Hirundo Wildlife Refuge is a 1.7 mile lightly trafficked loop trail located near Old Town, Maine that features a river. The trail is good for all skill levels and primarily used for walking, nature trips, and birding.
Really nice area, views of the river and some beautiful little spots. Not a strenuous journey by any means. Trails are pretty well marked and maintained. Definitely a nice little place to check out and walk around. It's entirely maintained through volunteers and contributions, a great place to support. I was just saying to myself the other day that I never see Hirundo mentioned anywhere for walking, birding, wildlife viewing, I think maybe even fishing. There is a small store where they sell bird feeders and other things of that nature.
