Travel Policy

Under the Moving Maine Forward plan, Maine has shifted its COVID-19 travel policy to automatically exempt all states, unless a state is otherwise determined by the Maine CDC as being high risk. If one or more states see a spike in cases of highly contagious COVID-19 variants, Maine will apply its test or quarantine requirement to travelers to and from that state. The Maine CDC will publicly announce any such states when they are identified. 

Facial Coverings & Physical Distancing

Maine updated its public health guidance to remove the requirement that people wear face coverings in outdoor settings except where it is difficult to maintain physical distancing. Face coverings are still required for indoor public settings, and there are no changes to Maine’s physical distancing requirements at this time. The change follows updated guidance from the U.S. Centers for Disease Control and Prevention, including the use of face coverings in outdoor settings.

When visiting any of the lands or gardens of the Preserve, please:

  • Always carry a facial covering and be prepared to wear one when physical distancing cannot be maintained.

  • Stay at least six feet apart from other visitors and staff.

  • Step off trails and paths to let others pass.
