About this Location

Facility Overview

The Wooly Mammoth Lot, officially designated as the Wooly Mammoth Park-n-Ride, is Colorado's most iconic and heavily utilized mountain rendezvous facility. Located at 18540 U.S. Highway 40 in Golden, Colorado, the lot sits directly off Interstate 70 at Exit 259 in the Hogback area between Golden and Morrison. Spanning a sprawling open-air footprint with 918 dedicated paved parking stalls, it is the largest of CDOT's trio of celebrated 'Dinosaur Lots' (alongside the adjacent T-Rex and Stegosaurus lots). Because the facility is entirely an expansive, single-level open surface lot, there are zero overhead clearance restrictions. This open layout effortlessly accommodates high-profile adventure vehicles, including lifted 4x4 trucks, full-size SUVs with roof boxes and ski racks, overland rigs, and high-roof passenger campervans.

Prime Location & Nearby Attractions

Serving as the quintessential transition point between the Denver metropolitan area and the Rocky Mountains, the Wooly Mammoth Lot is positioned moments from top regional recreational and entertainment hubs:

Red Rocks Amphitheatre & Park: Situated just 2.5 miles south (a 5- to 7-minute drive or rideshare trip), making this lot a top designated meeting and carpool station for world-class concerts, yoga sessions, and Film on the Rocks.
Matthews / Winters Park & Dakota Ridge Trail: Located directly across the highway corridor, providing instant pedestrian and bike trail access to scenic foothill hiking and mountain biking along the Hogback.
Dinosaur Ridge: Positioned roughly 1.5 miles south along Rooney Road, this national natural landmark showcases authentic dinosaur tracks and interpretive fossil displays.
Historic Downtown Golden & Colorado School of Mines: Approximately 5 miles north via US-40 and Heritage Road, offering boutique shopping, craft microbreweries, and dining along Clear Creek.
World-Class I-70 Ski Resorts: Less than an hour's drive to Loveland Ski Area and Arapahoe Basin, and convenient to Keystone, Breckenridge, Copper Mountain, and Vail.

Access, Navigation & Transit Connectivity

The lot delivers unmatched vehicular connectivity thanks to its strategic junction at I-70 Exit 259, U.S. Route 40, and nearby Colorado State Highway 470 (C-470). Broad two-way entry and exit aprons directly off US-40 ensure fluid ingress and egress, easily processing heavy weekend traffic waves. Beyond personal carpools, the Wooly Mammoth Lot serves as a crucial CDOT transit node. During the winter ski season, CDOT’s Snowstang express bus boards passengers at the lot's upper shelter, shuttling skiers and riders directly to destinations like Breckenridge, Copper Mountain, Loveland, and Arapahoe Basin. In addition, the RTD W-Line light rail terminal at Jefferson County Government Center Station is located roughly 3 miles to the northeast for rail connections into Downtown Denver.

Visitor & Driver Tips

Because parking at the Wooly Mammoth Lot is entirely free and non-reservable, spaces fill rapidly on peak powder days, winter ski weekends (typically between 5:30 AM and 7:00 AM), and during sold-out summer evening concerts at Red Rocks. Arrive early to secure your spot, and agree on a specific aisle or marker with your group beforehand, as the expansive 900+ stall layout can make finding companions challenging. While CDOT permits overnight parking for mountain weekenders, vehicles left for multiple consecutive days without moving risk tagging or towing as abandoned property. Always secure your vehicle, lock all doors, and keep valuable electronics, outdoor gear, and ski equipment strictly out of plain sight.
