summer is upon us. Warm, sunny days stretch into golden evenings, and there's more time than ever to try something you've never done before. Exploring new activities and shaking up your routine can give you something to look forward to; it can also do wonders for your health and creativity. Take a look at these ideas and put one or two on your calendar today.

Try Ziplining Back in 2012, 101-year-old Dorothy Custer celebrated her 101st birthday by ziplining over the Snake River in Twin Falls, Idaho; if she could do it, you can too! Find zipline tours all over the world and in most U.S. states where you can go for the glide in varied locales that range from a Costa Rican rainforest to an underground limestone mine in Kentucky.

Attend A Music Festival From classic rock to folk to jazz, there's something for everyone at the many music festivals taking place all over the country (and the world) in summer 2016. Visit MusicFestivalWizard.com to find a venue near you.

Go Wine Tasting Even if you don't live in wine country, there are plenty of ways to get your sip on. Local restaurants often hold tastings, which is a great way to try new wines and expand your palate. Become an amateur oenophile by taking a local continuing education class where you'll get to taste some great wines, learn how they're made, and how to pair them with food. Or host an intimate wine party yourself; just provide the hors d'oeuvres and assign a different wine varietal for each guest to bring.

Do A Mud Run Get down and dirty with one of these messy races. Recruit your friends to create a team and train together ahead of time (or just wing it for fun). Talk about photo ops! Find races at MudRunGuide.com.
