AvinaNatural Reserve
The Avina Nature Reserve Access (ANRA) card allows you, your passengers, and your vehicle to enter the Avina Nature Reserve at Amber Falls. Daily, weekly, monthly, and annual cards are available. These can be purchased for a fee of $10, $25, $40, and $60, respectively, at the visitor information center located at the park's entrance. Cards can also be ordered online at www.avinapark.com. Online orders will be delivered to your address within approximately a week of your order. As a special courtesy to annual card holders, we currently offer a 50 percent discount on fees charged for facilities and services including camping, swimming, boat rentals, and fishing equipment rentals. Please note that visitors are required to make all payments at the time of purchase using cash or a personal credit card. Please note that proof of purchase of an ANRA card is not sufficient to enter the park; the actual card is required. Once on the premises of the Avina Nature Reserve, please make sure your card is in an area of your car, such as on the dashboard, that is clearly visible from the outside. Also, since the ANRA card carries the license plate number of the vehicle registered with the Avina Nature Reserve, it cannot be used with another vehicle.
