Very nice park, conveniently located close to the city, and but far enough away that you can actually find some solitude. The park is filled with interesting glacial formations, if you are a geology buff. Many trails to choose from, ranging from very easy to moderate. None of the trails are especially challenging, one needs to go off the beaten track for that. Most of the trails are clearly marked and they are all well maintained. There is a map of the trails with descriptions posted on their website, along with allowed uses of each trail. The trails interconnect well, so it's possible to tailor your hike to the length you would like just by choosing the right combination of trails. Be careful with this though, because if you are anything like me, you can zone out in the tranquility of it all before you realize that you are now about 9 miles from your car (going back along the trails, that is). Yeah, I take spontaneous 18 mile hikes.
I've hiked all of the trails in every season, so I'll give a quick rundown based on my personal opinions:
Bird Song: great for families, easy and short trail with some hills, but nothing major. Chickadees will eat sunflower seeds or bird seed out of your hands. Lots of chipmunks and red and gray squirrels. Connects with Swamp Trail.
Swamp Trail: Pretty cool, short loop. Has a boardwalk through a swamp that has a ton of wildlife (turtles, frogs, birds, etc.) and a bridge or two. Connects with Bird Song and Quaker Loop.
Quaker Loop: easy loop around Quaker Pond with wooden bridges. Connects with South Meadow.
South Meadow: similar to North Meadow, minus the wooded areas. Always found this trail kind of boring, but like North Meadow and Grasslands, it is nice in the spring.
East Esker: My personal favorite. About five miles with a detour near the water tower to an "observation point". Lots of wildlife. I've personally seen deer (and LOTS of them), raccoon, fox, woodpeckers, and skunk among others. It is also the most challenging trail at the park, with many hills and elevation changes. The trail also passes through the highest point in the park. Connects with North Meadow.
North Meadow: passes through woods and a meadow with tons of wildflowers, birds, and butterflies in the spring.
Grasslands: A very easy loop which is relatively flat. Nice in the spring when flowers are blooming and there is a plethora of song birds and butterflies. Links with the Devil's Bathtub trail. The section close to Clover Street can be a buzz kill though.
Devil's Bathtub: a popular loop that passes around, you guessed it, Devil's Bathtub. Get ready to climb a big set of wooden stairs on this trail. Connects to the West Esker trail.
West Esker: a fun, hilly trail that skirts a bit of Hundred Acre Pond and is home to Cardiac Hill.
Pinewoods and Fern Valley: kind of similar in length and terrain, they are nice, short loops through woods, but they are kind of isolated on the north side of the park. You can get to them from other trails by crossing Hopkins Point and Canfield Roads, respectively.
I think that covers them all. I think I've spent way too much time hiking through Mendon Ponds. read more
