Makaula 'O'oma Trail - Deep Research Report

Deep Research Report

Last updated: April 23, 2026

What it is

The Makaula 'O'oma Trail is a network of hiking and mountain biking trails located within the Honua'ula Forest Reserve on the slopes of the Hualālai volcano, mauka (uphill) from Kailua-Kona on the Big Island. This area is characterized by a "cloud forest" ecosystem, featuring lush ʻōhiʻa trees and hāpuʻu tree ferns, creating a dense, jungle-like environment.

The entire trail system spans approximately 4 to 4.5 miles, but offers shorter loop options, such as 2.3 miles or 3.4 miles, allowing for varying durations and difficulty levels. Hikers can expect an elevation gain ranging from around 700 to 800 feet for the full loop. The trails are maintained by People's Advocacy for Trails Hawai'i (PATH), a non-profit organization.

Visitor experience

Visitors to the Makaula 'O'oma Trail can expect a cooler, wetter environment compared to the hot Kona coast, due to its higher elevation (above 3,000 feet). The primary draw is an immersive experience within a native cloud forest, rich with dense green ferns, trees, and other plant life, offering a "primitive jungle feel." It is particularly popular for birdwatching, with opportunities to spot native Hawaiian honeycreepers like 'apapane and 'amakihi; binoculars are recommended for optimal viewing.

The trail does not offer dramatic panoramic vistas or coastal views, but rather focuses on the intimate beauty of the forest interior. The paths are generally rough, with uneven terrain, exposed roots, rocks, and can be very muddy and slippery, especially during or after rain. The loop configuration allows hikers to choose their challenge: a clockwise direction often results in a steep descent and milder ascent, while a counter-clockwise route provides a milder descent followed by a steep ascent near the end. Feral pigs and chickens may also be sighted within the reserve.

Logistics

  • Area: The trail is located above Kailua-Kona, within the Hōlualoa area, on the slopes of Hualalai volcano.
  • Access: To reach the trailhead, turn mauka (uphill) from Highway 190 (between mile markers 34 and 35) onto Kaloko Drive. Follow Kaloko Drive for approximately 3.8 to 4 miles, then turn left onto Makahi Street. The trailhead is situated at the very end of this dead-end street.
  • Reservations/Permits: No permits or reservations are required, and the trail is generally open 24 hours.
  • Parking: Street parking is available at the end of Makahi Street. Visitors should be mindful not to block any private driveways. Access from Hao Street, which was once an alternative, is now private property and should not be used.
  • Timing: An average hiker can complete the full 3.8-mile loop in approximately 2 to 2.5 hours. A 3.4-mile loop can be done in about 1 hour and 39 minutes.
  • Likely Duration: This activity is best suited as a half-day outing.

Safety and cautions

  • Trail Conditions: The trail is noted for being rocky, rooty, uneven, and can become very muddy and slippery, particularly in wet conditions. Sturdy, thick-soled, and preferably waterproof hiking shoes are highly recommended.
  • Weather: As a cloud forest, expect cooler temperatures and potential rain showers, even if the coastal areas are hot and sunny. Bringing raingear is advisable.
  • Mosquitoes: Insect repellent is recommended due to the moist, forested environment.
  • Wildlife: Feral pigs and chickens inhabit the area.
  • Cultural and Land Management: The trail system is surrounded by private property, so visitors must remain on the marked trails to avoid trespassing.
  • Shared Use: The trails are multi-use, meaning mountain bikers may also be present.
  • Hunting: Hunters are known to frequent surrounding areas; wearing bright-colored clothing is suggested for visibility and safety.
  • Navigation: While some signage exists, parts of the trail may not be clearly marked. Using a map or GPS on a phone is recommended for navigation.

Editorial take

The Makaula 'O'oma Trail is an excellent choice for travelers eager to experience a unique Hawaiian cloud forest ecosystem away from typical beach and coastal activities. It particularly appeals to birdwatchers, nature photographers, and hikers who enjoy a moderately challenging, natural, and often less-crowded trail. Those seeking a cooler climate for their hike and appreciating lush, dense forest scenery over expansive ocean views will find this trail rewarding.

Conversely, visitors who prefer paved or even, dry paths, or those expecting dramatic ocean overlooks and coastal vistas, may be disappointed. Individuals with significant mobility issues or those who strongly dislike muddy, root-strewn, and uneven terrain should consider other options. Do not confuse this specific trail system with other more well-known hikes in the Kona region, such as the Captain Cook Monument Trail, which offers a different type of historical and coastal experience, or Pu'u Ku'ili Trail, which provides a shorter, summit hike.
