Relaxing and enjoyable outdoor activity

Do you always plan an outdoor activity for your family where all of you can relax and enjoy? My family like to go fishing during weekends in a nearby lake in our place and always bring picnic mat and foods for us to enjoy while we are fishing. But me and my husband alone always like to go hiking because we are both nature lover. What are some of your outdoor adventures? Where are you going and why do you like doing that kind of activity?
