Stop Five of the Acadia Earthcache Course focuses on Champlain Mountain's glacial polish—a geological feature most hikers overlook while chasing summit views. You'll learn to read the mountain's history through the granite underfoot.
This stop is part of a larger, self-guided earthcache course that uses GPS coordinates to teach the park's glacial history. Stop five sits along the base of Champlain Mountain, a 1,058-foot peak on the east side of Mount Desert Island. The coordinates for this specific lesson are N 44° 21.560' W 68° 11.522'. You're not here to find a physical container; you're here to observe and answer questions about the smoothed granite left behind by the Laurentide Ice Sheet. It's a detail most hikers rush past on their way to the summit, but it tells the fundamental story of how this entire landscape was carved.
Quick Information
* Entrance Fee: A park entrance pass is required for all areas of Acadia National Park. As of 2026, a 7-day vehicle pass costs $35. A private vehicle annual pass for Acadia is $70. The America the Beautiful Annual Pass ($80) is also accepted.
* Hours: The park is open 24/7, year-round. However, Park Loop Road and many secondary roads close from December 1 through April 14. Access to this location is typically via the one-way section of Park Loop Road, which is closed in winter.
* Best Time to Visit: Late May through October. This ensures Park Loop Road is open for vehicle access to the trailheads near Champlain Mountain. Early morning on a weekday offers the best chance for parking and quiet observation.
* Location: Mount Desert Island, Maine. The nearest town is Bar Harbor. The specific earthcache site is accessed via trails off Park Loop Road.
* Accessibility: The trail to the earthcache coordinates involves uneven, rocky terrain and is not wheelchair accessible. The nearby Park Loop Road has several paved pull-offs with ocean views that are accessible.
* Cell Service: Coverage is generally reliable near the Park Loop Road corridor, but it can become spotty in deeper valleys or on the opposite side of ridges.
* Restrooms: The closest restrooms are typically at the Sand Beach parking area or the Fabbri Picnic Area, both located on Park Loop Road. These are seasonal facilities.
* Parking: Parking for the Beehive and Bowl Trailhead, which provides access to Champlain Mountain, is extremely limited. The small lot often fills by 7:30 AM on summer mornings. Overflow parking is along Park Loop Road where permitted, but this adds significant walking distance.
Getting There
The primary access point for the Acadia Earthcache Course Stop Five: Champlain Mountain is via the Park Loop Road. From Bar Harbor, follow signs for the Hulls Cove Visitor Center to begin the 27-mile loop. The one-way section begins just past the visitor center. After passing Sand Beach, look for the small parking area for the Beehive/Bowl Trailhead on your left. This is the most direct trailhead for reaching the Champlain Mountain base.
If that lot is full - which it usually is - continue driving the one-way loop. You can also access the mountain from the Gorham Mountain parking area or from the Sieur de Monts area via the Emery or Kurt Diederich's Climb paths. The trek from Sieur de Monts to Sand Beach, which summits Champlain Mountain, is a 4.1-mile option that connects multiple trails. Rangers at the visitor center can provide a current trail map showing all connecting routes.
What to Expect
Glacial polish gives the granite a texture like fine-grit sandpaper—smooth to the touch with faint parallel striations. Look for exposed bedrock near the mountain's base where the ice sheet planed the surface flat. Unlike weathered granite, this polished rock feels almost waxy, with no sharp crystalline edges.line bite of freshly broken rock.
The area around Champlain Mountain is a nexus for some of Acadia's most famous and strenuous trails. The Precipice Trail (closed for much of the spring and summer for peregrine falcon nesting) ascends the cliffs directly. The Beehive Trail, with its iron rungs and ladders, is just next door. As a result, the energy at the trailhead is one of focused preparation. You'll see people tightening boot laces, checking water bottles, and looking up at the cliffs with a mix of excitement and apprehension. The earthcache site offers a quieter, more grounded counterpoint to that aerial drama.
The forest here is a mix of spruce and pine, and the air often carries the salt tang from the ocean just a few hundred feet below at Sand Beach. On a busy day, the soundscape is a mix of wind, distant waves, and the occasional echo of hikers calling to each other on the cliffs above.
