Spent a few hours in Happy Valley, just past the Cathedral Reserve in Mount Wilson, a few hours drive out of Sydney, NSW, in the Blue Mountains. There's a sign on the road marking the start of the trail to both Happy Valley and Cathedral Creek. Cathedral Creek is only 300m and a fairly easy walk, though steep in places. The trail down to Happy Valley is hard and very steep, but can still be covered on your feet....no ropes or need to climb (mostly).
