First stop: the touristy Athabasca Falls. Paved short walk to the viewing platforms of the falls on both ends of the chute2nd stop: Sunwapta Falls. A short walk downhill to see the waterfall. Not paved.
Both are not worth your time. The scenery of the highway is much better, especially near Columbia Icefield.
First hike of today: Wilcox Pass (8Km RT 335m). The trailhead parking was full. Continue on the road, you'll arrive at Wilcox Campground. We parked along the road. The trail starts in the woods, but soon (less than an hour), you break out on to alpine meadows. I have to sit in one of these typical park chairs. 
Continue on, fairly easy grade, you'll reach the main trail junction mark (~2.5 mile in). However, Columbia Icefield disappears behind small bumps on this plateau. Turn left 1.3Km to the furthest west bump. Had lunch here, soaking the front seat view of Athabasca Glacier. It's immense. 
On the way back, I continued north on Wilcox Pass trail for about 20-30 minutes. It's flat. Cross a couple of tiny streams. A few small tarns. They probably will all dry up by end of August. Very few people. I was hoping to see Bighorn sheep, but saw none. Quite some flowers left. I was told the peak boom was 2 weeks ago. I enjoyed the walk. Ideally you can walk one way and reach the north trailhead on Icefield Parkway (Tangled Falls 14Km total?).
2nd hike of the day: Parker Ridge (5.4Km RT, 250m). A huge parking lot only a few miles south of Wilcox Pass. The sign at the TH says 2.4Km. So short that Vinit agreed to do this 2nd hike. Once we reach the ridge, there're trails going all 4 directions. This is just the start of exploration. Already jaw-dropping splendor. 
I took the right trail going up. At the very top, I saw 2 rock circles (are you allowed to camp here?). People sit inside to avoid some of the wind. I continued the trail right, but still cannot see the full view of the next glacier. After returning to the top, I hiked down left closer to Saskatchewan Glacier, and the green valley it has carved, light blue lake and braided creek. Another short hike with amazing view. Vinit had trouble with his knee coming down. I gave him one of my knee braces. Still we were very slow.
After a stop at Waterfowl Lake, we went to Peyto Lake for sunset. It was still early, so we cooked and ate dinner. Quite some yellow columbine here. Around 8pm, we parked in the upper parking lot, and walked to the viewing deck to wait for the sun to set.Checked into HI Lake Louise Alpine Center ~11pm. Male dorm and female dorm are in different buildings. Each has a kitchen in the basement. All needs a card key to enter. Wifi is slow (even at midnight). The night clerk suggested sunrise at Moraine Lake, because the parking lot is filled up early. Once full, the road will be blocked. We would need to arrive by 6am to ensure a parking spot. I later found out that there's a bus going to Moraine Lake for $25/RT ($15/oneway, every 1.5 hours). But the earliest is at 9am, last return at 6pm. Not possible for sunrise or sunset. There's also a bus going to Lake Louise too.
