Not very big, but adequate. About 5 miles from the Monument Valley Tribal Visitors Center. Nice grassy playground. Fenced dog run but be aware that smaller dogs can easily go under the gate. Staff is nice and friendly. My only complaint is that while the bathrooms are clean and have ADA showers with seats, there is no ramp to get into the building itself. The step isn’t big, but a person in a wheelchair will have difficulty without assistance.
