What an AVA UTV Rental looks like
What to expect
On Your UTV Rental Adventure

Your Rental and Equipment
First things first: You have the opportunity to choose between a turbocharged 1000cc Polaris RZR or a top-of-the-line offroad beast, the 225-horsepower RZR Turbo side by side. Either way, you’ll be set up for adventure with pre-programmed onboard GPS guiding you around the area’s extensive trail system, premium sound, advanced suspension, and LOTS of power.
You’ll need something to get that engine roaring, so we’ll send you off with a full tank of gas included in your rental. Safety is our top priority, so a full-face motocross-style helmet will be included as well with your side-by-side rental. And you can let ‘er rip with peace of mind because the Polaris Adventures Damage Waiver Program is included with your rental, which minimizes your out of pocket cost in case of damage to your vehicle.

Explore Kremmling’s Terrain
Unleash your off-road spirit in Kremmling, Colorado! Explore the vast Wolford Mountain Recreation Area, marvel at the rugged beauty of Gore Canyon, and test your skills on the rocky ascents of Fossil Ridge. Cruise through serene trails at Muddy Creek Pass and relish stunning views at Red Dirt Reservoir.
Don’t forget to bring your camera! You may see antelope, mule deer, elk, coyotes, big horn sheep, hawks and eagles. Whether you’re seeking adrenaline-packed thrills or tranquil nature immersions, Kremmling’s diverse terrain offers an unparalleled side-by-side adventure. Your Polaris RZR UTV will come equipped with pre-programmed onboard GPS so you’ll always know what’s around you, what trails you’re able to explore, some key photo ops and scenic stops, and how to find your way back to the shop.

What to Bring for Your Adventure
Prepare for your UTV adventure by dressing comfortably for a day kickin’ up dirt. Wear sturdy, weather-appropriate clothing, and closed-toe shoes, and bring sunglasses and/or goggles for the motocross-style helmets we provide. Remember, jewelry is best left at home. Bring a sturdy bag or backpack to keep your essentials safe and dry during your side-by-side adventure. Don’t forget to pack a camera to capture the stunning Kremmling views and bring enough food and water to stay energized and hydrated. Energy bars, trail mix, and sandwiches are great for on-the-go snacks. High-altitude adventures can dehydrate you quicker than you think so please don’t underestimate the importance of water!

Safety & Guidelines: Your Off-Road Essentials
We value safety and environmental responsibility just as much as we value fun and adventure. We strictly adhere to the “Stay on the Trail” Program, only allowing guests to use designated OHV trails. Our UTVs are fitted with GPS-enabled Polaris Ride Command 7S Displays, so you’ll always know where you are and where you can go. Side by side renters must be at least 21 years old, and drivers must be 18 or older with a valid driver’s license. Everyone must sign a waiver before hitting the trails, but no previous off-roading experience is required. We use the Polaris Adventures Damage Waiver Program to limit out-of-pocket damage costs to a $3000 cap. However, severe damage leading to loss of rental days may incur extra charges. Please arrive 30 minutes early to your reservation for a smooth start to your adventure. Let’s explore responsibly together!!
