Fees are collected by the Tetrahedron Outdoors Club, for cabin maintenance, fire wood delivery (which is a significant cost) and contributions to a plowing fund to keep the road clear in winter. (though officially the road is unplowed)
Fees are $10-15 per night per person (depending on if you are a member) and are the same for all four cabins (as of January 2015). You can pay fees several ways on the coast, by mail or online on the Tetrahedron Outdoor Club website. See the top of the webpage where there is a link to paypal payment site.
Access to the park is achieved by taking the Langdale ferry from Horseshoe bay, driving 30 minutes north west on Highway 101 to the town of Sehelt. From Sechelt. Drive north on east Porpoise Bay rd. for 9.5km. Turn right on Upland Drive and after 0.5km turn right onto Carmel Place to get on the Grey Creek Logging rd. The road is marked with signs and climbs up to 3100ft on the south side of Grey Creek.
This FSR is recently deactivated and as such, now has large cross ditches making low clearance vehicles inadvisable. The first 3 km of road also offer significant elevation gain. (Read: steep with big ditches) After that the road levels nicely and the drive to the parking lot is quite manageable.
Time to parking lot from UBC is 3.5-4 hours depending on wait at the ferry and how long you drive around Sechelt looking for the Tim Horton's before realizing that there isn't one.
An alternative way to reach McNair Lake Cabin is via Port Mellon Highway and the McNair Creek Road (4WD forest service road). There is no marked trail from the end of the FSR to the cabin.
You can check road and snow conditions by calling the tetrahedron outdoor club snow phone (604-740-3030), and by looking at the outdoor reports at the SunCoastCentral website. Both services are run by volunteers. As is the usual case with such voluntary efforts, they aren’t guaranteed to be up to date. In winter, chains are a good idea, particularly for the Grey Creek road.
Trail distances and times:
Distances and time are approximate, and will vary with conditions, gear, etc. Know your abilities and plan accordingly. Be aware that the distance markers in the park are not very accurate, and sometimes contradict each other. Winter routes may be shorter if lakes are frozen, but use caution when crossing.
