Difficulty: Challenging*
Experience: This is primarily an unmarked wilderness route across barren mountaintop terrain, with a cut access trail at each end and a few short sections of trail in between. Experience with backcountry navigation and wilderness camping is a must, and use of a gps (ideally with trail route track) is highly recommended.
Highlights: large expanses of ultramafic rock from earth’s mantle, glacier-carved fiords and canyons, lakes, waterfalls, ocean vistas, sub-arctic landscapes, rare plants, moose and caribou
Cell Service: On eastern, and sometimes northern, edge of mountains and some of the highest summits. Also along Route 440 and 450 in Humber Arm, and Route 431 in Bonne Bay South
Water Sources: All substantial streams and lakes contain potable water. Small slow-moving brooks and bog ponds should be avoided if possible.
Camping: The only official campsite along the UltramaTrex route is Trout River Campground between Stages 1 & 2 at the western end of Trout River Pond. In the Corner Brook area, tenting is possible at Prince Edward Park at the beginning of Route 440. Campsites identified on topo maps are only some of the recommended sites. Camping is permitted anywhere in the mountains, though exceptions apply within Gros Morne National Park. Contact park for details: https://parks.canada.ca/voyage-travel/hebergement-accommodation.
Transportation: A taxi/shuttle service is available to/from Woody Point at the beginning of Stage 1 (e.g. Gros Morne Transportation (https://www.facebook.com/grosmornetransportation (709-458-7296)) and Martin’s Transportation (709-453-7269)). Between Stages 2 & 3 a boat ride is required across the Bay of Islands (contact us for details) and ground transportation is required around Humber Arm. 2023 taxi rates (e.g. Star Taxi (709-634-4343)) between Cox’s Cove and Corner Brook is $75, while the rate for Corner Brook to Benoit’s Cove is $48. A pick-up (or drop-off) at the end of a gravel logging road is required at the end of Stage 4. (Contact Gros Morne Transportation (709-453-7269) for transportation between Stage 3 and Stage 4 trailheads.)
Hunting Season: As the UltramaTrex route crosses big game hunting areas, including those allocated to hunting outfitters, caution is recommended beginning in late August (for bow) and early September (for rifle). (Exact starting dates vary from year to year.) Hikers should wear a bright color and keep a safe distance from hunters and big game.
Dog Rating: Extreme and Not Recommended. Occasional talus and scree fields, some with large boulders, with very abrasive rock types
