I just moved to a new city and want to make some friends. I'm open to most things, but I especially love outdoor activities. Please don't suggest anything involving church groups as I am not religious. Generate a list of five ideas and make sure that you describe each one so that I can get a sense of whether or not I'd be open to trying it. 
Here are five things you can try to help you make friends in a new city. These ideas take into account your openness to most things, your love of outdoor activities, and the fact that you aren't religious. Each idea includes a description so that you can better understand whether or not you'd be open to it: 

1. Sports Leagues. Given your interest in being active outdoors, consider joining a recreational sports league. Search online or ask around at your workplace or gym to see what leagues are available to join. Pick a sport you think you might enjoy and choose a league that is appropriate for your anticipated skill level. Joining a sports league is a great way to get outside, engage in friendly competition, and most importantly, meet new people. 
2. Volunteering. Pretty much every city should have volunteer organizations where you can donate your time. Volunteering is not only a great way to give back and help those in need, but it's also a perfect way to connect with other volunteers and bond over your shared commitment to helping others. Make sure to look for a volunteer opportunity that suits your schedule, isn't too far from where you live, and is something that you will ultimately find fulfilling. Also, consider an opportunity that allows you to spend the majority of your time outside given your love of outdoor activities. 
3. Book Club. If you are someone who enjoys reading and discussing what you're reading with others, consider joining a book club. Book clubs are often organized monthly and involve meeting as a group to discuss a particular book that's been designated for that month. Not only will you get to read and talk about an interesting selection of new books, but joining a book club is a perfect way to expand your social circle and get to know a large group of people who share your interest. 
4. Running Groups. As someone who enjoys outdoor activities, you may want to consider joining an organized running group. A common practice in such groups is to go on fun runs that take place in different places around the city. It may not seem like you can easily get to know people by running with them, but rest assured that there is usually socialization at a restaurant, cafe, or brewery before or after the run, which makes it a great opportunity to get to know new people.
5. Trivia Nights. It's extremely common for bars to host trivia nights on specific nights of the week in order to provide a fun group activity for their customers. Make sure to look for one that's geared toward matching up strangers instead of expecting people to come in their own groups.   

I hope that you are able to utilize these suggestions to make some new friends in your city. Good luck!
