There’s a lot to discover in Denver, but if you’ve lived here for years, it can be easy to fall into continuously returning to your same old haunts. Enter Let’s Roam, an app that turns a day out into a scavenger hunt adventure. To start, buy an $11 ticket for your preferred hunt (there are even themed options for dates, birthdays, and bachelorette parties), then let the app guide you from landmark to landmark. Not only will you see some iconic Denver sites, you’ll also learn some things along the route and give your outing a fun competitive edge as you answer trivia questions, solve riddles, and complete photo challenges. Bonus: Though the company is Denver-based, they offer scavenger hunts in more than 400 cities around the world, so you can take a bit of the Mile High adventuring spirit with you on your next vacation.
