We loved the Big Bend area and are planning a trip there next Fall. It's a bit far for a day trip though. We haven't been to the Oklahoma Fort Smith area or Tahlequah. We've enjoyed biking and hiking the Talamena Highway many times and Beaver's Bend State Park is great for canoeing but has become overrun by it's popularity. We enjoy secluded areas with hiking trails and kayaking opportunities. Oklahoma has many beautiful areas we have not begun to explore. Thanks for your info!
