I realize the mountaintop experience is the quintessential stereotype of divine moments, but there's a reason for that. Just look at the view in this photo - breathtaking, awe-inspiring, deeply moving.
Here in central Arkansas we have a popular hiking hill called Pinnacle Mountain. It's a little over a mile from base to summit, roundtrip, which makes it easy to set aside a few hours one morning or afternoon to enjoy.
One could incorporate the prayer model from the labyrinth walking up the hill (releasing), sitting at the top and taking in the expanse (receiving), and walking back down (integrating). Plus, all those endorphins you'll release should aid in prolonging that feeling of union, of being anxious for nothing, of resting in God's peace.
