I purchased the Tree Top Trekking and Big Zip through the website Trythat.ca for a Christmas gift for a friend. We went together on the August long weekend and it was probably the best thing we have done! It was well organized and there was an excellent safety orientation. The employees were all helpful (Thank you Jesse and Jana) and willing to offer any assistance if needed. The courses were challenging yet not impossible. The only one we didn't get to try was the Black level and that was by choice. The Big Zip was also a lot of fun. I would recommend this to anyone that is looking for a few hours of fun and excitement. I will be coming back with my children as well, so that they can put their skills to the test!
