This route was planned by komoot.
The Black Rock and Sun-Lava Trail Loop is approximately 21.7 km (13.5 miles) long. Komoot estimates the hiking time to be around 5 hours and 38 minutes, but this can vary depending on your pace and how much time you spend enjoying the views.
The loop offers a diverse experience. The Black Rock Trail is a singletrack path winding through ponderosa pines and alongside ancient lava flows, featuring some technical sections with lava rock. In contrast, the Sun-Lava Trail is a well-maintained paved path that also traverses pine forests and lava fields. You'll encounter a rolling landscape with some mild hills, particularly a gradual uphill climb on the return leg from Benham Falls.
While the Komoot difficulty rating is 'difficult' due to its length, the individual trails have varying difficulties. The Black Rock Trail has some technical lava rock sections, and the Sun-Lava Trail involves a sustained gradual uphill on the return. For beginners or families, consider hiking shorter sections of the paved Sun-Lava Trail, which is generally easier. The full loop might be challenging for those new to hiking or with very young children.
The loop is typically accessed near the Sun Lava Trailhead, which is located close to the Lava Lands Visitor Center in Bend, Oregon. Parking is available at the visitor center.
Yes, dogs are generally allowed on this trail. However, it's crucial to keep them on a leash at all times to protect wildlife and ensure the safety of other hikers. Be mindful of the sharp lava rock sections, which can be tough on paws, and always pack out any waste.
Spring and fall are often considered the best times to hike this loop, offering pleasant temperatures and beautiful scenery. Summer can be very hot, especially on exposed lava fields, so an early start is recommended. Winter hiking is possible, but be prepared for snow and ice, particularly on the unpaved sections.
You'll experience incredible views of ancient lava flows and ponderosa pine forests. Key highlights include the Newberry Volcanic Monument: Lava Lands, where Apollo astronauts once trained. The trail also leads to Benham Falls, a beautiful spot along the Deschutes River with whitewater rapids, accessible via a short spur. From various viewpoints, you can enjoy expansive vistas of the Cascade Mountain Range, including peaks like Mount Bachelor.
Yes, the Black Rock and Sun-Lava Trail Loop is located within the Newberry National Volcanic Monument. There is typically an entrance fee required to access the monument, which can be paid at the Lava Lands Visitor Center. Passes like the America the Beautiful pass are often accepted. It's always a good idea to check the official U.S. Forest Service website for the most current fee information and any specific regulations.
Yes, the route incorporates sections of several other trails. You'll spend significant time on the Black Rock #3935 and the Sun-Lava Trail #3940. Additionally, the loop briefly passes through parts of the Deschutes River Trail and the Lava-Benham Trail.
Given the length and varied terrain, it's essential to bring plenty of water, especially during warmer months, as there are no water sources on the trail itself. Wear sturdy hiking shoes suitable for both paved and rocky surfaces. Sun protection (hat, sunscreen) is crucial due to exposed sections, and layers are recommended for changing weather. A map or GPS device is also advisable.
For a slightly easier experience on the return, consider starting your hike from the Lava Lands Visitor Center and heading towards Benham Falls first. The journey to Benham Falls on the Sun-Lava Trail is often gently downhill, meaning the sustained gradual uphill climb will be on your way back to the visitor center, which can be a good way to finish your hike.
