hard to describe kind of, would be best to find someone to show you. I'll try my hand at giving directions though.
1. Coming from Nelson drive along the highway out to Castlegar.
2. Turn left off th highway on a side road called Blewitt Rd. (Between Bonnington Area and South Slocan Village)
3. Dive along this road until you cross the first bridge, there will be a reletively sharp turn to the left and an acess road to the right -
oh shit i have to go quickly, but i've done this much explaining. message me tomorrow and i'll finish the directions, maybe even head out there with you soon?
