With temperatures dropping like crazy, most of us are finally admitting that fall has arrived, putting our flip-flops in the back of the closet until next year (except for those of us who live in tropical climates year-round). Sadly, we’re also saying goodbye to days of fun in the sun, barbecuing and hanging out by the pool.

Colder weather means we’re less likely to want to venture out with friends and instead post up on the couch with a cup of coffee and a some quality TV shows. However, there are some exciting things to do in the fall, both indoors and outdoors, that are great for bonding with friends and roommates and won’t burn a hole in your wallet. Here are some of our top picks:

Make Caramel Apples

The Food Network has a mean caramel apple recipe and the ingredients are all reasonably priced. Some you may already have in your kitchen, like apples and butter. In total, you’ll spend about 40 minutes working on this (maybe a few more). The best part? Adding whatever toppings you want. Our suggestions: Oreos and crushed Reese’s cups.

Head Out on a Ghost Tour

Halloween will be over before we know it, and while pumpkin patches and corn mazes disappear, ghost tours are usually available year-round. A quick Google search will have you connected with a tour in your city. Tickets usually range anywhere between $15 and $30 depending on your city and sometimes offer group discounts, so gather up everyone you know!

Have a Fun-Filled Night In

This is probably the most appealing option considering all activity is indoors (making caramel apples does involve a trip to the grocery store). For a night in with friends, host a mini-dinner party where everyone brings an appetizer and perhaps a bottle of wine or another beverage. You’d be surprised how creative people will get (think homemade spinach & artichoke dip or stuffed peppers). It’s fun to see what friends come up with and everyone wins because there’s a huge variety of options with a low cost.

Hit Up a Local Museum

This may sound corny, but some museums have really cool seasonal exhibits. Because entry fees are so low and sometimes nonexistent, there isn’t always a lot of money left for museums to advertise, so you may have to do some sleuthing. For example, the Cincinnati Art Museum currently has an Art Deco exhibit (running through January 2012) and the Museum of Modern Art in New York City has a New Photography exhibit (also running through January 2012) with some awesome pieces.
