Quintana offers six miles of natural sandy beach with free vehicle access and parking. Quintana Beach County Park offers RV sites, cabins, restrooms and showers, a playground and an elevated boardwalk that leads to the beach. The park also has hiking trails and a great lighted fishing pier. From Memorial Day weekend through Labor Day weekend there is a $5.00 parking fee per vehicle collected at the entry gate to the park for day use access of the park and pedestrian beach. Registered overnight campers are exempt.
As a natural beach, Quintana is maintained by tides and weather. At any given time, there may be driftwood, seaweed and other plant life on the beach. These materials provide nourishment and stability to the ecosystem. The beach is raked in cases of excessive build-up of seaweed or debris. The island is home to many birds and butterflies that can be observed at the Quintana Neotropical Bird Sanctuary.
