What are the driving directions to Mile Hi Rafting?

Take I-70 west out of Denver. Take exit #234 for Downieville Lawson. At the stop sign at the end of the exit ramp, take a right and then an immediate left as if you were going to the Taco Bell. You will be on County Road 308. Proceed on County Road 308 for one mile, (you will go under I-70 one time.) At the one mile, turn left on to Alvarado Road (County Road 306)the only road crossing over Clear Creek. Mile Hi Rafting and ATV tours will be on your right as you come out of the trees in only 0.2 miles.

Should I wear sunscreen?

Yes. Water and high altitude amplify the Sun’s rays. To be most effective, it should be applied in advance (like before you leave from Denver). Your face/neck area is the most important, since you will be covered with a wetsuit, splash jacket, helmet and shoes (or booties). If a warm day you may not want to wear the splash jacket—so your arms will also need sunscreen. Please wash your hands with soap and water after applying the sunscreen since slippery hands will make it difficult to grip the paddles.

Do you provide transportation from Denver?

No but there are several Uber and Lift drivers in the area.

If I am pregnant can I still participate?

Please check with your doctor.

If I have a bad back can I participate?

Please check with your doctor.

Where should I leave my valuables, like a purse or wallet?

Can I bring my own water bottle?

Can I bring a camera?

Yes, but only if it is a waterproof camera and it has a strap or lanyard so that it can be tied to your life jacket or vest. You will not be able to get action shots of the rapids—since you will be the action. There is a professional photographer, who will be taking pictures of your rafting trip at the rapids, and have them for sale at the end of your adventure.

Can dogs go on the raft?


What are maximum/minimum weights for rafting?

The minimum and maximum are determined by the PFD (personal floatation device). The minimum is 50 pounds. The maximum is the chest and waist are not more than 52 inches.

Does the raft stop along the way?

Yes. The rafts will stop along the river to regroup for safety, so all our rafts remain together. There are no restrooms along the river.

How long are we on the river?

Depending upon the trip you choose between 60 to 90 minutes. Water flow will impact time. The beginner trip ‘Sure Shot’ you are on the river for 6 miles; intermediate trip ‘Blast’ 8 miles; Kamikaze trip 10 miles; the advanced Full Day Ultimo is 21 miles taking approximately 6 hours with lunch.

How many fit on a boat?

Normally 6 plus your guide. Water Level can affect this and weights of participants. Group sizes also impact the number as we do not split people that are in a group together unless in a group of more than 6. Then the group will be in different boats but in the same ‘pod’ going down river. Minimum on a Boat is 4.

When does rafting on the Arkansas River start/end?

Some parts of the Arkansas can be rafted most of the year as the Arkansas River is used to move water for agriculture, towns and municipalities. Rafting has a guarantee of water June 15 through August 15. August 15 the river is returned to native flow for the fishery and fishing.

When does rafting on Clear Creek start/end?

Traditionally we can start rafting on Clear Creek mid-May. This depends on the spring runoff. Clear Creek is all snow melt. When days and nights warm, the river will start running. When all of the snow is melted, rain can augment the water. We traditionally can get through the 3rd week of August with a good snow pack year. We have been able to raft once in 17 years on Labor day on Clear Creek.

Where is the Arkansas River?

125-160 miles south of Denver on I-25 or HWY 285, depending on which section of the river you are going to.

Where is Clear Creek?

30 miles west of Denver along I-70

What is the difference between the Arkansas and Clear Creek?

The Arkansas River is the most rafted river is the Americas. Clear Creek runs 3rd or 4th. The Arkansas is the only river with guaranteed recreational use. Arkansas River is a pool drop—meaning you are paddling to get to the rapid, go through the rapid and then paddle to the next rapid. Clear Creek is continuous, being the steepest commercially rafted river in Colorado—therefore you are paddling to stay on top of the rapids.

What difficulties & types of rafting trips does Mile Hi Rafting offer?

Mile Hi Rafting offers beginner, intermediate and advanced rafting trips. There are half-day rafting trips and all-day rafting trips. Full day rafting trips have lunch provided on the river bank. All trips have the option of fresh hot food from our Chuck Wagon food truck. For more details about the rafting trips, go to click here.

Do I have to rent booties?

No, you can wear any shoes that have a full heel and toe and fasten securely to your feet. Tennis shoes are fine, but keep in mind that they are going to get soaking wet, (flip-flops and clogs are NOT acceptable).

Can I wear my prescription glasses or sunglasses?

Yes, but make sure that they have some sort of strap or restraining device. We sell Chums to secure your glasses, especially if they are expensive. You will definitely get splashed and the water will take them off — there is a possibility that you will fall overboard also.

Where shall I leave my keys if I don’t want them to get wet (electronic remote, etc.)?

All keys should be left with the office staff—a set has never been found on the river.

Who has to sign the Participant Release of Liability & Assumption of Risk Agreement?

Everyone participating in the raft trip must sign this form. For participants under age 18 at the time of registration, the Parent/Guardian of participant must also sign and date the form.

Can I bring my cell phone.

Bad idea. Water and electronics do not mix. Leave your cell phone in your car.
