Squamish River FSR - Ashlu Main & A-600

Page 2 of 2

Distance From Vancouver:
About 99 km - 65 km via Highway 99 North to Squamish Adventure Centre, then keep driving straight on Highway 99 and turn left onto Squamish Valley Road 9.6 km later, then drive for 23 km to Squamish River FSR, and turn left onto Ashlu Main 1.2 km after that.

Liked: Decent road surface until the end of 2wd road for both Ashlu Main and A-600 branch road, several good natural views, dam view (Ashlu Main), shadow in the forest while walking on both Ashlu Main and A-600.  

Of note: Not too many mosquitoes but numerous annoying flies, very few views while walking on Ashlu Main for several hours past the dam (where the 2wd road ends).

19. At the 4.0 km mark, there is a good view of Ashlu River.

20. Also at this spot, there is this very interesting device to warn kayakers of rapidly rising waters due to the discharge from a dam upstream.

21. At 6.7 km, there is an unmarked road split. To the right is Ashlu Main. To the left/straight is A-600 branch road. We went straight/left here to explore A-600.

22. A-600 2wd road ends at 8.8 km. The road narrows and becomes very rough. There is a turnoff to the dam there too, and the dam itself is easy to see, but the best view is from Ashlu Main. Here is the narrowing of A-600.

23. Looking the other way. Straight ahead is where we drove from, and to the left is the turnoff to the dam.

24. And so we parked right here and started walking down the narrow part of A-600. In about ten minutes, this busted tractor would stop everything except bicycles and walkers.

25. And, about ten minutes later, A-600 ends where several badly trashed buildings are standing in a picturesque setting.

26. According to the Backroad Mapbook, Osprey Mines used to be located in this area. We did not find any mines here.


27. But sure found lots of bullet holes.

28. No more dining in here.

29. After visiting A-600, we returned to the road split seen in photo #22, and turned onto Ashlu Main. Very soon we encountered a mini quarry by the roadside.

30. Nice stones.

31. A few minutes later, you are crossing a small river. Good views from the bridge.

32. Less than 2 km after the split with A-600, Ashlu Main 2wd road ends with a view of a dam. On the other side of the river you see a road which very shortly comes to a point seen in photo #24.

33. And so we parked right here, and started walking on Ashlu Main. The road became narrow and rough in several areas, though mostly it was in decent shape, probably because very few people drive here.

34. It is a pleasant walk on a hot day due to all the shade. The only problem - you do not see much. Just the trees. A bicycle or an ATV would be very good here.

35. The first decent view comes more than an hour into the walk - there is a small bridge and a fairly impressive waterfall there. Be very careful when checking out the creek on the other side of the bridge - the small log serving to keep you from falling into that fast flowing stone-filled creek could be slippery from the waterfall's moisture, and, if you decide to step on that log to get a better photo of the creek below, it might not end well.

36. And then we walked for another 45 minutes with just glimpses of mountains here and there, but not much else. The reason for such persistent walking was because a guy we encountered on A-600 earlier in the day said that some days ago he drove an ATV on Ashlu Main all the way to a washed out bridge, and saw some decent views. However, it was getting late in the day, and it was time to have a break and head back. Just when we were going to return while seen nothing impressive, there was a split on the road. As the river was heard on the left, this is where we turned.

37. Several minutes later, we encountered a badly worn-out bridge. Logging trucks haven't been here in decades, it seems.

38. The worst part about having a meal break on this bridge were the flies, which decided to have us as THEIR meal break. The best part was this view, which made the whole walking trip (somewhat) worthwhile.

In conclusion, Ashlu Main is not the most impressive of all the other major Squamish River Forest Service Roads, but it is a fairly smooth road, it has its attractions, and having a free campsite by Squamish River does not hurt either.
