The Bluff View Trail derives its name from having a handful of exceptional scenic viewpoints that overlook the Meramec River and surrounding countryside. There are some nice ups and downs on this route to get the legs working, but there are a few rocky and rooty sections, so mind your footing. There are a few bikers on this route, so you may want to keep your earphone volume to a minimum so you can hear them coming.

This is an 8 foot (2.4m) wide trail made of crushed stone that follows the Meramec River between Glencoe and Sherman Beach. The suburban trail has coined the nickname 'Zombie Road', due to its supposed supernatural activity. The trail provides wonderful views of Bluffs Forest and the river.

The most popular trail in Castelwoood State Park! The trail is fun for intermendiate to advanced riders and a good learning opportunity for beginners. The first half of the trail is flowy hardpack which turns into a steep rooty downhill run and a rutted climb known as Cardiac Hill. Its also convenient to loop in the Roller Coaster and Lone Wolf trails as you go round this trail.
