I agree with Xpat, riding bike is definitely the best option and what better way to burn off all those yummy Krispy Kreme donuts you will inevitably eat!
I ride my bike to the Balloon Fiesta every year. It gets pretty darn cold in the morning after you've stopped riding, but it's worth it 100% when you're passing the car traffic and people walking slowly on foot.
If you can't bike from your house because it's too far, there are a couple of options where to park your car so you can bike the rest of the way on the North Diversion Bike Trail. Both options are a less than 3 mile easy, flat bike ride and the North Diversion Trail leads right to the FREE bike valet on the south side of the field.
- Park your car somewhere in the Journal Center business area. The entrance to the North Diversion Trail in the Journal Center is near the corner of Masthead St (street sign actually says Bartlett St) and Rutledge Rd right by the Heritage Home Healthcare building.
- Park your car off the Paseo Frontage road on the dirt lot (corner of El Pueblo Rd NE and Las Lomitas Dr NE). North Diversion Bike Trail is literally right beside this dirt area.
I have yet to hear a good experience about the Park 'n Ride shuttles.... seems like everyone always misses the events by waiting for these shuttles. It's a good theory, but just never runs smoothly. If you can't bike, I recommend driving and suffering through traffic so you don't miss the early events.
