Saturday, June 1 is the 21st annual National Trails Day. Lace up some sturdy shoes, grab a hiking stick and head to a Texas State Park near you to join a guided hiking tour or hit the trails on your own. Dozens of state parks will be offering guided nature hikes - from short, family-friendly hikes geared toward beginners to more strenuous treks of up to seven miles. "National Trails Day is a great time to showcase the beauty and diversity of the trail systems in our more than 90 state parks," says Karen Blizzard, assistant director of Interpretive Services for Texas State Parks. "Spending time on the trail, whether hiking, biking, or nature viewing, provides happy memories, good health, escape from stress, and cherished time with friends and family. Stewardship and volunteering also are a big part of National Trails Day, and we encourage everyone to get involved with trail maintenance and volunteer projects at state parks near them," Most of the National Trails Day state park events are at no extra charge, but regular Texas State Park entrance fees will apply. As always, children ages 12 and younger receive free park admission. To check park fees that apply to your favorite state park, visit www.texasstateparks.org. If you would rather lay down the hiking staff down and grab a fishing pole, June 1 is also the annual TPWD Free Fishing day in any public water in the State of Texas. Fishing inside Texas State Parks has always been free. Once you've paid the park entrance fees, no one needs a fishing license or stamp, whether freshwater or saltwater, adult or child, as long as they are inside the state park. This applies to fishing from the bank, a pier, river or creek fishing, and fishing from a boat. You can even wade fish in coastal state parks along park property. Bag, length limits and other regulations still apply. You can enjoy the Free Fishing in State Parks program at more than 50 state parks, and at numerous Wildlife Management Areas across Texas. Check the state park near you to see what special events such as fishing derbies and "Learn to Fish" seminars. Some parks provide loaner equipment and bait: just call ahead to ask.