Top Attractions & Points of Interest
The Glacial Polish Site
This is the destination. The smoothed granite is the textbook example of the abrasive power of a glacier, which dragged billions of tons of rock and sediment across this bedrock. Take your time here. Run your hand over the rock (when dry) to feel the difference. The earthcache questions will direct your observation to the direction of the glacial flow and the evidence left behind. It's a 3.5-billion-year-old story written in stone.
Champlain Mountain Summit
The reward for the climb. At 1,058 feet, the summit offers a 360-degree view that includes Frenchman Bay, the Porcupine Islands, Dorr and Cadillac Mountains to the west, and the open Atlantic to the south. On a clear day, you can see the Schoodic Peninsula across the water. The summit is mostly bare granite, so finding a spot to sit and take it in is easy. Most visitors underestimate how quickly the weather can change up here - a bank of fog can roll in and obliterate the view in minutes.
The Beehive
While a separate peak, the Beehive is intrinsically linked to this area. This 520-foot dome of granite is famous for its non-technical but exposed climb using iron rungs and ladders. The parking lot serves both areas. Even if you don't climb it, the view of the Beehive from the base near the earthcache site is impressive. You can watch ant-like figures slowly progressing up its sheer face.
Sand Beach
A short walk or drive down the hill from the trailhead. This is the only sizable sandy beach in the park, in a small cove between granite headlands. The water is cold - rarely above 55°F (13°C) even in summer - but the setting is spectacular. It's a great place to cool your feet after a hike or to simply watch the surf. The contrast between the mountain terrain just above and this pocket of sand is striking.
Gorham Mountain
Accessible from the same parking corridor, Gorham Mountain offers a slightly less strenuous alternative with outstanding coastal views. The Gorham Mountain Loop is a 3.5-mile hike that connects with the Cadillac Cliffs and offers panoramic views of Mount Desert Island. The Acadia Earthcache Course Stop Four is located along this trail, allowing you to connect multiple geologic lessons in one hike.
Activities
Hiking
This is the core activity here. The network is dense and interconnected.
* To the Earthcache & Summit: The most direct route is via the Bowl Trail, which connects to the Champlain North Ridge Trail. It's a steady, rocky climb. The full loop using the Bear Brook Trail and returning via the North Ridge is roughly 3.5 miles with about 1,100 feet of elevation gain.
* The Sieur de Monts to Sand Beach Trek: This 4.1-mile point-to-point hike, facilitated by the Island Explorer bus, is a fantastic way to experience the area. It summits Champlain Mountain and ends at the ocean. You'll pass the earthcache site and get the full topographic story.
* Connecting Trails: Experienced hikers often link Champlain with neighboring Dorr Mountain via the Dorr Mountain South Ridge Loop for a longer, more strenuous day.
Geocaching & Earthcaching
The primary reason for a targeted visit to stop five. Have your GPS device or smartphone app ready with the posted coordinates and the required questions from the official earthcache listing. This is an educational scavenger hunt that requires you to read the landscape and submit your answers to earn a digital smilie.
Photography
The summit is an obvious spot, but the glacial polish itself can make for compelling macro shots, especially in the angled light of early morning or late afternoon. The striations catch the light beautifully. Wider shots from the Champlain North Ridge Trail looking back toward the Beehive and Sand Beach are classic Acadia images.
Wildlife Viewing
This area is prime peregrine falcon territory. Even if the Precipice Trail is closed (which it is for much of the nesting season from March 1), you may see these raptors soaring on the updrafts along the cliffs. Keep an eye out for ravens, which also nest in the crags and perform acrobatic flights. For a broader look at the park's fauna, our guide to wildlife viewing details the best spots and seasons.
Seasonal Guide
* Spring (April - May): Park Loop Road usually reopens in mid-April. This is a quiet time to visit the earthcache site, but trails can be muddy and slippery. Be aware that the Precipice and other cliff trails are closed for falcon nesting. Black flies emerge in May.
