Open Land Conservancy has eight nature preserves, totaling 380 acres. Seven are in the Great Valley area in western Tredyffrin Township. Another 90 acres in conservation easements are also protected, bringing the total land preserved to nearly 470 acres.

The preserves are open to the public, subject to posted guidelines. Dogs must be leashed and picked up after.  Well maintained trail systems provide hiking, birding, cross-country skiing and fishing along Valley Creek.  Guided walks and educational programs are offered to members, school groups and scouts.

Report a safety, repair or dog off leash issue in a preserve.
