This is an interesting, beautiful hike. There are many possibilities to go onto other short hikes such as Goat mountain, Little Goat mountain, and Dam mountain. If you have the chance to get picked up from a different location from where you started (or take public transit), then you can finish off your hike by going down into Hanes valley and out to the Lynn Headwaters Regional Park (the trail can also be started from Lynn park, but is about an additional 11km of flat trekking, and an extra. The view from the top is magnificent and in every direction. You get to see the Camel, Goat mountain and various other peaks and of ccourse the city of Vancouver. This trail is a great workout and a moderate dayhike if coming up to Grouse on the skyride, but if the Grouse Grind had been done just before, then altogether this would be a strenuous trail with a lot of elevation gain.
There are two possible trailheads where you can start the hike from. The short approach is from the grouse mountain gondola via the upper part of the Hanes Valley Trail to Crown Pass. The long approach is from Lynn Valley via the Hanes Valley Trail to Crown Pass. Starting the hike from Lynn Valley and returning via grouse mountain make a nice loop.

(This info is for those who take the skyride up to Grouse mountain and start the hike from there.)
Head north on Capilano Road to the Grouse Mountain Skyride. The Crown Mountain trail starts to the east at the top of the Skyride past the bear and wolf habitats at the top of Grouse mountain. The Grouse Grind starts just to the right of the Skyride and comes out by the Grouse mountain restaurants.
Head out of the Skyride towards where the Grouse Peak chairlift used to be and then stay left on the old service road. After a bit, you will reach the entrance to the Lynn Headwaters Nation Park, where is is asked to leave your contact information before entering the park. Once that is done, follow the well marked trail descending to a small pass and then heading up to skirt Dam Mountain and over to Little Goat mountain. You also have the option to go up to Goat Mountain before descending down to Crown pass. This is just a little bit of extra hiking, but well worthwhile and a great spot for a lunch break. From here the trail gets a bit rougher and slippery as you descend down to Crown Pass. At the lowest part of the pass, you will come to an intersection, you will need to take the left which will lead you to the top of Crown Mountain, as the right will take you down to Lynn Park through Hanes Valley which is about 12km from here. For Crown it is uphill from here, 421 metres to be exact as you just lost about 300 meters after that descent. The trail is rooty and can be damp and many bugs on a real warm day but persevere as soon you will be at the top. Watch your footing as the trail may be a bit slippery from remnant snow melting in the trees above. The trail ends at a rocky ridge, but an easy scramble will lead you to the top. Have a nice break here and enjoy the views because you summited a neat and moderately challenging peak away from the masses.
