I've been coming here for years and I absolutely love the trails. It is well maintained and has variety for all rider levels. The reason why I gave it 2 stars is because of an incident that occurred with a staff member at the trailhead. I am aware that at the beginning of every year they make sure everyone has their annual pass, which is absolutely fine by me. At the time it slipped my mind to renew my annual pass. As I was driving into the trail head he jumps in front of me which caused me to swurve into the gates and luckily no one got hurt. He aggressively demand that I show him the annual pass. I was already upset at the fact that I could've gotten hurt at the manner he jumped in front of my moving bike. So I simply told him.."next time dont jump in front of a bike, we can both end up hurt"..he said "whatever". Anyways I went to the office to update my annual pass. Again, I was asked with attitude by some lady which didn't even present herself if I was the person at the trailhead arguing with a staff member. She says "hes looking out for your safety". After I informed her in the aggressive manner in which he did it, she said "he's just doing his job". I insisted that he be trained professionally when it comes to handling the entrance trailhead. She was dismissive the whole time. So my advice to markham is to have someone mature and trained at the trailhead before someone gets hurt. If the fact is that this young kid was trained then clearly he wasnt applying it..being on his phone and all. Please take this advice markham, dont just send a reply stating excuses. Aside from the incident markham park is great.
