The Waipio Valley Lookout is a 300-foot walk from the parking area here and a fantastic view point at the end of the Hāmākua Heritage Corridor drive. The Hāmākua coasline is not only beautiful but sacred. The Waipiʻo Valley was the home of King Kamehameha I, when he was young.  Kamehameha I was the first ruler of the Kingdom of Hawaiʻi and this area is marked as an important center for political, cultural, and religious life on the Big Island.

Look for the stunning blooms of naturalized Grevillea Robusta, or silk oak, trees if running on the Silk Oak Trail between September and November. Their flowering transform the reserve into a scenic wonderland during these months. Also called silver oak, their prominent presence lends beauty alongside the trail named for this Australian native.

The Waipi‘o Valley Lookout offers stunning vistas of the ocean and the beautiful valley below. Take in the views from the observation deck and use the conveniently located restrooms, if needed, at this must-see stop. On clear days, you can spot the waterfall cascading directly off the cliff into the ocean.

Kalōpā Nature Trail is a very easy hike in the Kalōpā Native Forest State Park and Recreation Area. The beautiful walk through rainforest does not include any elevation gain and is therefore suited for families. Along your hike you will spot many different forest trees, shrubs and ferns.

The specified trail is the road into the valley. Unfortunately we didn't find another way in the jungle. Since the road is only usable by 4x4s (with reduction gears and LOTS of ground clearance) as mentioned here, there isn't much traffic.

What kind of terrain can families expect on these trails?

Families can expect lush, shaded rainforest paths with dense native ʻōhiʻa and fern species. Many trails feature a cool, damp climate due to the reserve's elevation and rainfall. You might encounter gentle elevation changes, gulch-rim trails, and flowing streams.

These trails have minimal elevation gain and are generally suitable for families with strollers, though some sections might be uneven.

Can we bring our dog on these family-friendly trails?

While the Hāmākua Forest Reserve and Kalōpā Native Forest State Park are wonderful for families, it's important to check specific park regulations regarding pets. Generally, dogs are often permitted on leash in many state park areas, but it's always best to confirm with the park authority directly before your visit to ensure a smooth experience for everyone.

What unique natural features can we see along the trails?

What is the best time of year to visit Hāmākua Forest Reserve with family?

The Hāmākua Forest Reserve experiences a cool, damp climate year-round. While there isn't a 'bad' time, visiting during the drier months (typically May to October) might offer more comfortable hiking conditions, though rain showers can occur at any time. The lushness of the forest is always present, making it a beautiful destination regardless of the season.

What should we wear for a family hike in this area?

Given the cool, damp, and often chilly climate, it's advisable to dress in layers. Bring rain gear, even on sunny days, as showers can be sudden. Comfortable, closed-toe hiking shoes are essential, as trails can be muddy and uneven. Insect repellent is also recommended.
