Garibaldi Provincial Park
Panorama Ridge above Garibaldi Lake is the best hike in the region (18 miles return, 5000ft). Late September had some snow to cross on the ridge, but there were no flies, which can be a problem here during the summer months. Black Tusk can also be climbed from the campground in the meadows.
The trail to Wedgemount Lake is straight uphill the entire way, feels short without any switchbacks (9 miles return, 4000ft). The extra hike to the glacier on the east side of the lake is recommended.
There is no trail to Keyhole Falls and a full day must be dedicated to reaching it. The directions I used are here. I chose to hike around the upper canyon for an elevated view of the falls (51km pulloff). Hiking up the river would give the closest view, the gravel slopes on the upper canyon prevent a direct view from above.
The middle and upper lakes are the most beautiful and easy to reach on a wide trail (7 miles return, 1200ft). Camping is allowed at the Upper Lake.
Brandywine is the other must see waterfall. There is an unofficial trail to the bottom of the falls that starts at the end of the paved walkway.
Place Creek Falls
Place Creek Falls is not far from the road although the trailhead is not marked (2 miles return, 700ft). I used the directions in Don't Waste Your Time, which involved crossing through private property. There could be a better way since the book was published 20 years ago.
