Visitors who buy an annual pass to Arizona's state parks will now get an added bonus: a free subscription to Arizona Highways.

Starting this month, the magazine is partnering with Arizona State Parks and Trails to offer a free one-year subscription to those who buy either a standard or a premium annual pass.

"This is part of an amazing partnership we have with Arizona Highways," said Sue Black, executive director of the parks department, in a news release. "When you visit the parks, you see the rich diversity of the state, and when you read the magazine, you can experience even more of what makes Arizona truly special."

A standard annual pass costs $75, plus a $7 handling fee, and covers day use at all state parks, except weekends and state holidays during peak season at a handful of the most popular parks. A premium pass costs $200, plus the $7 fee, and allows access to any park on any day of the year. Both passes allow entry for up to four people in one vehicle.

The free subscription will be available everywhere passes are sold. For more information about the passes, click here.

Among the highlights of Arizona's state park system are Kartchner Caverns State Park, which features a spectacular network of limestone caves; Oracle State Park, whose 15-mile trail network is now open every day of the week; and Boyce Thompson Arboretum State Park, the largest and oldest botanical garden in the state.

"There is such natural synergy between Arizona Highways magazine and Arizona State Parks and Trails," said Win Holden, publisher of the magazine. "When circumstances prevent an in-person visit to a state park, you can still get a healthy dose of spectacular landscape photography and the state’s best hiking and scenic drives inside the magazine each month."
