Pros & cons
PROS
- Naturally cool microclimate under shaded sandstone—great on hot days
- Two access points make for an easy, flexible loop right from the main overlooks
CONS
- The actual tunnels are closed, removing the trail’s namesake feature
- Short stair climbs and slick rock after rain aren’t great for limited mobility
- Limited views compared to nearby overlooks and loops
Park at Grandview’s Main Overlook lot; one trail end is off the paved walkway to the overlook, the other near the baseball diamond/playground.
Tunnels are closed—do not enter. Expect steps, uneven footing, and slick sandstone after rain; there are drop-offs just off the trail.
Overview
A short, character-packed walk in Grandview, this trail is all about cool sandstone, deep shade, and rock features. It’s officially 0.5 miles one way or commonly done as a 0.6-mile loop. Expect short stair sections, uneven rock, and a pleasantly cool microclimate even on hot days.
What You’ll See
You’ll thread below big rock outcrops and a dramatic overhang, with lush, moist vegetation hugging cold sandstone walls. It’s more about texture and mood than big vistas—think mossy rock, filtered light, and a tucked-in forest feel.
Important Closure Note
The namesake rock “tunnels” are closed due to safety concerns (one entrance is boarded, another area suffered fire damage). The rest of the trail is open—obey all posted closures and do not enter the tunnels.
Route and Access
The trail anchors between two super-convenient access points: one just off the paved walkway to Grandview’s Main Overlook, the other near the baseball diamond/playground by the Main Overlook parking area. Walk it as a quick loop by starting from either end and returning via the lot or paved path. Plan on 15–30 minutes, depending on photo and poke-around time.
Difficulty and Conditions
Short but not flat: there are steps on both ends and some slick rock when wet. Most hikers with basic fitness will be fine, but it’s not ideal for mobility limitations or unstable footwear. Dogs are welcome on leash.
Best Time to Hike
April through October is the sweet spot, and the shade makes it kinder on hot days. Go after dry weather if you can—the sandstone and steps can be slippery when damp. Early or late in the day helps with quieter conditions.
Make It a Mini-Loop Day
Pair this with the nearby Main and North Overlooks for the views this loop doesn’t provide. If you want more trail time in Grandview, the Castle Rock loop in the same area delivers additional cliffline interest and overlook access.
