The boardwalk through the bog is great, but if you have little kids, look out for people on bikes. The microclimates are pretty cool as it moves from wet bog to drier conifer forest. The biology/geology of the big is also cool - read about it before your walk. Don't trust Google Maps to bring you to the right place, it put us about 2km down the road in a residential area. Another downside is that you never really get away from the highway noise. The day we went, a Saturday, there were barely any people on the bog itself allergic there were plenty of folks out walking their dogs on the side trails.