* Summer (June - August): Peak season. Parking at the Beehive lot is a pre-dawn endeavor. The weather is generally pleasant, but fog can persist for days. This is the most reliable time for all trails to be open (excluding falcon closures).
* Fall (September - October): Arguably the best time. Crowds diminish after Labor Day, the weather is crisp, and fall foliage peaks in early to mid-October. Park Loop Road remains open until December 1.
* Winter (November - March): Park Loop Road is closed. Access to Champlain Mountain is possible by foot or ski from other open roads, but it becomes a significant wilderness trek. Only experienced winter hikers should attempt it. The earthcache site will be under snow and ice.

Practical Information
A park entrance pass is mandatory. You can purchase one at the Hulls Cove Visitor Center, at automated fee machines at Sand Beach or other locations, or online in advance. The Island Explorer bus system operates from late June through early October and is free with your park entrance pass - it's the best strategy for tackling point-to-point hikes and avoiding parking headaches.
For camping options, the park's two main campgrounds on Mount Desert Island are Blackwoods (near Bar Harbor) and Seawall (near Southwest Harbor). Both require reservations via Recreation.gov. Duck Harbor Campground is on Isle au Haut and is for hike-in use only. For other lodging and accommodations, Bar Harbor is the main hub.
Safety & Preparation
* Footwear: This is non-negotiable. Wear sturdy, ankle-supporting hiking boots with good traction. The trails are relentlessly rocky and root-strewn.
* Water: There is no potable water at the trailhead or on the mountain. Carry at least 2 liters per person for a summit hike.
* Weather: Mountain weather changes fast. Carry layers, including a windbreaker or rain shell, even on a sunny morning. Hypothermia is a risk in cool, wet, windy conditions even in summer.
* Cliff Safety: Stay on designated trails. The cliffs on Champlain and the Beehive are sheer and deadly. Do not approach edges, especially in wet or windy conditions.
* Falcon Closures: Respect all trail closures for peregrine falcon nesting. Rangers strictly enforce these to protect the birds. Check at a visitor center or online for the current status.
* Emergency: Cell service is not guaranteed. Know your route and turn back if weather deteriorates. In an emergency, call 911.
Insider Tips
- Park Once, Ride the Bus: Drive to the Hulls Cove Visitor Center, park, and take the Island Explorer's Sand Beach route to the Beehive stop. After your hike, take any bus back. It eliminates the parking battle entirely.
- The Early Shift: If you must drive, aim to be at the Beehive parking lot by 6:45 AM. You'll get a spot and have the glacial polish site to yourself in the quiet morning light.
- Link the Lessons: The earthcache stops are designed as a course. Consider doing stops four (Gorham Mountain) and five (Champlain) in one longer hike using the connecting trails.
- Skip the Summit on Foggy Days: If the summit is in the clouds, the glacial polish site is still fascinating and worthwhile. The fog can even enhance the texture and color of the rock.
- Post-Hike Reward: After your hike, drive two minutes down Park Loop Road to Thunder Hole. Time your visit for mid-tide and rising for the best chance to hear the cavernous "thunder." It's a touristy stop, but for good reason.
- Check for Carriage Road Closures: As of spring 2026, carriage roads are closed for mud season. If you plan to incorporate them into a hike, verify they have reopened.
- The Quiet Alternative: For a longer but less crowded approach to Champlain Mountain, start at the Sieur de Monts Spring area and take the Emery Path or Kurt Diederich's Climb. You'll pass the Nature Center and Wild Gardens of Acadia first.
Links may earn us a commission at no extra cost to you. We only recommend gear we believe in. For this hike, focus on footwear with aggressive tread like the Salomon X Ultra 4 Mid GTX and a reliable hydration reservoir like the Osprey Hydraulics LT 2.5L. A small pair of binoculars will greatly enhance your ability to spot falcons and see the striations in the rock from a distance.
The Acadia Earthcache Course Stop Five: Champlain Mountain turns a hike into a detective story. You're not just climbing a mountain; you're reading the evidence of the force that built the stage for the climb. It's a reminder that in Acadia, the drama isn't only in the views from the top, but in the ancient history written on the stone beneath your feet.
