Highlights

Highlight: Winiger Ridge (Gross Reservoir)
Located 45 minutes southwest of Boulder, Winiger Ridge is the only 4wd road that allows access to the western side of Gross Reservoir. This easy trail is great for weekend camp trips with friends or day trips to the lake for some fishing, kayaking, or paddleboarding. Kick back, relax, and enjoy the scenery. Be aware that there is no swimming allowed in Gross Reservoir. This trail is a little rough but short and easy enough that any 4WD enthusiast can do it. Just be aware the trail could be crowded with other drivers and many hikers and is only a single car wide.

Mapping Crew - Colorado

Hi, I'm Ryan! I am a Colorado native and I've been wheeling since I was 16 years old. I grew up with a relentless passion for all things Jeep and off road related, and that passion has never died out. I am a member of the Mile-Hi Jeep Club, Patrol 16 Sasquatch Jeepers and currently own an '06 Jeep Wrangler Rubicon Unlimited (LJ) nicknamed "Minion". I am a huge supporter of Stay the Trail and Tread Lightly, and have participated and even been in charge of many trail restoration projects. I have been a trail leader several times for events such as All-4-Fun, ColoradoFest, Set Them Free, 14er Fest, and other. I am also the creator of the Unlimited LJ Adventure. My rig is built for extreme offroading, but I love to get my tires dirty on any kind of trail whether it's rock crawling or just scenic high Alpine drives. I've wheeled all over the country including Colorado, Utah, Kansas, the Carolinas, AZ, and California. I love a great adventure, and love even more to share those adventures with others. If you see the "minion" out on the trail, make sure to stop and say hello.
