As long as you clear them it doesn't matter how high. Safety depends on

I prefer a bit more air underneath me than that considering the anemic
climb rate of my aircraft at altitude... When I flew to the Grand Canyon a
few years back, I encountered 2000 fpm updrafts... That was *great*... I
talked with some of the charter pilots around there about it and soon
learned that you can also encounter 2000 fpm downdrafts... That would
*not* be great...
