Active vacations are often the most relaxing of all. But Wait! It's all in defining what an active vacation is. We don't expect you to take up jogging, backpacking, or hang gliding. we ask the sedentary（爱坐的）vacationers to spend two to four hours a day doing things, such as walking the city streets, exploring a nature preserve, or taking a leisurely rowboat ride.

These kinds of activities aren't just good for your physical health. They improve your mental health, even your spiritual health. And they make vacations memorable and worthwhile. Here are some fresh ideas for active and healthy vacation.

Make the morning your activity time. At that time it is most likely that the weather will be friendlier, your energy level higher, and your schedule emptier than later in the day.

Have a walk at dawn or dusk. Such activity is called rejuvenation（恢复活力）. Try to make this a daily routine of life away from home, and you will guarantee yourself both physical and spiritual youth.

Get into the water as much as you can. Don't allow yourself to spend your entire time sitting in front of the water. Whether it is the ocean, a swimming pool, or a tree-lined lake, make sure you get into the water for swimming or games or even walking. Merely standing in waist-high water is a good workout, thanks to the action of the water. And you'll feel so much more alive!

Choose a cruise for your trip. It's amazing how active you can be being stuck on a boat in the middle of the Atlantic. Most cruise ships offer numerous options for seaworthy exercise. During your sea and land trips you can burn calories as you swim, hike, dive, and horseback ride.

Get out of the car every two hours. Many of us spend a large part of our vacations on the road, either getting to and from our destinations, or using the car for sightseeing. But no matter how beautiful the scenery is, great and memorable vacations don't happen in a car seat. Don't wait for tiredness or nature's call to get you to pull over. Frequently get out and stretch, walk, picnic, shop, visit, and have fun. It's important for your health and energy, and it makes traveling a lot more active and interesting.
