We called this one Porcupine's Playground as we've seen a number of porcupines while up on Nosehill - they love to climb the shrubs and larger bushes to eat the buds and new growth.
The smaller trail is another family favourite, to get in range of the cache. I've been coming to this dog-walking trail for over 20 years, as it tends to be a lot less busy than the other parts of Nosehill Park. Head to the top and then over, before beginning your search.
We usually park on MacEean Glen Drive NW. Look for the fire hydrant on the north side of the street, and the trail starts across the street - look for the black electrical tape on the wire fence.
Enjoy!
