"Bushwhacking" refers to traveling or navigating through wild, uncultivated areas, often off-trail, by pushing through dense vegetation like bushes and trees. It's essentially hiking or traveling where there is no established path, requiring you to forge your own way through the undergrowth.

Went out hiking in Mt. Douglas last Friday morning.
With 225m elevation, Mt. Doug is more a hill than a mountain, but it has some big old-growth Douglas-fir trees, and plenty of second-growth forests. The ocean and (real) mountain views at the top is breathtaking.
Half way up, a big yellow dog jumped out from the woods next to the trail, then a young couple followed out. They both smiled when I was petting the dog, and the gentleman explained: "We were lost on the hill and bushwhacked our way down."
Hope you all have some nice outdoor times today.
