Limitless Adventure: Greenfield State Park

Hey guys I'm Ian and this is Limitless Adventure! We're going to be bouncing around from state park to state park going on a series of adventures.

Starting today we're at Greenfield State Park. We've got a bunch of activities planned let's go for a hike to get things started.

We're going to take the hike on the Hogback Trail, about a mile loop and so far the trail is super easy and has such a scenic view.

Just finished our loop around the pond. A great warm-up for the day, so I'm going to run back grab a bike go for a tour the campground.

I just finished up my tour of the campground and worked up a bit of a sweat.

Going to go grab the paddleboard and hit the water.

I'm out here on Otter Lake which is a pretty big lake.

The nice thing is, if you come early enough in the season, you might just get that place to yourself.

Well it was great take it out on the water. First time for the year!

I'm going to pack the board up and head back and warm up by the fire.

Not bad for the first adventure of the year, and they'll be many more.

Time to get a S'more stick and I'm going to kick back relax and enjoy the night.

I'm Ian and this is Limitless Adventure!
