Go paintballing
It takes the right kind of girl to go paintballing with you, and it helps to have the gear, but this can be a highly adventurous and fun activity. And you definitely need a group.
Sneak in to a ritzy hotel to go swimming in their pool
Most places don’t care as long as you’re quiet. It’s pretty easy to stroll in and park as if you are checking in and then sneaking back to the pool area. Have your swimsuit on under your clothes, then just strip down and hop in! Many “ritzy” resort style hotels have some really sweet pools.
Go cliff jumping
Ask around and you can probably find a nearby lake or river that’s well known for cliff jumping. Usually better in a group and definitely a daytime activity. Combine this with a picnic or barbeque and you have yourself a party!
Go boating
Most people don’t think of this as a date, but it’s great for a group. If you know someone with a boat, you can go water skiing, tubing, wakeboarding, knee boarding, etc. etc. at a nearby lake.
Raft or tube down a river
There are rivers of varying speed and rapid-ness just about everywhere. Grab a tube or raft, some drinks and maybe some music and hit the river! Make SURE to bring sun screen.
Visit a nearby, quaint little town (like Sedona, AZ)
Every state seems to have a small town that is well known for tourism. In Arizona, it’s Sedona where you can see red rocks and check out all kinds of neat little shops and trails. There are others in other places – go look for them!
Take a horseback ride
If you don’t know someone with horses, this can be difficult. You can choose how long you go for and where to. You can also decide whether to ride together or to split up. Great opportunity!
Go on a picnic or picnic in the woods
Picnics are great for short, eating food, and of course talking. Combine this with another idea like playing cards or a board game! Alternatively, you can do it in a slightly more public place like a park and have fun people watching.
Watch an air show
Again they don’t happen all of the time, but when they come you don’t want to miss them. Air force bases put on the best shows, and often times there are planes parked on the ground that you can walk around and look in. A good chance to get up close!
Go to a racetrack (horse race, drag race, etc.)
There are all kinds of races — pick one that you will both like. I went to a 1/4 mile racetrack nearby once. It was a little pricy, but one of the coolest things I’ve ever seen (as someone who didn’t grow up around those kinds of things).
