      The Vietnam Trail Network is one of the most versatile riding areas in the Blackstone Valley, with something for every style of rider, from modest beginners to advanced technical riders - cross country race snakes to big hitters.

      While Vietnam is legendary for its many challenging natural and man-made technical features - you'll see a lot of "big hit" bikes out on the trails - there are ways around most of the technical features and there are many more mellow as well as fast and flowy cross country trails all over Vietnam.

      To see which trails are the most popular, on the map above, hit the “Trail Style” tab to open the drop down list, then hit “Popularity". The trails colored red are ridden most by Trailforks users, while the trails colored green is at the other end of the spectrum.

      Most of Vietnam is served off a few spine trails. Get to know them and you will find everything. You should know The Main Trail which gives you access to all of the more technical stuff up on Rocky Ridge and the Vietnam Land and, below, to the more fun and flowy stuff around Swamp Bypass and Swamp Side, as well as the Fairbanks Trail which leads to the Kitchen, Three Ledges and Toe Jam. The Main Trail also gives you access to the awesome Three Sisters Trail, one of the best flow trails at Vietnam, and Middle Sister, one of the most fun low-tech trails in the Network.

      In the Central part of the Network, everything hangs off the Holliston Highway and the Milford Byway. Both of these are easily accessed from the Adams Street Lot via Adams Lot Trail or New Trail. To get to College Rock you can go up Beaver Brook Way or Top Down, both of which takes you to Farm Way, from where you link to College Rock Run or First Base.

      As a general rule, the further South you go, the more technical the trails. Most of the big technical features are on the trails that start off NEMBA Way - Mind the Gap, Down And Up, Rubber Stamp, Dirty Little Secret etc. If you don't know how to get there, we have created a special Route that you can download to get you to the NEMBA land and back, from the Adams Street Lot.

      While you are up there, don't miss The Gig and Giggidy - both are fun, fast and flowy downhill trails with some awesome tech features.

      The area around Kitchen is a favorite playground amongst regulars for its many rock features. Also popular are the many big rock features such as Whaleback Rock, Optional Rocks, Condo Rock and Dolphin Rock.

      The most popular and central Trailhead is at the Adams Street parking area from where you can go South towards the more technical areas (via Cross Cut and Middle Sister) or North towards the more cross country trails (via New Trail and Beaver Brook Way).

      Alternatively you can stay in the area around Adams Street Lot and ride the awesome trails such as Adams Lot Trail, Town Forest Trail, Sneaky Quickie, Optional Rocks, Sudden Impact, Humpback Rock, Deer Way, Right Turn Clyde, Do You Feel Lucky, New Trail, Bumblebee and Burial Bypass.

      If you are interested only in the big hit area on the NEMBA parcel, the closest parking is at the end of the Dunster Road cul-de-sac. Please do not park at the Wendy's.

      Have fun
