alot of fun for mountain biking airways something exciting around every bend, went on 4-20 with my brother and two friends and did the expert trail, shit is extreme definitely not for the cautious or scared rider. real fun tho.
I actually did the Southeastern section, with the entrance being on the southeastern corner of Union Tpke and Francis Lewis Blvd. Did a 2+ mile lunch break hike here. I've driven by a million times, first time I went in. Biggest negative:much of the trail was asphalt. Biggest positive: Decent topography, with a few inclines. Summation: Far better than you would expect in the middle of eastern Queens sprawl. Recommended.
It's really awesome to have mountain biking in the city, and the trails here are very well made and a lot of fun. Some of the diamond sections seemed more dangerous than difficult, and it seemed like certain spots on the blue squares were meant to be on black diamond trails. Otherwise, it was amazing!
