoid the sun and enjoy cooler temperatures. Arriving early is also important to get a parking spot, which is limited.
We wore appropriate clothing and packed the proper hiking and snorkeling gear but did not bring enough water.
2. Bring Enough Water
The hike is moderately strenuous, and hydration is key! Aim for at least one liter of water per person every two hours of hiking.
We recommend about 4 liters (1 gallon) per person, especially during warmer months.
3. Packing Essentials to Hike and Snorkel
Here’s what we packed for the hike:
- Hiking Gear: Closed-toe shoes (hiking boots or tennis shoes), sun protection, a light jacket, and hiking sticks if needed.
- Snorkel Gear: Mask, snorkel tube, fins, bathing towel, and a swimsuit
- Extras: Snacks, sunscreen (reef-safe), bug spray, and a backup phone battery.
We also made sure to bring lunch and snacks, just watch out for the non-native mongoose to ensure they don’t take off with your food.
Captain Cook Monument Trail Overview
The trail is an old road named Ka’awaloa Road. Please note that camping, biking, or pets are not allowed.
- Distance: 3.7 miles (out-and-back hike)
- Elevation Gain: 1,256 feet
- Duration: 3-6 hours (depending on your pace and how long you snorkel)
- Difficulty: Moderate to challenging (particularly on the way back uphill)
- Weather: The trail can get hot, so start early, especially in warmer months. Check the weather and tides before you go.
Captain Cook Memorial Trail Terrain
Eight trail markers along the hike are spaced out about 1/4 mile apart.
- First Third: Lush grass and bamboo forests with a dirt path.
- Second Third: Lava rock with little shade, offering views of Mauna Loa.
- Final Third: More lava rock leading to Kealakekua Bay, shaded by trees.
Snorkeling in Kealakekua Bay
Kealakekua Bay is known for its incredible coral reefs and abundant marine life. We had the opportunity to see:
- Parrot fish
- Sea turtles
- Spinner dolphins
- Yellow tang
- Triggerfish
Snorkeling is a remarkable experience and the perfect way to refresh after the hike. Federal laws protect spinner dolphins, and snorkelers must stay 50 yards away. This law protects spinner dolphins, who often sleep in Kealakekua Bay.
To enjoy the marine wildlife of Kealakekua Bay, bring a solid set of flippers and a snorkel with a mask.
Wildlife and Nature Along the Trail
Keep an eye out for animals on the trail! Our family spotted numerous goats and heard feral pigs rustling in the bushes.
While the pigs were elusive, their presence was felt as tripping hazards on the trail.
Safety and Conservation Tips
1. Be Cautious in the Kealakekua Bay
Avoid stepping on sea urchins when snorkeling and always practice safe swimming habits. If you’re not a strong swimmer, consider wearing a life jacket or swimming with a buddy.
It’s easy to jump into Kealakekua Bay from the concrete wall, but getting out is more complicated. You’ll figure it out, but might have to maneuver to pull yourself onto the wall.
2. Respect Marine Life in Kealakekua Bay, Captain Cook
Remember not to touch or disturb marine creatures. Keep a safe distance from dolphins, fish, and coral, and refrain from feeding them.
Use reef-safe sunscreen to protect the aquatic ecosystem.
3. Leave No Trace on the Captain Cook Trail
This trail is a sacred space, so follow the seven principles of Leave No Trace. This includes packing out all trash, respecting wildlife, and avoiding damage to historical sites.
This abandoned jeep left along the trail is an excellent reminder of what not to do.
Tips for Families Entering Ka’awaloa State Park
- Bring Snacks: Kids (and adults!) will need fuel for the hike, so pack plenty of snacks.
- Take Breaks: Take frequent breaks, especially if hiking with young children.
- Start Early: Starting in the morning not only ensures cooler temperatures but also gives you a better chance of securing a parking spot and having fewer people at the reef.
Is the Captain Cook Monument Hike Worth It?
Absolutely! This hike perfectly blends adventure, history, and natural beauty. If you enjoy a mix of outdoor activities like hiking, snorkeling, and swimming, you won’t want to miss the Captain Cook Monument hike.
