Here are some of my favorite trails in the state in no particular order:
Emerald Park - North Little Rock
Emerald Park has trails that connect to the River Trail in two places. The park has amazing views of Little Rock and the Arkansas River. During and immediately following heavy rains, numerous spectacular waterfalls form along the bluff.
Fourche Creek - Little Rock
Fourche Creek, as I said in dozens of speeches over the years, "is an amazing and largely unknown educational and recreational resource located in the heart of Little Rock." Depending on your floating style, over 20 miles of the stream are floatable. The stretch upstream of Interstate Park can be floated in the dead of summer when many other rivers in the state are too low.
Pinnacle Mountain State Park
While the East and West Summit trails are the main attraction in the park, the less trafficked Quarry Trail, Ouachita Trail, and the water trail along the Little Maumelle are very scenic as well.
Petit Jean State Park - Seven Hollows Trail
The Seven Hollows Trail is my favorite trail at Petit Jean, which is probably my favorite state park in Arkansas. The trail passes by multiple interesting rock formations and a small waterfall. This area of the park suffered a bad wildfire many years ago and for a long time the lack of vegetation made me feel like I was hiking in Utah instead of Arkansas.
With three incredible trails underground and additional ones above, Blanchard Springs offers some unique and spectacular views along trails that vary from short and easy to long and somewhat difficult.
