Forest Loop Trail Boardwalk (Glacier Bay National Park, Alaska, USA)

Forest Loop Trail is a 1-mile loop in Bartlett Cove, the developed visitor area of Glacier Bay National Park and Preserve. The route combines spruce-hemlock rainforest, small ponds, shoreline habitat and a substantial wooden boardwalk section rather than staying on boardwalk for the entire mile. The National Park Service lists a normal self-guided walking time of about 30 minutes to 1.5 hours. Visitors can start near Glacier Bay Lodge or near the boat ramp, making this one of the easiest short walks to fit into time at Bartlett Cove.

The boardwalk has an added role beyond keeping feet above wet ground. NPS accessibility information identifies a one-half-mile section of the Forest Trail, including the wooden boardwalk leading to a pond viewing deck, as accessible and easy to negotiate. The remainder of the loop changes to gravel, dirt and natural trail surfaces, so the accessibility of the boardwalk portion should not be interpreted as meaning the entire loop meets the same standard.

Where the Boardwalk Fits into the Forest Loop Trail

The name can cause some confusion because Forest Loop Trail is not a continuous one-mile boardwalk. NPS describes the route surface as a mixture of dirt, gravel and boardwalk. The wooden construction is concentrated where an elevated, stable surface is particularly useful in the damp forest and pond environment.

The route moves through two very different Bartlett Cove settings. Part of the walk passes through pond-studded Sitka spruce and western hemlock forest, while another portion reaches the coastal edge and beach environment. This makes the short loop more varied than its distance suggests without requiring a backcountry hike.

Route distinction: visitors specifically seeking the smoothest walking surface should focus on the accessible boardwalk portion rather than assuming conditions remain the same around the entire loop.

Accessible Boardwalk and Pond Viewing Area

The accessible portion is one of the most useful details to understand before arriving. NPS states that Bartlett Cove pathways are generally unpaved and may contain exposed roots and rocks, but identifies an exception on the Forest Trail: a wooden boardwalk leading to a viewing deck overlooking a pond. The agency describes this one-half-mile section as accessible and easy to negotiate.

This does not make the full loop uniformly accessible. Once the route leaves the improved boardwalk area, visitors can encounter natural trail conditions that vary with rainfall and maintenance. Someone using a wheelchair or another mobility device may therefore choose an out-and-back visit on the accessible section instead of completing every part of the loop.

Accessibility planning: surface conditions and individual mobility needs differ. NPS invites visitors who need current accessibility information to contact park staff before their visit, especially when deciding how much of the Forest Trail to attempt.

Ponds, Rainforest and the Boardwalk Environment

The boardwalk passes through a young coastal forest shaped by Glacier Bay’s glacial history. NPS interpretation along the trail explains that some ponds occupy depressions left in glacial moraine. Over time, debris and sediment can create poorly drained conditions that allow water to collect.

One interpreted pond beside the boardwalk has fallen trees, sphagnum moss and buckbean along its margins. NPS notes that such a pond may gradually develop toward muskeg, the acidic, waterlogged bog habitat common in parts of Southeast Alaska. The elevated wooden route lets visitors pass through this wet environment without widening informal paths through saturated soil and vegetation.

The surrounding forest is dominated by the spruce-hemlock character typical of Bartlett Cove. The route is therefore useful for visitors interested in forest succession as well as boardwalk design: the structure crosses terrain where ordinary compacted trail construction would be more vulnerable to moisture and repeated foot traffic.

Walking the Full One-Mile Loop

NPS gives two practical starting options. One is in front of Glacier Bay Lodge, just off the parking lot. The other is south of the boat ramp between the docks. Because the route is a loop, either point can be used according to where a visitor is already spending time in Bartlett Cove.

A normal self-guided visit can take as little as about 30 minutes, but the upper NPS estimate of 1.5 hours is more realistic for visitors who stop at the pond, use the viewing platforms, look along the shoreline or follow interpretive material. Two benches and viewing platforms are listed along the route.

The forest portion accounts for roughly the first half-mile in the NPS description before the trail descends toward the beach environment. The shift from enclosed rainforest to the open Bartlett Cove shore is one of the defining features of the walk.

2026 Ranger-Guided Forest Loop Walk

For the 2026 summer season, the National Park Service schedules a guided Forest Loop Trail walk every day at 1:30 PM from May 22 through September 7, 2026. The program is free, lasts about 90 minutes and covers the one-mile easy route. The meeting point is the Glacier Bay Lodge entryway near the front steps and parking lot.

The ranger program focuses on the landscape left by glaciation and the natural stories visible in the forest and along the shore. Visitors who do not join the scheduled walk can use the self-guided Forest Loop Trail material in the official NPS App.

Program timing can change: anyone planning a day around the 1:30 PM walk should check the current NPS event listing shortly before arrival rather than relying on a past-season schedule.

