About This Trail

Tree Cast Trail is a unique route through the rugged volcanic landscape of the Nass Valley, crossing rough lava-rock terrain formed during the region's historic volcanic eruption. The trail includes long sections of exposed lava slabs, loose volcanic rock, and uneven surfaces, making sturdy footwear with thick, supportive soles highly recommended.

The main attraction is the remarkable Tree Cast, a natural volcanic formation created during the eruption. Flowing lava knocked down and surrounded a tree, forming a cast around its trunk as the molten rock cooled. Over time, the tree itself completely decomposed, leaving behind a long, cylindrical cavity preserved within the hardened lava. The formation provides a fascinating glimpse into how the volcanic eruption shaped the landscape and created unusual geological features that can still be seen today.

The rough terrain and unique geology make Tree Cast Trail an excellent destination for visitors interested in exploring the volcanic history and natural features of the Nass Valley.

Getting There

Directions

Tree Cast Trail is located within the Nass Valley on Nisg̱a’a Lands in northwestern British Columbia. From Terrace, travel north along Highway 113 (Nisg̱a’a Highway) toward the Nass Valley. Continue toward the Nisg̱a’a lava fields and follow local signs for the designated lava-field attractions and trails.

Follow the signed access route toward the Tree Cast area. From the designated parking area, continue on foot along the established route toward the lava fields and the Tree Cast formation. Because access roads and trail conditions may vary depending on the season, follow local signage and check current Nisg̱a’a visitor information before travelling.

Parking

Parking is available near the designated access area for Tree Cast Trail. Facilities in this remote volcanic landscape may be basic, and parking capacity can be limited.

Park only in designated areas and keep access roads and gates clear. Do not drive onto the lava fields or park directly on fragile volcanic terrain. Be considerate of other visitors and local community access.

Safety & Preparation

  • Rugged volcanic terrain: Expect uneven lava rock, exposed slabs, loose rocks, cracks, and irregular surfaces.
  • Wear sturdy footwear: Thick-soled hiking boots or shoes with good grip are strongly recommended. Lightweight footwear may provide inadequate protection on the rough lava.
  • Watch your footing: Loose volcanic rock can shift underfoot, while uneven slabs and cavities can create trip and fall hazards.
  • Stay on established routes: Avoid climbing on or disturbing geological formations, including the Tree Cast itself.
  • Tree Cast safety: The cylindrical tree cast is a fragile geological feature. Do not enter, climb into, or damage the formation.
  • Weather: Rain can make the lava surfaces slippery, while hot and sunny conditions can increase dehydration risk. Carry sufficient water and dress appropriately.
  • Limited services: The lava fields are in a relatively remote area with limited facilities. Bring food, water, and other essentials with you.
  • Cell service: Mobile coverage may be unreliable. Download maps and important information before leaving areas with reliable reception.
  • Wildlife: The surrounding landscape is natural habitat. Maintain a safe distance from wildlife and never feed animals.
  • Respect Nisg̱a’a Lands: Follow posted rules and local guidance, and treat the volcanic landscape and surrounding cultural sites with respect.
  • Leave no trace: Do not remove volcanic rocks, plants, or other natural materials. Pack out all garbage.
  • Emergency preparedness: Due to the rough terrain and remote setting, carry a basic first-aid kit and let someone know your planned route before setting out.
