No doubt about it: Lake O'Hara is our most favourite place ("Happy Place") on this planet.
We have been very fortunate and been able to make a trip here at least once every year since 2002 (getting seats on the bus into O'Hara can be a bit of a hassle).
Often there is too much snow on the alpine traverse and we have to "make do" with the Lake Oesa and Opabin trails. The highline is definitely our favourite trail though!
