Waialeale Blue Hole and the Muliwai Trail

Hawaii Hiking Trails

Blue Hole in Waialeale Canyon (Kauai)

Blue Hole panorama, Waialeale Canyon

Distance: ~14 miles roundtrip if walking the access road from Keahua Arboretum
Trailhead: Parking lot at Keahua Arboretum, follow 580 west from Wailua until reaching the stream crossings. If you have 4WD you can continue further along the access road to reduce about 6 miles of road walking
When: Rainfall in the canyon is spread out evenly throughout the year raining an estimated 300+ days per year

The trek to the "wettest spot on earth" is mostly rock hopping up the Wailua River. The river leads to the Weeping Wall, a cascade of waterfalls down the Waialeale Crater. Access to this hike is difficult so you likely will have the canyon to yourself. Helicopters overhead are seen throughout the day as the canyon was the backdrop for the Gate opening scene in Jurassic Park

Jurassic Park Gates

I parked at the Keahua Arboretum at the end of 580 and walked the extra miles in the morning. There is a good overview map on HawaiiGuide.com with landmarks such as stream crossings and the Jurassic Park gate to help with the access road

Guardian falls on the Wailua River in Kauai

After reaching the end of the road, stay alongside the river until reaching this waterfall known as Guardian Falls. The correct paths should always be within listening distance of the main Wailua. If needed walk in the river itself until a path is spotted and avoid taking one of the hunter trails deeper into the forest. Climb the path on the left side of the picture above and continue along the stream in the center of the frame

The paths are less defined after Guardian Falls, pink flags have been mostly removed as of May 2019

Walking up the northern stream to the gate

The easiest route is following the main stream in the northern canyon, a waterfall will come into view on the north face of the crater

Gate on the Blue Hole hike in Waialeale canyon

The northern stream leads directly to a gate in the fence, which was installed to keep hogs and goats from the Inner Sanctum. The gate is a good landmark as there is a well defined path for the remainder of the walk

Weeping wall hike to the Blue Hole in Mount Wai'ale'ale in Kauai Hawaii

The sun came out when I reached the weeping wall cascade in the back of the Wai'ale'ale crater

Looking back on the Waialeale hike from the cascade at the Blue Hole in Kauai Hawaii

Both times I have done the hike I waited for a good weather. Flash floods are possible, best to check the summit forecast. The Waialeale summit averages 20-30 inches of rain per month. The coastal town of Wailua only ten miles away averages two inches of rain per month

Muliwai Trail (Big Island)

The Muliwai Trail on the Big Island starts with a walk across Waipio beach (18 miles return)

I parked at Waipio Valley Artworks (for a daily fee), no overnight parking is allowed at the Waipio Overlook

There is a side trip to a waterfall over some rocky terrian at Waipio beach

The trail climbs at the end of Waipio Beach and goes through the jungle. There are many streams to cross on the trail

The final set of switchbacks gives the first view of Wai'ilikahi Falls and the Waimanu Valley

Waimanu creek is the final river crossing to reach camp

Waimanu beach

I mostly rested on the day in the valley, the weather was perfect

Wai'ilikahi Falls hike from the campground

I was excited to find this large swimming pool at the base of Wai'ilikahi Falls, the water was very cold!

Much like the Blue Hole hike, there are helicopters above every fifteen minutes. The trail that leads to the falls is faint and starts near campsite #9. I had some encounters with wild hogs, but they were skittish and ran away

Lava Flow (Big Island)

Several flows were going into the ocean from a shelf collapse the week before I arrived to the Big Island (May 2017)

There were no surface flows in the park during my visit, the best way to view the lava was from the ocean on a boat

There was also a distant viewpoint from land, above is the steam cloud on the hike from western end (Chain of Craters road)

The hike was shorter coming from the eastern Kalapana side (8 miles return). I rented a bike and covered most of the distance on the emergency road

One hour before sunset (no lava visible)

Haleakala Sunrise Bike Tour

The stars before the sunrise are impressive as well. Haleakala Bike Co. allows you to bike down at your own pace, instead of with a group, which allows you to stop halfway to rest your hands (from braking) at Kula Lodge for breakfast.

Kalahaku Overlook

Awaawapuhi Trail

The Awaawapuhi trail leads to this viewpoint

Kalalau Trail

Should probably best be done as a backpack trip. I walked the 22 miles in one day, skipping the side trip to Hanakapiai Falls. A permit is required for dayhiking beyond the six mile mark.
