Hey Dorf - I'll try to add my views on some of the others you didn't mention. I'll add more as I get time.
Kintla Lake, Head (KIN)
Similar to Bowman Lake, Head in many respects. A large campground frequently used by kayakers. Nice woodsy feel but expect a good amount of company.
Upper Kintla Lake (UPK)
A very nice camp situated under large lodgepole and larch pine trees. Fantastic views of Kinnerly Peak from the campground "beach". The sites are a bit close together though.
Boulder Pass (BOU)
Spectacular high alpine camp located on the edge of an exposed lava flow. While views are somewhat blocked from camp, within just a few minutes from camp you can see Agassiz Glacier, Kinnerly Peak, Kintla Peak, Mt Peabody, Boulder Peak, Boulder Pass, and the Akamina Ridge. Not to mention a 20 minunte walk up and over Boulder Pass reveals the Hole-in-the-Wall/Browns Pass area with more spectacular views including Thunderbird Mountain. However, the camps are situated close to Gardner Point and falling rock can be an issue.
Hole-in-the-Wall (HOL)
No description required, just go there. Can be a busy camp with 5 sites.
Hawksbill (HAW)
Very open camp with a great view of the somewhat less than exciting Hawksbill rock formation. You do get a great view to the long ridge to the north that includes Chapman Peak and Shaheeya Peak. The best thing about the camp is that Lake Francis is only .2 miles away and is a great place to spend most of you down time.
Lake Janet (JAN)
Nice views to the south of the Porcupine Ridge, but that's about it. The camp is actually not on the lake, but about .2 mile east of it. Bugs can be a problem here and Lake Janet slowly dries up as the summer goes along leaving about 50% of it as a less than impressive mud flat instead of a lake.
Waterton River (WAT)
Again bugs can be a problem, but this camp offers in-your-face views of Mt Cleveland, the tallest peak in the park. Another thing to keep in mind is that the horse ford for the Boulder Pass trail runs directly into camp (if hiking from the east and staying in the camp, you can cut about 1/4 mile off your hike and by following the horse ford and fording the river instead of going across the suspension bridge. Recommended only when the water level is low). From the perspective of camp, the ford appears to be the water access. Because of this, if staying in the camp, you might want to consider traveling up the river a ways to get water.
