Great Activities for Nature Lovers
Hiking
One of the easiest and most accessible ways to get close to nature is by setting out on a good old fashioned hike.Hiking generally doesn't require any fancy equipment or special skills, just a piece of map and a thirst for adventure.This activity can be as relaxing as you make it.
Backcountry Camping
Why limit yourself to just a day hike when you can have a full weekend (or longer) adventure？Backcountry camping involves packing your tent, sleeping gear, food, and water on your back to set up camp in a remote location.If you're an experienced hiker and camper, this is an excellent way to test your survival skills and explore the wilderness.
Mountain and Road Biking
Unlike long hikes through the woods, biking allows you to cover more ground and travel farther in nature.Mountain biking typically involves riding up and down steep slopes, between trees, and over rocks.If this sounds too intense or your tires aren't suited for rugged terrain, consider taking a road bike on paved trails through forest preserves or along country roads.
Gardening
Contrary to popular belief, you don't have to travel beyond your own backyard to experience the beauty of nature every day.If your personality is less adventurous or your mobility restricted, consider planting a garden to grow your own vegetables, fruits, herbs, or flowers.There's something truly satisfying about mixing up a salad with fresh ingredients you grew yourself.One of the best parts about spending time in nature is that it doesn't have to break your budget and anyone can do it.
