This trail is considered strenuous or difficult due to its length and significant elevation changes. It involves two major climbs, including a 950-foot ascent to Hazard Peak. It's not recommended for beginners or those unaccustomed to long, challenging hikes.
The terrain is diverse, featuring well-maintained dirt paths, steep sections with switchbacks, and more gradual rolling terrain. You'll encounter significant elevation changes, including a substantial climb to Hazard Peak and descents into canyons. The Islay Creek portion is a wider dirt road.
The trail offers spectacular and varied scenery. A major highlight is the summit of Hazard Peak, which provides panoramic 360-degree views of the Pacific Ocean, Morro Rock, Morro Bay, and inland over the Irish Hills. You'll also experience secluded canyon views, sycamore-covered areas, and potentially a small waterfall along Islay Creek Trail, plus a dilapidated barn.
Hikers generally take about 4 hours and 30 minutes to complete the 9.2-mile loop. However, individual times can vary based on fitness level, pace, and how often you stop to enjoy the views.
Yes, the route incorporates sections of several other trails within Montaña de Oro State Park. You will hike along parts of the Hazard Peak Trail, Islay Creek Road, and Barranca Trail, among others.
Many hikers prefer to tackle the steeper climb to Hazard Peak early in the hike, often by heading clockwise. This allows you to get the most challenging ascent out of the way and enjoy the expansive ocean views as you climb, before descending into the more secluded Islay Creek Canyon.
Given its length and difficulty, it's essential to bring plenty of water, snacks, sun protection (hat, sunscreen), and sturdy hiking shoes. Layers of clothing are also recommended as coastal weather can change quickly. A map or GPS device is advisable for navigation.
