Our Public Conservation Areas are open year-round from dawn to dusk, and free to the public (though of course, we encourage you to make a donation if you enjoyed yourself!).  These areas provide a variety of different experiences for visitors, whether you’re interested in trekking up the hills at Round Ball Mountain or Drowned Lands, or watching the monarchs at Greenport Conservation Area (which includes an Accessible for All trail for individuals who use a wheelchair).

We use counters to gather data about trail use.  This helps us to better understand and manage our trails, and is very important when applying for grants and other funding.  To learn more about the TRAFx trail counters we use, please click here.
