If you're looking for a challenging ride that isn't too technically difficult but more of a bumpy ride, you'll love the ATVing at Somerville Lake. The area with the ATV trails is very undeveloped, somewhat eroded and if it has been raining, you will find a lot of standing water in the lower lying areas.
The best thing about Somerville Lake is ATVers are allowed to ride anywhere within the designated ATV riding area and the area is open all year around and no permit is required to ride your ATV. This undeveloped terrain makes for a fun ride, be sure to wear all your safety gear as with all rough and rugged terrain, your ATV or someone else's can roost up a rock or other debris and if the debris hits a chest, leg or hand - it can really sting. Simply wearing proper riding gear for your ATV will eliminate this problem.
At present, only 3 and 4 wheel ATVs are allowed on these trails. You will also be sharing the ATV trails with motorcycles. If your ATV won't fit through the pipe rail fence at the entrance of the ATV trail, you simply can not ride it there. Since you're sharing these trails with other riders and the trails are not clearly marked, do exercise caution. This ATV area is only open from dawn until dusk and there is no currently no camping allowed.
No matter what your ATV riding skill level, you will find a lot of challenges at Somerville. If youare a newer ATVer, there are easy to navigate paths by the trailhead. If you're a more seasoned ATV rider, you will thoroughly enjoy the ATV trails as they go further down as the terrain gets a little more eroded and will have a lot of inclines and dips for you to test your skills upon.
Maps are available, and even though this is not a large ATV riding area, since the terrain is so raw, it would be a good idea to get a map to insure you don't get lost or on a trail that is too difficult for your riding experience level.
