The majority of hotspots have restrooms and visitor centers open during business hours. Visitor Centers provide information, check lists, maps, and displays with staff available to answer questions. Most hotspots are open dawn to dusk, except those operated by cities, which are open during business hours and closed one or two days a week, usually Sunday and Monday. National Wildlife Refuges and State Parks are open 7 days a week from dawn to dusk; most are closed at night, with a few exceptions. Currently most birding hotspots have an entrance fee of $5 to $10 per person, but some offer free entry. There is no card that covers entry to all hotspots. Different systems offer different cards. Enquire at the Visitor Center.
