Hi Catherine, We're glad you are planning to come for an ATV tour with us in October. We have been operating tours for twenty years and have had many guests in your age group come out with us to enjoy our ATV and snowmobile tours. Our tours operate on an old mining road which we maintain regularly. It has recently been graded top to bottom and in general it is a reasonably smooth easy ride. There are "water-bars" and stream crossings and other bumps and uneven surfaces that you would expect to find on any back-country road however if you slow down and drive through these areas carefully there is no reason why you should experience any undue problems. If you are concerned then we recommend upgrading to a side-by-side machine as these absorb the bumps very well and we consider them smoother than an ATV. In addition you are seated in the machine rather than riding on top of it and this is probably a more relaxed position, like driving a car. There is more information about our side-by-side units on our website (sorry we are not permitted to post the link here) Our tours are not high-speed - we always advise all our guests to drive at the speed that they are comfortable and in control. We make multiple stops to look at the views and to get off the machines and relax and talk with the guide and other guests. This is also a good opportunity to have a stretch and walk about a bit. In addition we have a nice warm cabin to relax in and enjoy a hot drink and snack or, on the full-day tour, a full BBQ lunch. Please feel free to give us a call if you would like more information or wish to discuss your question in more detail. We do everything possible to ensure your comfort and enjoyment and look forward to your visit. Thank you to all our past guests who have taken some time to respond to Catherine here also - we appreciate your help and support. Best Regards, Toby Creek Adventures
