We are lucky enough to have some nice trails to ride within a 1-1 1/2 hour drive. Picture on right was taken on Flat Rock Trail at Bell Cow Lake during one of our winter rides.  (See description of Bell Cow trails below.) Seminole, Sportsman Lake:   Trails here are rocky, a little hilly.  Several creeks/streams and a few ponds.  Mostly wooded.  Shoes or easyboots are definitely needed unless your horse has very tough feet and is accustomed to this type of terrain and if you are just going to walk.   These trails could be considered "challenging", but are not like riding in mountains.  A nice place to take young/inexperienced horses.  They will see lots of things and will have to pay attention to where they are placing their feet.  It doesn't take them long to learn to stop being silly and start concentrating on what they are doing!   Best to go with someone familiar with the trails, if you can, for the first few times.  They are marked, but it may be confusing in places if you haven't been there before.  2 different areas to ride, both are out and back.  The 2 areas probably total about 25 miles (round trip).  The south trails are newer and a little less worn.  The north trails have more places for the horse to drink.  Note that I have not ridden there since fall of 2009, so not sure what condition the trails are currently in. There is parking for day riders and also several campsites with picnic tables, water and electric hookups.  No reservations, first come first.   Permanent bathroom with flush toilets and a shower.  (The facilities are not fancy, but do have hot/cold water.)  A dump station is located across from the bathroom.  Stillwater, Lake Carl Blackwell:  These trails go through open meadow areas and wooded areas.  A bit more wooded than open.  Even a stretch with mature pine trees.  Some small hills/dip and creek crossings.  Be aware that these areas can get slick when wet due to the clay content of the soil.  There are 50+ miles of trails with more planned.  There is even a driving trail!  There are some CTR rides and endurance rides held there yearly.  Several organized rides and/or 'poker rides', too.  Trail maintenance is done primarily by riders/volunteers & some by park ranger.  I'm told that trails are in pretty good shape at this time (Oct 2010), but haven't been there this year.  Maps are available.  The campground is a large open area and has a few sites with electric hookups.  Porta-pots, manure dumping area and horse wash racks are available.  There are even a few horse pens.  Campsites are roomy so that you could set up small pens or picket lines for your horses.  There are water faucets scattered around the camp ground, so you can get water for your horses.  Chandler, Bell Cow Lake: 2 trails, both are out and back.  The shorter loop (Flat Rock Trail), 10  miles,  is a mix of open and wooded with a very short section on a gravel road.  The longer loop (Redbud Trail) is about 22 miles round trip.  It includes  about 1/4 mile of gravel road.  Other than that, mostly soft footing with occasional rocks.  It travels through woods,  below the dam and through the edges of a couple of campgrounds (Areas A & B).  There are picnic tables there and restrooms.   Another picnic table at about 11 miles out.  Trails are an even mix of open and wooded.  Within the past 2 years, nearly all of the trails have been widened and improved.  Several new culverts have been placed in areas where previously the crossings were boggy and/or dangerous.  Some work done as recently as November 2011.  New, permanent trail markers have been installed and you should be able to find your way around without any trouble.  Trails are maintained by volunteers.  I highly encourage volunteers to "adopt" a section of trail to maintain.  (No official trail adoption program in place--done on your own.) The campground is nice, with lots of improved sites (water and electric hookups), gravel pads, picnic tables and grills.  Picket poles at some of the sites.  Nice permanent bathrooms, swimming beach, etc.   Manure is to be bagged and placed in designated dumpsters.  Dogs need to be on leash or else confined.  Prague Lake:  Nice, well maintained trails.  Easy terrain with a few steep creek crossings.  (Dry creeks)   A single main loop (red/pink) that goes around the lake.  However, there are several loops (blue) that go back and forth off of the main loop and eventually tie back into it, so you can see different trails.  Not a lot of miles in total.  If you do the entire pink loop, including the 1 mile across the road from the campground, you will have done about 7.7 miles total.  By doing some of the blue loops, you may add a short distance.  Mostly, it will just be some different scenery.   There are several "obstacles" set up on trail for those who would like to practice.  Such as a "wooden bridge" (fake crossing), wood framed steps, a wooden teeter totter, 2 tall poles with a rope draped between them, a couple of mailboxes, and something I don't know the name of...I call it a ring-around-the-rosey.  The trail challenge riders will know what it is! Campground has some elec. hookups, pavilion, some pens made with corral panels, permanent bathrooms with showers.   All in all, a nice friendly feeling place to ride.  .    Cedar Lake, Ouachita National Forest:  OK, so this place is a little more than 1 1/2 hour away!   But, it is one of my favorite places to camp and ride.  LOVE.  IT!  The pictures on the "Cedar Lake" page were taken during several different trips there.  Beautiful country, challenging trails, the best campground anywhere.
