This is true wilderness – no signs, bridges or maintained trails. These things may have existed when the park was formed in 1973, but when I was last there in about 2000, none of that existed and the ability to use a map and compass (now GPS) was mandatory, just to access the park.
The honest truth about St Mary’s is that, despite Alpine being in its name, ⅔ is forested, peaks are few and mediocre and views are average. The attraction is in the doing – exploring a seldom-visited wilderness, solitude, and the challenge of actually walking across the middle of it. Why would you want to drive all this way to hike undeveloped trails to so-so mountains if the goal was not a traverse?
Once there, be prepared for rugged hiking. 100-foot contour lines do not show the series of 20 foot cliffs encountered in a traverse. Boulders the size of houses, granite slopes and huge blocks of broken rock make up much of the interior. This all makes for scrambling over, under, down and up very broken terrain. Snowstorms and white-outs complicate route finding. Be prepared to be tested.
Although there is a high risk of snow and cold weather, an ideal time for this hike might be in the middle of September. The park is covered in alpine larch that probably has all turned gold by the middle of the month. Most of the undergrowth will have died back after several frosts. Pick a good weather window and this difficult hike could become a possibility. Plan for a four or more day backpacking trip to see most of this park. It is a long drive from almost anywhere just to get to the access points. Getting to a good place to camp in the subalpine would take a full day.

Trail: Most traverses of St Mary’s PP begin at this trailhead, climb to the col below Mt St Mary’s and camp at Bleak Lake on the first night.
Day 1. Dewar Creek Hot Springs TH is left. The Wesley Creek trail heads right (east) – the difficult to find TH is on the side of the registration box opposite the parking area. Wade or do the difficult log crossing of Wesley Creek. Walk NE on the west side of the creek and cross a side stream at 4km. The trail disappears at an avalanche path but is where you expect it to be when you reenter the forest. If raining or dewy, be prepared to get wet here.
After walking 5kms, turn right (east) at 403-311, 5600’ where Wesley Creek comes down from the park. Cross the creek that comes down from Radiant Lake and search for a trail on the north side Wesley Creek. Head east on the trail for about 2kms until it disappears. Ascend the obvious talus slopes on the right side of the valley, then go up grass and angle left (northeast) up a spur of the main ridge. Scramble up loose scree to the col. Directly below is Bleak Lake. Scan the route past Bleak Lake carefully, try to determine the best route through the difficult terrain on tomorrows hike.
Climb Mt St Mary 2910m (9550’), only 700 feet above you to the NE and/or Nowitka Mt 2926m (9600’) to the SW along a much longer ridge. Descend to Bleak Lake and Campsite #1 on the north side of the lake.
Day 2. Explore Phyllodoce and Canning Lakes to the east, all in the alpine. Return to your campsite and continue the traverse.
Around the east corner of Bleak Lake, descend due south to the west side of Nowitka Lake. Go around the south shore and find the best descent past the lake at 458-287, go to the west of Lyallii Lake and cross Larch Meadow. Circle around to the east of the long ridge and skirt close to the bottom of it staying north of Keer Lake. Maintain your elevation to the east end of Price Lake, campsite #2. This was the location of the 1977 Kootenay Mountaineering Club Hiking camp at 451-250.
Day 3. Cross the east end of the ridge at the end of “Trinity Spire” and “Trinity Mt”. At the 7800’ level just north of Trinity Lake, drop the packs and climb the spire and mountain. Follow the SE ridge or descend by Pestle Lake and work your way back east to Trinity Lake. This is a popular place to camp or with your packs contour around the lake trending SW and then west to Mortar Lake. Campsite #3.
Day 4. Hike out the West Access Route. From the col SW of Mortar Lake, maintain elevation walking to the NW and circle west to find the top of the trail.

About admin

I would like to think of myself as a full time traveler. I have been retired since 2006 and in that time have traveled every winter for four to seven months. The months that I am "home", are often also spent on the road, hiking or kayaking. I hope to present a website that describes my travel along with my hiking and sea kayaking experiences.
