But I keep in mind that you never needed oxygen (at significantly higher altitudes than those I'll ever be exposed to).
Before venturing in exotic locations, I'll probably try Denver
IF you go to Denver (about 5300 ft/1600m), try driving up to the top of Pikes Peak and see how you feel after 15-20 minutes up there. If the traffic isn't too bad, and you're OK, try walking down the road for 20-30 minutes then walking back up and see how you feel. If anything it'll be a good workout.
As for what others say above about traveling in the southern Asia area, I'd be quite wary of venturing there right now. I've seen reports on climbing sites of groups in the Karakorum region of Pakistan needing to keep a low profile, some suggesting military escort, and Americans are really encouraged not to go there right now (not sure about Canadians, check with the Foreign Ministry). China might be the same as relations seem to be deteriorating with the COVID pandemic, the South China Sea dust-up, and now the Taiwan situation.
