This sounds like a wonderful idea and so peaceful and good for your soul.
get your backpack and a tent. Pack a weeks worth of food, and something to do, like bring a harmonica or a paperback of war and peace. Drive your car to a trailhead in the woods, hike to the top of a big mountain, and set up camp where there is a view from the hilltop but far from the trail so other hikers will not see you. Notice where the streams/springs are for water supply on your hike up.
Then set up shop there for a week. Explore. Watch the sunset. Drink a hot cup of cocoa as the sun rises.
At some point, the mountain will talk to you. I suggest you listen
