Connect With Nature
One of the best and most effective way to relieve one's stress is definitely connecting with nature. Being surrounded by trees, and hear the chirping of the birds could make one forget about the hustle and bustle of life. It may not be permanent but, at least, in that temporary moment, your mind and body get to recover.
One of the places I went that I consider to be memorable is at the Mountain of Kalugong located in Baguio City, Philippines. You'll get a good view of the tall pine trees here, sit by the rock formations where you can overlook La Trinidad, Benguet, and feel the peace of nature. If you are quite lucky, you can also experience its foggy morning or foggy afternoon while enjoying your hot coffee in one of the cafeterias there.
Reaching this place is not that hard since either you can bring your car/bicycle, or commute via cab/taxi, or you also have the option to walk. If you go by car/bicycle, you would have to drive on a steep one-way road but once you reach the end of it, you would only need to walk up the trail for less than 5 minutes and you'll find yourself on the entrance.
So if you wish to travel to the Philippines, I suggest that you should have some time to drop by in Baguio. You won't just be enjoying several nature adventures but you could also go and visit the Strawberry Farm and pick some strawberries yourself. You can also visit several sites that shows off the culture of the Cordillerans. It won't be a waste of time and money, that is for sure.
