Coquille Myrtle Grove State Natural Site is a small state park on the South Fork Coquille River between Myrtle Point and Powers that combines day-use recreation with preservation of Oregon myrtle trees. Created in 1950 after Save the Myrtlewoods donated the land, the 7-acre site offers a swimming hole, sandy beach, fishing access, parking, picnic tables, and restrooms. It protects a remaining stand of slow-growing Oregon myrtle, also known as California laurel or Pacific myrtle, a hardwood long prized for furniture and specialty woodwork. The site is especially important because many larger low-elevation myrtle groves along the Pacific coast were cut, though this riverside park is occasionally subject to flooding.
