Red Rock Parkway is a gorgeous scenic drive in Waterton Lakes National Park with stunning views of mountains, chance of seeing the wildlife and lots of photo opportunities along the road when the wildflowers bloom during the late spring and early summer. We drove here in late May and saw tons of Arnica flowers.
PS: Make sure to only stop at one of the road side pull outs. You can usually find a rock that you can step onto if you want to take some wildflower pics, just don't step right into the wildflowers. With the right angle, you can get great shots
