Trail Description
About this trail
This trail system is mostly single track, and varies from long flat stetches on the Meremac River bottoms, to some short hill climbs and descents as you get away from the river. If you start your trek on the bottoms, you can head westward along the river until you find a railroad bridge which you can ride under (Cedar Bluff loop/Blue Ribbon Loop as some like to call it). This will take you to a loop trail that is quite fast and fun up in the hills. When you return on the bottoms, you can then hit the trails around the parking lots (there are several). Most are well marked and well ridden singletrack. Nothing especially challenging, but all quite enjoyable for an afternoon of riding. Castlewood State Park has a website with a good map of the trails. This is a hiker/biker shared system and it can be quite crowded. 15.5 total miles of trail in the park.

Review: As has been stated there is a wide variety of trails here. You will struggle to find your way around without a map even though there are numerous trail markings. Some sections are just rocky fall line runs (ie. Lone Wolf start) but much of the trail winds through the woods without getting too steep. Flat trails exist along the river. I saw how heavily used these trails are by choosing a cool, fall Sunday to ride.

Review: trails for every skill level. fun place to ride. beautiful views. only drawback is it is the most crowded place in the area. also tends to get the most damage to the trails, ie. widening and ruts. ride early and you'll have a better time.

Review: Castlewood is the first trial system I ever rode as a Mountain biker. I fount that is had sections that are very beginner friendly and other section that are extremely challenging. The river scene trail is the easiest trial being almost all flat wide track and a half. Then You come to Lone Wolf. Lone wolf climb has a steep climb to start off and then into some rolling rocky climbs and a fast tight switchback filled decent with one log to make it over at the end of the down hill. There is a creek crossing that is fun in the summer months for sure! I am most fond of the Grotepeter and rollercoaster section of the park They are good all around trails for any ability level in my opinion, I still find sections that challenge me every ride. Over all a very fun place to ride, just beware that when the weather is nice on the weekends this park is very popular and can become quite crowded so be on the lookout for other riders and hikers.

Review: Look up reviews on the other Castle wood park. Great mix of trails easy to tough Loads of trails to choose as well and plenty of people incase you get in trouble

Review: Another great place for a mix of trails. You can find beginner trails and also a few sections that can be a challenge for more experienced riders. I think the harder part is "Gopher Ridge". It can provide a couples hours to a full day of fun. Make sure to bring bug spray!!! Ticks and Chiggers

Review: VERY busy trail system I rode this week while visiting family - but good variety for rides. Everything from extremely fast and sandy two track along the river bottoms to great climbs and quick rocky downhills. If you can avoid the crowds you can have a great time.

Review: This pasted weekend was awesome to be out ride and we could not have been on a much better trail. It was a mixture of easy single track with some hard technical areas thrown in.

Review: A very nice park to ride through but to be completely honest I would rate the trails a 5-6/10 (the scenery gives the park 4/5 in my book). That being said, I still recommend giving Castlewood a couple tries if you haven't been there before. The trails do have some moderate climbs and downhill section with areas that require some technical skill...I just wish there were more areas for jumps and skill areas with log rides, etc. There is one downed tree over a deep trench down along the river trail (past "the narrows") that is fun to ride, but that's about it as far as skill areas go. Fantastic scenery in the park and great for riding every once in a while, but personally I will stick to the more technical trails around St. Louis for the majority of my riding.* Review edited 8/22/2010
