Check road status before you leave

Marion Creek road is currently deactivated and has several water bars. It requires at least an all-wheel drive with good clearance or a 4 x 4 vehicle to access the trailhead. The Alberni Valley Outdoor Club might be able to provide current information on the road: https://albernivalleyoutdoorclub.wordpress.com/


From Port Alberni on Vancouver Island

Set your odometer in Port Alberni at the T-junction by the river at the foot of Johnston Road. Turn right on Highway 4 (the Pacific Rim Highway) and follow it west from Port Alberni past Sproat Lake and over Sutton Pass. The distance from Johnston Road to the Marion Creek turn off is 56 km – approximately 6km beyond the highest point on Sutton Pass. Marion Main is on the left just after a sharp bend in the road and directly opposite a “Slow” sign. Follow Marion Main for approximately 6.3 km to the Cobalt Lake trailhead.


Trail Description

Cobalt Lake is located 800 m SSW and 400 m below the summit of 5040 Peak. The trail head is on the left side of the road just beyond a small creek and should be marked by a ribbon. The trail sets out through a clear cut before entering an old growth forest and starting to rise fairly steeply. It parallels the creek for part of the way and opens out into series of rock bluffs just below the lake. Although the trail is not marked, it is relatively easy to follow until it reaches Cobalt Lake (approximately 1.5 – 2 hours hiking time).

From Cobalt Lake a less well developed “route” leaves the northwest corner of the lake and ascends through heather to just below the summit. Although there is no formal trail to the summit, most people approach it from the saddle on the southeast side of the mountain.


5040 Peak

This mountain derives its unimaginative name from its summit elevation of 5040 feet. Strong hikers are known to ‘do’ 5040 Peak as a day trip from their vehicle. However, the elevation difference from the trail head to the summit is more than 900 metres and it is recommended to carry camping equipment to stay one or two nights at or near Cobalt Lake. This way one can take the time to enjoy the mountain flowers and the spectacular scenery this hike offers. Cobalt Lake is located on the SW side of the mountain, just above tree line at 1,130 metres elevation. But flora highlights are distributed on all sides of the mountain and make more exploration time desirable.


Getting around on this mountain requires reasonable fitness, alpine hiking skills and experience with navigating mountainous terrain during poor visibility, as the clouds are quick to move in. There are no well established trails beyond Cobalt Lake. 


Six ridges radiate out from this broad peak, the most prominent easterly one connects it all the way to the 6 km distant Nahmint Mountain. Two other ridges, one to the south-east and one to the north, are of interest to flora enthusiasts due to their limestone occurrences. The remainder of the mountain and its ridges are made up of non-calcareous volcanic and minor intrusive rocks.


The winter snow pack on 5040 Peak is very high in most years, except in extreme El-Ninjo years. As a result, the emergence of alpine vegetation is often very late in the summer, with August and even September being the best months to see the plants in bloom.


Floral hotspots are distributed all around this mountain, not only on the special limestone geology, but also on the more common volcanic rocks. Starting on scree slopes above Cobalt Lake and along many small streams and meltwater seeps all around this peak, pink and yellow monkeyflowers (Erythranthe lewisii and E. caespitosa) are more abundant than on most other mountains. On the limestones several species occur that are otherwise not known to occur on Vancouver Island or are primarily found on limestone, such as arctic willow (Salix arctica), male fern (Dryopteris filix-mas), corrupt spleenwort (Asplenium abulterinum), mountain death camas (Anticlea elegans) and American sawwort (Saussurea americana). Generally, alpine plants descend to lower elevations on the more barren east- and north-facing slopes of 5040 Peak. Eight species rare-listed for the province have so far been found around 5040 Peak, among them smooth douglasia (Douglasia laevigata), Olympic mountain aster (Eucephalus paucicapitatus), and corrupt spleenwort (Asplenium adulterinum).
