Hiking the Lost Valley Trail in Arkansas

The hike is more than just a leisurely walk through the forest. It includes intersecting trails that take you on an adventure of discovery to some beautiful places with scenic overlooks, and it ends with an incredible 200-foot bluff shelter called Cob Cave and Eden Falls.

The impressive rock formations, bluffs, caves, and waterfalls are the best parts of hiking in Lost Valley. Eden Falls is a 53-foot waterfall that is a sight to see in the spring after the snow melts and there is spring rain.

And, if you’re up for an off-the-beaten-path adventure, there is another cave, Eden Falls Cave, further along the trail accessed along the steep stairs passed Eden Falls. The trail ends at the cave’s opening, but there is a 25-foot waterfall inside. You definitely want headlamps and caving knowledge to enter this part of the trail.

It takes about two hours to hike leisurely and explore the rocks and waterfalls along the main Lost Valley Trail. The majority of the trail follows Clark Creek.

Lost Valley is a fun trail to hike!

Best Time of Year to Hike Lost Valley Trail

Hiking the Lost Valley Trail can be done year-round. However, spring is the best time to see Eden Falls and the Natural Bridge flowing more water.

Hiking in the Ozarks during the fall, late fall, and early winter is always a treat. After Thanksgiving, there are fewer crowds. Weekends are busy since this is such a popular family trail.

Lost Valley Trail Arkansas Camping

There is excellent camping in the Buffalo National River Upper District.

Steel Creek Campground – Steel Creek Campground is another great option close by for tent camping within Buffalo National River. There are flush toilets and running water seasonally from mid-March through mid-November. Campers can make reservations ahead of time on recreation.gov.

We have camped at Steel Creek a few times and love the easy access to trails!

Buffalo Outdoor Center – this is where we stay with our Aliner camper because the Buffalo Outdoor Center Campground is RV, trailer, and camper-friendly. They also have great restrooms, hot water, wifi, and full hookups. The staff is super friendly too!

What We Wear Hiking

Cob Cave

Since we hiked during December, we wore layers to accompany the temperature swings, which were around 30 degrees Fahrenheit in the morning and 65 degrees in the afternoon.

Pablo wore his go-to Patagonia R1 fleece layer, Kuhl hiking pants, and Oboz hiking boots.

I wore my go-to Oboz hiking boots and used my favorite Kavu day-pack!

Final Thoughts on the Lost Valley Trail Loop

We hiked the Lost Valley Trail in early December and were in awe of the Cob Cave bluff shelter! It was huge, and there was room to explore.

The Natural Bridge and Eden Falls waterfalls were just a trickle during early December, but we saw the beautiful emerald pool at the base of the falls.

We hiked during mid-week, and there were no crowds.

We also saw one bull elk in the fields along Highway 43 (so cool).

    Been hiking this trail 25 years now and still going back. I remember when the grass would brush your legs due to the trail being no different from a deer trail many years ago. It still brings me joy everytime I return BUT PLEASE people STOP carving your names in the BIG beautiful Beech trees.

    • Ashlee Fechino on March 10, 2022 at 6:37 pm

      Hi Tucker – Thanks for commenting and sharing what the trail was like 25 years ago. That is really special and we appreciate you sharing. We agree – it is so important to Leave No Trace!

  2. Ava on March 9, 2022 at 7:04 pm

    I love seeing waterfalls on a hike. I love the idea of a waterfall in the cave but I’m not sure I’d be willing to crawl to see it!

    • Ashlee Fechino on March 10, 2022 at 10:34 am

      Hi Ava – haha, we totally understand about the cave part. I think it is better to go with someone who has gone in there already. Have a great day. Thanks for reading.

    Woooah this is really cool Ashlee! I love it when a short hike managed to pack in soo many cool sights. The Cob Cave bluff shelter is really impressive and I am always keen to visit waterfalls. It would be really cool to see them in the springtime when there is more water gushing over those rocks!

    • Ashlee Fechino on February 19, 2022 at 2:02 pm

      Hi Josy! Thanks for reading our article. The bluff shelter is jaw-dropping. You will love hiking here!
