Standing at 13,427 feet on the Continental Divide, Grizzly Peak is one of the most accessible and rewarding thirteener hikes near Denver — and one that demands proper planning before you ever set foot on the trail. The mountain earns its name. Grizzly Peak is a challenging 5-mile hike from Loveland Pass that ends with a scramble to its craggy 13,427-foot summit, delivering breathtaking views of the Loveland Pass area, local ski resorts, and the 14ers Grays and Torreys Peaks. Getting there from Denver, timing your arrival, understanding the road conditions, and pairing it correctly with an evening at Red Rocks Voyager country on the way home — this guide covers all of it.
Grizzly Peak at a Glance

Because the trailhead is at Loveland Pass on a paved road, it is accessible to all passenger vehicles — making Grizzly Peak one of the most convenient high-altitude thirteener hikes in the state. That convenience, however, does not make the transportation planning any less important. Read the Red Rocks scenic transportation guide for context on how Colorado mountain road driving works and why early departures from Denver matter on peak-bagging days.
Getting to Grizzly Peak From Denver — The Full Transportation Breakdown
Grizzly Peak transportation from Denver is straightforward on paper but rewards careful timing. The trailhead sits at the summit of Loveland Pass on US Highway 6, approximately 60 miles west of Denver. Here is how to get there by every available method:
Driving From Denver
From Denver, take I-70 West. Just before the last ascent to the Eisenhower Tunnel, keep an eye out for the Loveland Pass exit. It is the former US Highway 6. The exit is located on the north side of the interstate, crosses beneath it, travels west to the Loveland Ski area entrance, and then turns sharply to the left to start the ascent to the pass. Under normal circumstances, the drive from Denver to Loveland Pass takes about 60 to 75 minutes. The interstate can back up considerably between Denver and the Eisenhower Tunnel on busy weekends from late spring through autumn, so factor in extra time on weekends, holidays, and any morning when I-70 ski traffic is operating.
The trailhead at Loveland Pass has capacity for about 25 vehicles with additional roadside parking on the opposite side of the road. Because of this, the lot fills fast. Plan to arrive early and carpool when hiking with friends. Be aware of vehicles coming over the pass when crossing the road — they can come at high speeds and visibility is limited. There are no restrooms or facilities at the trailhead. Plan accordingly before leaving Denver. Always check Colorado Department of Transportation road conditions before departure — Loveland Pass road conditions change rapidly in spring and autumn, and US Highway 6 can close temporarily during severe weather events.
Carpooling — The Smartest Grizzly Peak Transportation Option
With only 25 to 30 parking spaces at the trailhead, carpooling is not just a convenience — it is the responsible approach to Grizzly Peak transportation from Denver. Filling a vehicle with your full hiking group reduces trailhead congestion, cuts fuel costs, and removes the risk of arriving to find the lot full. Arrange your carpool the night before and commit to a 5:30 to 6:00 AM departure from Denver to guarantee a parking spot, especially on summer and autumn weekends.
I-70 Mountain Shuttle Options
For those who prefer not to drive mountain roads, several Denver-based outdoor shuttle companies run services toward Summit County and the Loveland Pass area during peak hiking season. These services typically depart from central Denver or specific park-and-ride locations along the I-70 corridor. Check the US Department of Transportation resources and Denver city transit guides for current public transportation options operating toward Summit County. The RTD mountain service options change seasonally so confirm schedules before your planned hike date.
What to Know About Loveland Pass Road Conditions Year-Round
Loveland Pass sits at 11,990 feet — higher than many Colorado ski resorts at their peak elevation. That means road conditions at and near the trailhead can vary dramatically by season and even by day:
Spring (April–May). Grizzly Peak trail accumulates cornices on its eastern edges, which means avalanche danger and the danger of falling through the cornice if walking upon its surface. Though most years, most of the trail is discernible in winter months, heavy snows can change the landscape and cover the trail without warning. Spring snowmelt makes the US Highway 6 approach occasionally icy in the early morning. Carry traction devices in your vehicle and check road conditions through CDOT the morning of your hike.
Summer (June–August). Road conditions are reliable and the drive is straightforward. Thunderstorms can appear quickly, so climb early before the early afternoon thunderstorms roll in during the summer months. I-70 weekend traffic is the main variable — leave Denver no later than 6:00 AM on summer weekends to avoid the ski and tourist traffic that builds from 7:30 AM onward. Always check the National Weather Service forecast before departing.
Autumn (September–October). The most reliable window for Grizzly Peak transportation from Denver in terms of road and weather predictability. Early snowfall can arrive from mid-September onward — carry an ice scraper, check road conditions, and watch for early-morning frost on US Highway 6 above 10,000 feet.
Winter (November–March). Loveland Pass remains open year-round but winter driving on US Highway 6 requires all-wheel or four-wheel drive and proper winter tires or chains. The Federal Highway Administration mountain road guidance applies fully here — do not attempt Loveland Pass in winter conditions without an appropriately equipped vehicle and winter driving experience.
The Trail — What Happens After You Park
Once your Grizzly Peak transportation is sorted and you are standing at the trailhead on top of Loveland Pass, here is what to expect on the mountain:
The opening climb (0 to 1.0 miles). The hike begins by climbing a short set of rock steps up to the trail. The first mile or so is deceptively steep without switchbacks, but will take you to the ridgeline very quickly. Take your time ascending this section and warming up to the high altitude. The altitude is real and immediate — you start at 11,990 feet and gain elevation fast. Slow down, breathe deliberately, and let your body acclimatize before pushing pace.
