Iceland
Waterfalls, black sand and geothermal water, all within a day's drive of the airport.
Turquoise lakes and a mountain highway that's the point of the trip.
Banff is scenery-dense in a way photographs undersell: glacier-fed lakes in colours that look edited, a highway between Banff and Jasper that ranks among the best drives anywhere, and hiking that runs from paved lakeside strolls to serious alpine days.
The trade-off is popularity. Moraine Lake is now shuttle-only, parking fills before dawn in summer, and the accommodation in the townsite is expensive. Plan the logistics and the crowds mostly stop mattering.
Trails clear of snow by late June and the lakes reach full colour in July. Winter brings world-class skiing and frozen-lake walks.
A workable shape rather than a schedule to obey — two fixed things a day, and room to change your mind.
A rental car from Calgary is effectively required, plus a Parks Canada pass. Moraine Lake needs the shuttle; Lake Louise parking fills by 6am in July. Book shuttles the day reservations open, and fill up on fuel before the Parkway.
Splitting one vehicle and a condo in Canmore instead of a Banff hotel changes the economics completely. Assign one person to the shuttle bookings — they release on a fixed date and go in minutes.
