Review: Pound for pound, probably the greatest official Long Island Mountain Bike course that there is. The main loop is about 4 miles but sections of it are tight and there's some elevation changes that may be too much for a beginner.

There's just over 9 miles of diamonds, both single and double. There is constant up and down flow which is great for plenty of fun when riding or trying to increase your time for a good workout. There's some small logs to roll over, some rocks from small to large rollers to ride over, and plenty of tight twisty flow turns. There's some moguls as well. This is a great trail to learn the technique of standing when riding and turning. If not you're going to be sorry as you will get banged up from some trees. Watch for some stops along the side of the trails that can give you a good endo toss.

The trail is setup like none other. Everything loops around and you can do a diamond two or three times if you want without having to do another diamond. You can ride this trail with a few inches of snow on the ground as well.

Total miles is close to 13.5.When you're on Long Island and are in shape this trail flows like no other. Come get some, you won't be disappointed!

It is maintained by an unbelievable individual named Hitch. If you see him working in there thank him for his efforts. The guy is amazing!

Review: Trail is outstanding, fast, flowy, and maintained terrificly. Definitely the best trail on LI.

Review: This trail is amazing. This trail includes intermediate, diamond to three double diamond extensions. The trial is well maintained and marked. The 992 global ranking is not accurate. Patapsco Valley State Park Maryland is ranked 23rd, but Glacial flows better. Glacial Ridge should be ranked at least 22nd or 24th. For free maps go to http://www.climbonline.org

Review: Head up. Elbows in. This trail is super tight. Incredibly fun to ride though with some fast downhills and some nice moguls. Does not feel like Long Island at all. Easy to get to. Seems to be marked better than some say in their reviews. Work on slow speed handling before heading out.

Review: Rode this trail only once and it can definitely be labeled better in some areas, I kind of lost my way after going threw the first Black Diamond, then eventually found my way back only to be surprised on how short the main loop was. I will definitely try again and explore some more as a few folks here claim it is 11 miles plus and I only realized about 4 miles.

Review: This trail is now about 11 miles. Lots of tight technical riding. Little climbing but what it lacks in climbing Glacier Ridge makes up for in technical riding. Some nice uphill switch backs.

Review: Is this really Long Island? Glacier Ridge has nice switch back climbs, fast descents, steep moguls, and of course "The Ridges." The trail is set up awesome and it gives a moutain feel to a place where there are no Mountains.

Review: Really zen like, flowing trails. Nothing too technical, just really well designed single track. I went with a few guys that knew the trails which is good because it's easy to get lost- everything looks the same. My buddy said that if you do all the loops, it's about a 26 mile ride.

Review: This is a new trail and somewhat soft. Killer tight and narrow. Some super diamonds with great moguls. This will totally test your slow speed handling skills. Gotta do this one again.
