I can't make a reservation online. Why?

We operate from mid-May – mid-Sept. If you try to book before we are open for the season or if we have already closed, you may not be able to book reservations. May-Sept if you are not able to book and secure a date/time, it is because there is no reservation availability or it is less than 24 hours in advance. 

Where can I find you at the lake?

Click HERE for directions and how to find us. Once you are at the lake, look for our pop-up tents and feather-flag signage! Our staff is stationed near our storage containers under the tents.

> Horsetooth Santanka Cove: we are located near the boat dock across the bridge. Park permits can be purchased near the parking lot.

> Horsetooth South Bay: we are located by the swim beach. Park permits can be purchased at the manned station at the entrance of South Bay.

Do I need to also buy a park permit?

Yes! Park Entrance fees are not included with the rental. Daily entrance permits are available at entrance stations and self-serve stations prior to entering the parks. A park permit is required to visit Horsetooth Reservoir or Carter Lake. It is $10 per day/per car for a day pass. You must purchase it directly from Larimer County Parks. Park permit info:

Where should I park?

Weekends are very busy, and the parks are usually at peak capacity between 11am & 3pm. Be patient in finding parking as there is limited parking available at the Horsetooth locations. At Carter Lake, you should be able to find parking near our rental location at South Shore.

We have a variety of inflatable and hard boards. We will size you up to equipment that will accommodate your height/weight. Generally, the boards have a weight capacity of 385 lbs.

Yes! They must wear a coastguard-approved PFD at all times. Weight totals for everyone on board should not exceed the total weight limit for the paddleboard.

Can I bring my infant on the board with me?

No, we would not recommend that you bring a child too small for a coastguard-approved PFD. 

What if I need help while I'm on the water?

We provide a whistle that is attached to your board along with your life jacket. Should you need help, blow the whistle! 

What happens if it starts raining or becomes very windy while I'm out on the water?

You need to get to land immediately. It is unsafe to be out on the water, even a short distance from shore, during inclement weather. If you return the equipment early due to inclement weather you will be charged the hourly rate for the time you were out.

Our mountain lakes are very cold until about mid-summer. In May, water temps are on average around 30-40℉, June 40-50℉, July 50-55℉, August and Sept 55-60℉.

You can find current water temps here:

If you return the equipment because you no longer wish to use it, you will be charged the full amount.

How early should I show up for my rental?

Arrive 15-20 minutes before your start time (during peak season) for instructions and safety equipment fitting. We make every effort to get you started on time.