Rain, Mud and Slippery Boardwalk Conditions

Forest Loop Trail is easy by distance and grade, but Southeast Alaska weather changes how the surface feels underfoot. NPS warns that wet wooden walkways, roots, rocks and muddy trail sections can become slippery. Footwear with dependable traction is more useful here than lightweight footwear chosen only for a short distance.

Bartlett Cove has a cool maritime climate. Summer daytime temperatures commonly reach roughly 50–60°F (10–15°C), and the area receives about 70 inches of precipitation in a year. Rain gear is therefore useful even for a one-mile walk, particularly when the trail is being combined with other outdoor time around the cove.

Wet-boardwalk caution: slow down on damp timber, transitions between boardwalk and soil, steps, roots and shaded sections where moisture can remain on the surface.

Wildlife Awareness on the Forest Trail

Bartlett Cove is developed compared with the park’s wilderness, but it remains bear habitat. Glacier Bay supports both black bears and brown bears, and black bears occur in the forested lower-bay environment that includes Bartlett Cove. A sighting is never guaranteed, but visitors should walk with the same awareness they would use elsewhere in Alaska bear country.

NPS recommends staying alert, making your presence known where vegetation limits visibility, keeping food and personal items controlled, and giving bears room to move away. If wildlife is present on or beside a narrow trail or boardwalk, do not approach for a closer photograph or block the animal’s path.

Pet Rules on the Forest Loop Trail

Pets are not allowed on Forest Loop Trail. Glacier Bay’s current pet rules prohibit pets on park trails, boardwalks and most beaches. Limited pet access is allowed in specified parts of the Bartlett Cove developed area, such as the public-use dock and areas near roads and parking lots, but those allowances do not extend onto the Forest Trail.

Service animals that meet the applicable definition are treated separately under NPS rules. Visitors traveling with a service animal and concerned about wildlife encounters or route conditions can check with park staff before entering the trail.

Getting to Forest Loop Trail at Bartlett Cove

The trail is in Bartlett Cove, about 10 miles by road from Gustavus. Glacier Bay is not connected to the continental road network; visitors generally reach Gustavus by aircraft or ferry and then continue to Bartlett Cove by local road transportation. NPS describes this Gustavus-to-Bartlett Cove road as the only road connection into the park’s developed frontcountry.

Glacier Bay Lodge guests can use lodge transportation between Bartlett Cove and the Gustavus airport or ferry terminal according to current operating arrangements. Taxi and other local transportation services may also operate between Gustavus and Bartlett Cove, so schedules should be checked before arrival rather than assumed.

Visitor Services Near the Trail

Forest Loop Trail begins within the small cluster of visitor facilities at Bartlett Cove. The Glacier Bay National Park Visitor Center is on the second floor of Glacier Bay Lodge, while the separate Visitor Information Station is near the head of the public-use dock.

For the current summer schedule, NPS lists the Visitor Center information desk as staffed daily from 11:00 AM to 5:30 PM during its Memorial Day-to-Labor Day season. The Visitor Information Station is listed as open daily from 7:00 AM to 5:00 PM during its May-through-September operating season. Winter services are much more limited.

The Visitor Information Station area provides restrooms, potable water, park information and maps. The accessibility information for Bartlett Cove also notes modern accessible restrooms in this visitor-services area.

Fees and Reservations for a Trail Visit

There is no entrance fee for Glacier Bay National Park and Preserve, and a private visitor does not need a permit or trail reservation simply to walk the Forest Loop Trail. Separate permits apply to activities such as certain camping and private boating trips, but they are not part of an ordinary Forest Loop visit.

The 2026 ranger-guided Forest Loop walk is also listed by NPS as free. Visitors relying on that program should still verify the day’s schedule because ranger activities can be affected by staffing or operating conditions.

When the Forest Loop Boardwalk Works Best

The Forest Loop is particularly practical for visitors who have one to two hours in Bartlett Cove and want a ground-level look at Glacier Bay rather than only a view from the dock or water. Its location beside the lodge and docks means it does not require a separate backcountry transfer, and its short distance allows time for the pond boardwalk, forest and beach sections without committing to one of Bartlett Cove’s longer trails.

Visitors primarily interested in the wooden structure or an easier mobility option can use the accessible boardwalk section as a shorter out-and-back outing. Visitors comfortable with dirt and gravel surfaces can continue around the full loop for the change from rainforest to shoreline.

Best fit: short Bartlett Cove walks, rainforest observation, pond viewing, visitors wanting an accessible boardwalk segment, families comfortable with natural trail surfaces, and travelers waiting for another Bartlett Cove activity.

Plan more carefully if: mobility requires a consistently improved surface, heavy rain has made natural trail sections slick, winter services are needed, or a fixed departure from Bartlett Cove leaves little extra time.
