Walk or bike to the local farmer's market and buy some produce and snacks for later. After you visit all the vendors, you can have a picnic together.
Take a hike
If you love the outdoors, why not share it with your date? Make sure you stay on well-marked paths in popular areas and that you trust your date before choosing this as a first date option.
Go go-karting
If they're competitive, they won't pass up the opportunity to see you eat their dust as they race you to the finish line.
Play tennis or pickleball
If you haven't hopped aboard the pickleball train yet, what are you waiting for? It's a fun way to get your blood pumping and the rules are easy enough for anyone to learn quickly.
Play mini golf
If you haven't hit the (kiddie) links since you were in school, there's no time like the present. The cheesier the course, the better.
