Can I bring my camera/camcorder?

  • Yes!
  • Getting a camera into the trees is straightforward; you just need a lanyard to make sure your camera is always attached to you.
  • We ask that you be courteous of other treetop dwellers by not taking too much time on platforms to take photos or video (only 3 people are allowed on a platform at one time).

Can I carry a backpack, fanny-pack or pocketbook?

  • No. Any bag would interfere with the fitting of the safety harness and your ability to navigate through the games. Water bottles can be carried if attached with a carabiner.

  • Once you are in the trees you will have Adventure Guides and Monitors on the ground. These folks are available to coach and cheer you on as needed (or desired) throughout your adventure.
  • The guides are available to bring you down (via belayed rescue) if you reach a point where you cannot continue and cannot reach an exit platform.

I'm afraid of heights!

  • You may find that with the friendly and supportive training, coaching, and assistance from the ATA staff, you will feel confident to do things you never dreamed possible. The ATA Guides and Monitor staff take pride in their ability to “boost” your confidence and get you through even the most challenging obstacles. Many people with a fear of heights use our ATA to conquer their fear as they conquer each course, and come back repeatedly to get even more comfortable with heights. Why not give it a try - you might surprise yourself!

Is it safe?

  • Safety is paramount at Gunstock’s ATA Course.
  • Guide staff will talk you through, walk you through, and then observe you in the demonstration course to make sure you are capable of performing the moves you need to make it ATA w Staff Sqthrough the course safely. Staff will guide you through the safety protocol, teach you how to use the safety equipment, and make you feel comfortable in the fact that you will be safe throughout the adventure.
  • That said, Gunstock’s ATA courses are substantial and physically testing treetop adventure courses, which feature various ziplines and obstacles. There is inevitably a risk of injury when undertaking such activities. Participants will be responsible for attaching themselves to the safety system. If you do not attach yourself to the safety system you risk falling, which could result in a serious or fatal injury. However, the treetop course has been built to and operates under strict safety standards.
  • The course is inspected daily, monthly, and annually for adherence to these safety standards.
  • All participants receive a safety briefing from a trained instructor at the start and have to wear a safety harness at all times.

Do I need to be fit or strong?

  • ATA does require a degree of physical fitness, but if you can climb up a rope ladder, you should be fine. You can always catch your breath between obstacles.

Can we watch our friends and family from the ground?

  • Yes, spectators are more than welcome to watch friends and family zipline, swing and crawl, from tree to tree from the trails below along most of the courses. Signs and guides will point spectators away from restricted areas.

What happens if I get stuck?

  • Adventure Guides will come to your rescue! They have special equipment to get you to the nearest platform or safely off of the course.

What if I fall?

  • If you should fall your safety harness will catch you. Then you can regain your footing and continue through the course.

What happens in bad weather?

  • ATA is an excellent wet weather activity but is even better when dry! The course remains open in all weather conditions, except when it is icy, stormy or during lightning. Rain makes the course slicker and the ground muddier than usual - which all adds to the fun and adventure for many people! However, since you are beneath the forest canopy, it is a lot drier than standing out in an open field. Whatever the case is, dress for the weather. You may want to bring a change of clothing for the journey home.
  • Sometimes, unfortunately, we might need to close the Adventure Park for reasons beyond our control and if you have already started the tour we will do our best to find alternative dates or times for you and your party to visit again. You will be issued a “Rain Check” to use prior to the end of the current season. Rain checks are transferable but are only valid for the adventure for which it is issued, therefore, all participants must meet the age, height, and weight requirements of that adventure.

Can I do the course if I'm pregnant or have a pre-existing medical condition?

  • The Adventure Park staff at Gunstock Mountain Resort are not medically qualified and not in a position to assess the capacity of participants with pre-existing medical conditions to undertake a treetop adventure course. It remains your responsibility to undertake such an assessment prior to taking the tour. We advise you to visit the resort prior to attempting the course. You may also wish to contact your doctor for further advice.
  • We recommend that pregnant women do not take part in the treetop adventure course (as it is a robust zipline and ropes course and there are associated risks). We do not operate with full body harnesses, but have sit harnesses. Unfortunately, we cannot allow customers to wear their own harness due to our own insurance position.
  • We are not medical experts and therefore suggest that you seek advice from your doctor on the matter. If you decide to proceed, you do so with the full knowledge that the treetop adventures may incur risks to an unborn child.

Can I bring my dog?

  • Dogs are welcome at Gunstock Mountain Resort but must be supervised and remain on a leash at all times. You must clean up after your dog while on resort property.
  • Please do not leave any animal in your vehicle unattended. We care about all animals and will take necessary measures if a dog is spotted unattended in a vehicle, including contacting authorities.
  • Your dog cannot accompany you to or under the ATA.
  • During Winter Snow Sports season, dogs are not allowed on any snow surface.
