Quandary Peak

What to Expect

Below treeline (10,850 to 11,300 feet): The forest trail is shaded, with a moderate grade and good footing. Expect to be warm if you start after sunrise on a summer day.

Treeline to ridge (11,300 to 12,000 feet): In this transition zone, the trees thin, the wind picks up, and the temperature drops. Put on your wind layer here if you have not already.

Ridge to summit (12,000 to 14,272 feet): This stretch is fully exposed, with no trees and no shelter, and the wind can be significant. The summit is typically 20 to 30 degrees colder than Breckenridge. You are also above the altitude where most people start feeling the effects of thin air.

Crowds: Quandary is busy. On summer weekends, expect a steady stream of hikers on the trail from sunrise to mid-morning, so do not come looking for solitude. The upside is that the trail is so well traveled you will never wonder if you are on the right path.

Wildlife: Mountain goats are common above treeline on Quandary. They are used to people and will sometimes approach hikers. Do not feed them or get close, because they are wild animals with sharp horns.

Gear Essentials

You do not need a lot of specialized gear for Quandary in summer, but you do need the right basics.

Footwear: Wear hiking boots or trail runners with good tread, because the trail is rocky above treeline. Sandals and running shoes are not appropriate.

Layers: Bring a base layer, an insulating layer, and a wind and rain shell. Even on a sunny July morning, the summit can be cold and windy, so pack your layers even if the parking lot feels warm.

Water: Bring at least 2 liters, since there is no water source on the route. On hot days, 3 liters is better.

Food: Pack high-calorie snacks you can eat on the move, like trail mix, bars, and sandwiches. You burn a lot of calories over 4 to 7 hours.

Sun protection: Bring sunscreen, sunglasses, and a hat. UV exposure is intense above 12,000 feet, and you will burn faster than you expect.

Trekking poles: Poles are not required, but they are recommended, especially for the descent. They save your knees on the rocky sections and help with balance when you are tired.

Rain gear: A lightweight rain jacket is non-negotiable. Summer storms in the Colorado mountains are violent and sudden, and you do not want to be above treeline in a thunderstorm without a waterproof layer.

Headlamp: If you are starting before sunrise, you need a headlamp. Bring one even if you plan to start after dawn. If something goes wrong and you are out longer than expected, you do not want to descend in the dark without light.

Common Mistakes

Starting too late is the number one mistake. On Quandary, starting too late means leaving after 7 a.m. in summer. Afternoon thunderstorms build fast in the Colorado mountains, often by noon or early afternoon, and if you are still above treeline at 1 p.m., you are playing a dangerous game. Start early, summit by noon, and be below treeline by early afternoon.

Some hikers show up with no parking reservation. Every summer, people drive about 1.5 to 2 hours from Denver, arrive at the trailhead, and discover they cannot park because they did not know about the reservation requirement. The rule applies from mid-June through mid-September, so check hikequandary.com before you go.

Underestimating altitude catches a lot of people. The trailhead is at 10,850 feet, and if you live at sea level or low elevation, you will feel it. Symptoms include shortness of breath, headache, nausea, and fatigue. Spending a night in Breckenridge (9,600 feet) before your climb helps with acclimatization. Drink water and go slow, and if symptoms get worse as you climb, descend.

Not bringing enough water makes everything worse. Dehydration compounds altitude sickness. Two liters is the minimum, so bring more if you run hot or the forecast is warm.

Cotton clothing works against you. Cotton absorbs sweat and does not dry, and above treeline, wet cotton in the wind will chill you fast. Wear synthetic or merino wool layers.

Ignoring the weather is a serious mistake. Check the forecast the night before and again that morning. If thunderstorms are forecast for early afternoon, adjust your start time. If storms are forecast all day, pick a different day, because no summit is worth a lightning strike.

Some hikers push on when they should turn around. There is no shame in turning back. If you feel sick, if the weather turns, or if you are not going to make the summit by noon, going back down is the right call. The mountain will be there next weekend.
