Summers can be hot and humid. During the winter you can also ski the trail, specifically the Miller’s Woods part of the trail.

We hiked the trail on July 1 and we got to see the end of the spring wildflowers. We just missed seeing all the lupine in bloom. It was hot and humid during our hike so if you are planning to hike in the summer, earlier is better.

Hiking Details of the Paul H Douglas Hike

The trail starts right at the Paul H Douglas Center for Environmental Education on a flat and wide open trail. The trail passes over a series of bridges and boardwalks over the pond and through Miller’s Woods.

This is a great place to look for birds and beaver.

After crossing the bridge, the trail winds through the forest. There are several places where there are multiple trails going off the main trail, but the trail is generally easy to follow. After a short distance, you can make the decision to hike the short woods loop or head to the beach. There is a short rise where you can get views of the ponds.

The next part of the hike goes through a black oak savannah. This area is old sand dunes that now have plants and trees growing on them. Part of the trail is sandy, but it is generally an easy walk. This area has the most wildflowers of the hike.

There are very few black oak savannahs in the world, so this is a special part of the trail.

After about 1 mile, the trail becomes much more sandy and follows along the edge of some wetlands and ponds. The sand in this section was much deeper and more challengings to walk in. The trail also gets narrow in several sections around the last pond before opening up in the dunes just before the beach.

The trail passes just a short distance through the dunes before ending at the beach. This is one of the quieter and prettiest beaches in the park and even in mid-summer there were only a few other people on the beach. It is possible to swim in the water although it is very shallow for a while.

This is also a great place for a picnic.

After you enjoy yourself at the shoreline, retrace your steps back to the parking lot.
