🌿 What You’ll See on the Lost Valley Trail

One of the best things about the Lost Valley hike is how much variety it offers in a relatively short distance. Along the way, you’ll pass towering rock walls, lush forest scenery, and several notable landmarks.

Highlights include:

Eden Falls

Eden Falls is the first and most recognizable waterfall along the Lost Valley Trail. Located a short distance from the trailhead, the falls cascade over a rock ledge into a shallow pool below and are especially impressive in spring after periods of rainfall. A natural rock bridge sits just downstream, making this area one of the most photographed and popular stopping points on the hike.

During drier conditions, Eden Falls may slow to a trickle, but the surrounding rock formations and shaded setting still make it a worthwhile destination and a good place to pause before continuing farther up the trail.

Natural Rock Bridge

Just beyond Eden Falls, the trail passes beneath a natural rock bridge formed by years of water erosion. The bridge spans the creek and creates a shaded corridor that feels almost tunnel-like as you walk beneath it. This unique formation is one of the defining features of the Lost Valley Trail and a natural transition point as the hike begins to climb farther into the hollow.

The area around the natural bridge is a popular place to stop for photos, especially when water is flowing beneath it. Even during low water conditions, the scale of the rock walls and the sense of enclosure make this section of the trail memorable

Alum Cave

Alum Cave is a massive bluff overhang and one of the most striking features along the Lost Valley Trail. Located beyond the natural rock bridge, the wide alcove provides a shaded resting spot and often serves as a natural turnaround point for many hikers. The scale of the rock wall and the cool, sheltered setting make this a memorable stop, even for those who don’t continue farther up the trail.

During periods of higher water flow, a third seasonal waterfall can be seen cascading near Alum Cave, adding to the dramatic feel of the area.

Cobb Cave & the Hidden Waterfall

Beyond Eden Falls and the natural bridge, the trail continues uphill to Cobb Cave, a massive rock overhang that invites exploration. While the main cavern is easy to access, adventurous hikers can venture deeper.

Inside the cave system, those willing to crawl and navigate tight spaces may find another waterfall, estimated at around 35 feet tall. If you plan to explore beyond the main cavern, bring a flashlight or headlamp and proceed carefully.

Waterfalls on Lost Valley Trail (What to Expect by Season)

Rain and snow play a major role in how the waterfalls on Lost Valley Trail appear throughout the year. The trail features three waterfalls, but their size and visibility can change dramatically depending on recent rainfall and seasonal conditions.

In spring and after heavy rain, Eden Falls is usually flowing strong, the seasonal waterfall near Alum Cave is often visible, and the upper waterfall inside Cobb Cave may be active as well. This is when Lost Valley feels at its most dynamic, with water moving through the hollow and across the rock formations along the trail.

During drier periods, especially in late summer or fall, water levels may drop significantly. Eden Falls can slow to a trickle, while the seasonal waterfalls near Alum Cave and inside Cobb Cave may disappear altogether. Even when water flow is low, the rock formations, caves, and shaded corridor still make the hike worthwhile, offering a very different but equally scenic experience.

Because conditions can change quickly, recent rainfall is often a better indicator of waterfall activity than the season alone.

Best Time to Visit Lost Valley Trail

Spring is the best time to hike Lost Valley Trail if waterfalls are your priority. Seasonal rainfall dramatically affects water flow, and during dry periods the falls may be reduced to a trickle.

• Best months: March–May
• After rainfall: Waterfalls are most impressive
• Summer: Shaded but waterfalls may slow
• Winter: Quiet, but icy conditions possible

Gear Recommendation

Because Lost Valley Trail includes stream crossings, uneven rock, and a few spots where you’ll want both hands free, a comfortable day pack makes the hike more enjoyable. We typically carry water, a light layer, snacks, and a camera, and having everything secure but easy to access is especially helpful near the waterfalls and caves. A lightweight, well-fitting day pack like those from Cotopaxi strikes a good balance between comfort and function, and it’s become one of those small gear choices that quietly improves the overall hiking experience.
