This 2660 acre forest offers visitors a natural diversity of flora and fauna accented with historically significant contributions of the Civil Conservation Corps (CCC). The focal point of the forest is located at 205 Westboro Road in Upton, where visitor parking, the main trail head and park information is available. One has the opportunity to survey the grounds and exterior of a number of CCC structures located at this site. Upton State Forest is a Carry-In Carry-Out facility, so we ask visitors to take home all their trash. While the forest is unstaffed, it is open to the public year-round at no charge. Trail users can enjoy numerous recreational opportunities for hiking, casual walking, horse back riding, cross country skiing and snowmobiling. Off Highway Vehicles (OHVs) are prohibited at the forest. Upton State Forest is part of the Miscoe, Warren, Whitehall Watershed Area of Critical Environmental Concern (ACEC).

Great dirt road, enough elevation change to make it aerobic and long enough to be fun. Lots of friendly people and dogs. Make sure you take a few of the side trails. Mammoth Rock is very interesting and Dean Pond is beautiful.

18 days ago

Made two loops, first just followed loop and park trails around, second followed swamp, mammoth rock, grouse, and whistling cave.

Park and Loop trails are nice and easy to walk around, great starting point, probably 3 stars on their own.
The real fun were the outer-lying trails, definitely 4 starts, would most certainly go back. Still fairly easy trails, mostly level terrain excluding a few areas, but much more enjoyable.

I enjoyed this trail for a family hike. Wide enough for us all to walk together. It is good for dogs too! A bit icy. Only one big hill st the end of the loop. Good hike fir hikers of all levels

A nice wide walking trail with hiking trail offshoots. I can see it being good for mountain biking and cross country skiing. The hill on Deans pond is the only short moderate part of all of the graded road parts, but all a nice walk. I would like to come back and explore some more of the single track side trails. Scenic this time of year!

First time unplanned exploration so this review is just based on a very small piece of the forest. We spent most of our time on the old cart roads but the few single track trails we found we're more of a 4 star rating. Whisteling Caves Trail was the highlight of this short hike. l look forward to exploring more.

This is a great walk through the woods. I definitely prefer heading toward the pond via Park Road to Dean Pond Road and back Loop Road, rather than the reverse direction. Park Road has lots of loose rock, making climbing more difficult.

Also, the climb up Park Road is almost a half mile long, with the corresponding half-mile descent. I prefer to do the steeper section during the first half of my hike. Loop Road consists of a lot of shorter ascents, with level stretches between.

Overall, this is one of my favorite hilly walks, and I come here often.

This is one of my favorite 3 mile walks. Nice & shady on hot days. Beautiful foliage in the fall. Be careful after a hard rainfall, as the many cobbles and rocks on Park Road can be slippery. Pretty scenery, especially at Dean Pond.

Nice, no litter but a few dog poop bags ! Why pick it up only to leave plastic bag behind ? Otherwise really enjoyable. Whistling Cave trial was my favorite. Will definitely be back.

I am a veterinary student in Grafon, MA and love bringing my dog here for study break walks/hikes. Mammoth Trail and Whistling Rock Caves are our favorites when we are feeling a bit adventurous. Taking a walk down to the pond is also an easy relaxing trip.

Very nice winter hike. I altered the route and was glad I did. Instead of coming back on Park Loop Road, I took the Whistling Cave Trail. Besides being able to see the Whistling Cave, this trail was much less traveled and has a more rustic vibe. There are a few small brooks you have to cross when the water is higher . There are some beautiful rock formations there too! PS wear some micro spiked if going in the winter. There are some icy areas.

Wonderful spot . Took Middle Road to Dean Pond .Nice shade .Awesome rock structures. Pond is lovely. Accidentally came back on Park Road which is less scenic and less shade. Plus 1/2 of Park Road is almost all uphill . Nice dry trails. Would come again

Explored the main loop of the forest and checked out the whistling "cave". Easy, well-marked hike recommended for those with dogs or small children.

Gorgeous day to be hiking, and a lovely park to do it in! A little muddy in some spots, but overall great trails and well-marked.

Nice hike. Two beaver huts.

I have hiked here for years. A few years ago they made it on leash for dogs which I personally think is great for the main trail which is the one most travelled. I take some of the small out of the way trails and will unleash there. I maybe run into a few hikers a few times a year on the off trails. The big loop is wonderful to run on and isn't horribly tough as long as you go right at the main fork. I made the mistake the 1st time of taking the left in the fork and ended up walking up 'that hill'. You only make that mistake once lmao Quiet area but can be a bit buggy during that time of year or towards dusk. Still one of my favorite places to hike though.

great to take dogs and Mountain biking

Beautiful day for a hike. The last mile was tough. Almost enough to make it "moderate"?

Terrific! Can't wait to return.

Beautiful trails. HUGE hill at the 2 mile mark that I was NOT ready for. Next time I will do it in reverse and start out going to the left. Dean pond is gorgeous. Worth the effort

My first time out. Much harder than I thought! HUGE hill at the 2 mile mark. Turned into a part hike. At first, a dragonfly landed on me and I thought I had a chance..... Nope. All in all.... A good experience. Will come back now that I know what to expect.

Use the loop trail 3-4 times a week. Love it. Peaceful, clean, easy walk. Took Nuthatch Trail with my husband last weekend. It has some spots with hills...great workout. Also snow shoe there in the winter. Well marked....maps and parking available. A GREAT SPOT

Took my 8 month Viszla/Pit mix on 3.3. Finn had a great time. Nice size trails and peaceful. Going back to checkout other trails.

Excellent trails to walk with dog. Wide, so less likely to get ticks on you.
Note: This park is Dogs Must be leashed. I was walking with my dog (leashed) on Sat. 8/9/14 and a German Shephard came out of nowhere and attacked my dog (we were on Whitehall Rd trail). The attach drew blood! I was hollering and quite scared. Two joggers came by about 3 minutes later and the dog resumed his run with them. Neither of these 2 men called the dog over or acknowledged that their dog had attached mine. Boy was I and am I totally pissed. This is very ignorant behavior. Please beware of this German Shepherd off leash with Runners.