The Continental Divide ridgeline (1.0 to 2.5 miles). Once at the top of the first hill, head right towards Grizzly Peak. This section provides multiple miles of enjoyable rolling ridge traversing with incredible views along the Continental Divide. The hike to the base of Grizzly includes several miles and about a thousand feet or so of up and down at elevation. This middle stretch is where most hikers find their rhythm — the terrain is open tundra, the views are expansive, and the summit still feels distant enough to enjoy the journey.
Cupid Peak (around 2.5 miles). From Pt. 12,915, a trail continues along the ridge to the SSE for 0.9 miles to Cupid Peak. Drop about 200 feet in elevation to the saddle, then regain 400 feet to the Cupid summit. The terrain is mostly broad tundra slopes with large rocks scattered around. Cupid at 13,117 feet is a genuine thirteener in its own right and a natural rest point before the final push.
The final ascent to Grizzly (2.5 to 2.9 miles). In just 0.2 miles, you will ascend around 600 feet of elevation. It is a rocky scramble up to the top — be prepared. The remaining 0.4 miles up Grizzly Peak are pretty steep and on loose rock. Be careful of your footing and take your time. This final section deserves your full attention — loose scree, exposure, and altitude combined demand careful foot placement on every step.
The summit. Views from the summit include A-Basin Ski Area to the west, the Continental Divide to the northwest, Grays Peak and Torreys Peak to the east, and many more mountains to the south. Once at the summit, the trail continues on to Torreys Peak, a 14er, and then on to Grays Peak — another 14er. Take in the views of these peaks as well as a bright blue lake just south of the Grizzly Peak summit below. This is the payoff. Take your time, eat something, and absorb one of the most extraordinary panoramas in the Colorado Front Range before heading back down.
Adding Mount Sniktau — The Triple-Header Option
Combining Grizzly Peak with Cupid Peak and Mount Sniktau in one day is one of the most fulfilling peak-bagging experiences close to Denver for hikers who are highly fit and have early start times. Your trip will be roughly 7.5 miles long and take 4 to 6 hours if you include Mount Sniktau in your itinerary, which adds about 2.4 miles. Mount Sniktau, Cupid, and Grizzly work well together for a quick triple header day that can get you back to your Front Range house well before supper. For the triple, start no later than 6:00 AM from the trailhead, aim to finish by noon at the latest, and monitor the weather all morning.
Essential Grizzly Peak Transportation and Hiking Tips
Leave Denver by 5:30 AM at the latest on weekends. The 25-spot trailhead fills before 8:00 AM on busy summer and autumn weekends. There is no overflow shuttle for Loveland Pass — if the lot is full, you either wait for a spot or add roadside parking distance to your hike. Neither is ideal when you have a thirteener to summit before noon.
Check I-70 conditions the night before and morning of. The Colorado Department of Transportation runs real-time road condition updates for all mountain corridors including I-70 and US Highway 6. Never drive to Loveland Pass without checking conditions first in spring, autumn, and winter months.
Bring more water than you think you need. At altitude above 12,000 feet, dehydration accelerates dramatically — especially on a sustained climb. Carry at least two to three liters per person and consider a water filter if planning a longer route extension toward Torreys or Grays.
Never ignore weather on Grizzly Peak. Afternoon thunderstorms are common in this area and can roll in without warning. It is a good idea to get an early start and plan to be back at the trailhead before early afternoon. The entire Grizzly Peak trail is above treeline — there is no shelter anywhere on the route if a storm moves in. Summit and descend before noon, without exception.
Pack the 10 Essentials without exception. Navigation, sun protection, insulation, illumination, first aid, fire starting, repair tools, nutrition, hydration, and emergency shelter. At 13,427 feet on a remote Continental Divide ridge, self-reliance is not optional. The National Park Service and BLM Colorado both publish detailed guidance on safe mountain hiking practice for hikers planning routes in areas like the Arapaho and Roosevelt National Forests.
Wildlife awareness matters here. This area is mountain goat country — upon closer inspection you will find scattered throughout the trail winter wool which the goats shed for the summer. Mountain goats, pikas, and marmots are all commonly spotted along the Grizzly Peak ridgeline. Give wildlife space and enjoy the encounters from a respectful distance.
After the Summit — Combining Grizzly Peak With a Red Rocks Evening
Here is a Colorado day trip combination that experienced outdoor enthusiasts in Denver return to every season: summit Grizzly Peak from Loveland Pass by midday, descend and drive east through the mountains back toward Denver, and end the day at a concert at Red Rocks Amphitheatre in Morrison. The drive from Loveland Pass to Red Rocks runs approximately 75 to 90 minutes — perfectly positioned to get you there ahead of a 6:00 or 7:00 PM show start.
Check the full 2026 Red Rocks concert schedule to plan the evening around your summit day. For the Red Rocks leg of the trip, a professional red rocks car service through Red Rocks Voyager handles everything after your hike — pickup, the denver to red rocks car service run, and a round-trip home after the show. After 8 hours on a thirteener, driving concert traffic and circling for parking is the last thing anyone wants. Read the stress-free ride to Red Rocks complete guide and the Red Rocks parking guide to understand exactly why this matters on busy show nights. See all available services and pricing to plan both legs of your Colorado day.
