I plan to be in the area for a bout 4 days and nights in late march. I am mainly interested in seeing natural sights and doing photography. I'll be driving a regular full-size car.
I'm starting in Jasper and my plan so far is to spend two full days leisurely driving and stopping along the Icefields Parkway (once from Jasper to Banff, once back) and then one full day in/around Banff/Lake Louise and one in/around Jasper.
I'm setting aside two days for the parkway in case of poor weather or whatnot, hoping I get good light for photos on at least one of the days.
I'm happy driving through beautiful places, so have no issues spending full days driving from sight to sight. I usually enjoy day-hiking, but given the time of year I'll probably keep it to short walks and driving.
What I really need help with is knowing where I can go in and around Jasper, Banff and Lake Louise that has open roads. I've done research but am now reading that some places I planned to visit are not accessible in March (e.g. Mt. Cavell). Great views and secluded places are what I'm after, not interested in skiing or resort-type stuff.
