Some hobbies require a second income just to afford them. Golf, skiing, photography with professional gear — those can run into the thousands before you've even broken a sweat. But the best hobbies? They're often the ones that cost very little, or nothing at all, and leave you richer in ways that have nothing to do with your bank balance.

Here are a few frugal hobbies that prove you don't need a trust fund to have fun:

Walking: It's free, healthy and available anywhere — sidewalks, trails or, if the weather's bad, the aisles of your local discount store. Shoes are recommended, but otherwise, zero cost. Bonus: Walking is a perfect time to think, pray or just practice ignoring robocalls.

Gardening: No, not the kind where you spend $500 on a raised bed kit. Frugal gardening starts with seeds saved from last night's tomato, cuttings from a neighbor's mint plant, or even a few herbs on your windowsill. The reward is fresh food, fresh air and bragging rights when you serve salad you grew yourself.

Cooking: A $2 bag of beans can turn into chili that feeds six. That's entertainment and dinner in one pot. Try challenging yourself to cook from what's already in your pantry — half hobby, half game show.

Reading: Bookstores are fun, but libraries are magical. Books, e-books, audiobooks, even puzzles and movies — all for free. Many libraries also host classes and clubs, making reading a hobby that comes with friends attached.

Volunteering: Animal shelters need dog walkers. Food pantries need shelf stockers. Schools welcome tutors. Volunteering doesn't cost a cent, and it might be the most rewarding "hobby" of all.

Writing: A notebook and a pen are all you need. Journaling lowers stress, sparks creativity, and provides a record of your life. Science even says gratitude journaling boosts happiness — no pricey membership required.

Thrift hunting: Skip the mall and head to the thrift store. The fun is in the hunt: a quirky mug, a vintage record or the perfect sweater for $3. Garage sales, flea markets and swap groups all scratch the same treasure-seeking itch.

Puzzles and games: Crossword puzzles, jigsaws or a deck of cards can keep you entertained for hours. Swap puzzles with friends to keep it fresh. Frugal, social and brain-sharpening — what's not to love?

Music: New instruments can cost a fortune, but secondhand shops and online swaps are full of guitars, keyboards and ukuleles. Add free YouTube lessons, and you can be strumming your way to happiness without strumming your budget. And if you're more into singing than strumming — good news. The voice lessons you give yourself in the shower are still free.

Crafting: Crafting doesn't have to involve craft-store sprees. Start with what you already have: jars, fabric scraps or cardboard. Turn junk into decor, gifts or at least something Pinterest-worthy.

Photography: Forget $2,000 lenses. The camera on your phone is good enough to turn ordinary walks into scavenger hunts for beauty. A "photo-a-day" challenge costs nothing and makes you notice details you'd otherwise miss.

Outdoors: Hiking, birdwatching or just sitting in the park with a thermos of coffee — all count as hobbies. The fresh air is free, the entertainment value is high, and no ticket prices are involved.

Productive hobbies: Some of the best hobbies are the ones that also get things done. Decluttering a closet, painting a room, or repurposing an old ladder into a bookshelf can scratch your creative itch while saving money or improving your home. It's the kind of hobby where you end up with both a cleaner house and a cleaner conscience.

The truth is, hobbies don't have to be expensive to be worthwhile. The best ones enrich your days, not your credit card bill. They keep your mind engaged, your body moving, or your heart connected — all while costing little more than time.

So before you decide that hobbies are a luxury you can't afford, remember this: Some of life's richest pastimes are the ones that don't come with a receipt.
