13. Have a BBQ and Hike at Douglas State Forest

No reservations required for this fun day at a local state park! Douglas State Forest has a ton of great warm weather activities to craft a perfect Father's Day on the cheap. Here are some ideas: Walk the Cedar Swamp Trail on a meandering wooden walkway through a bog; check out the 2.2 mile Coffeehouse Trail Loop (easy and flat walk through pine forests and over foot bridges;) bring the burgers to have a cookout on the beach (plenty of picnic tables and grills available;) bring the boat, lawn games, and your bathing suit! Just don't forget Dad! $10 per vehicle or free with a state pass.
