How Do I Get To Quandary Peak and McGullough Gulch?

Colorado 14ers can have patches of snow year round, but the trails are generally clear to hike by mid-summer.

Parking at Quandary Peak & McCullough Gulch is extremely limited and requires an online parking reservation throughout the summer months (June 1 – Sept. 30).  Visitors can also access these popular hikes through a reservation based shuttle system from downtown Breckenridge. Visitors will be able to make reservations starting late May.

    • $25 Monday – Thursday (excluding holidays)
    • $50 Friday – Sunday (plus holidays)
  • 3.5 Hour Reservation – recommended for McCullough Gulch
    • $5 Monday – Thursday (excluding holidays)
    • $20 Friday – Sunday (plus holidays)

Parking is free and first-come, first-serve after 3pm. Visitors hiking Quandary are STRONGLY encouraged to start their hikes early in the morning to avoid dangerous afternoon thunderstorms. The average time to hike Quandary is 6 hours. The average time to hike McCullough Gulch is 2 hours.


Why Do I Need a Reservation?

The reservation system is part of a pilot program put in place by Summit County Open Space & Trails due to significant increases in visitation at Quandary Peak and McCullough Gulch over the past several years, leading to numerous public safety issues. Illegally parked vehicles block emergency access on roadways and limit residents’ ability to access or feel safe in their own neighborhood. The new parking reservation system and shuttle service alleviates these pressures and makes it easier for hikers to safely and legally access the trailheads.

Leave No Trace

  • You can help us preserve and protect what we love by following Leave No Trace practices during your visit. 

Should I bring my dog?

  • While it is not recommended to bring your furry friends, dogs are allowed on the trail but must be kept on a leash. Please bring poop bags and clean up after your pet. Visitors bringing dogs should reserve a parking space and not take the shuttle. Please keep in mind that as you get above treeline, trails often turn into boulder fields and sharp, jagged rocks can harm paws and can be difficult to maneuver. Remember, dogs have to take twice as many steps as you do, and pets and wildlife don’t always mesh well.

  • We understand how exciting it is to see wildlife and it’s ok to take a few photos from a distance without disturbing them. To help keep Colorado’s wildlife – and you – safe, never approach, chase, follow, surround or feed them, and always observe from a distance. Always keep pets leashed and pack out and dispose of all trash properly. Remember, if the animal doesn’t fit behind your outstretched thumb, or alters its behavior, you are too close!
