You can access the trail from the Blue Lake Road Trailhead. Public transport is also an option, with buses capable of carrying bikes, making it easily accessible.
Yes, this trail is generally considered easy to moderate, making it suitable for families and individuals with some hiking experience. The lower sections, rich with thimbleberries, are particularly engaging for younger hikers.
The path is largely a gravel trail, but expect uneven ground with roots, rocks, and potentially muddy sections, especially after rain. While some sections involve uphill climbs, the trail has been recently refinished, making it a bit less steep from the south trailhead. Sturdy hiking boots are recommended for comfort and ankle support.
The trail offers beautiful views of Thimbleberry Lake and the pristine Heart Lake, known for its reflective waters and panoramic vistas. You'll also pass through lush forest ecosystems, see thimbleberry bushes, and enjoy stream views, including Thimbleberry Falls.
Yes, dogs are allowed on the trail. However, it's always a good idea to keep them on a leash to ensure their safety and respect for other hikers and wildlife.
The Thimbleberry-Heart Lake Trail is located within the Tongass National Forest. Generally, there are no specific permits or entrance fees required for day hiking on trails like this within the forest. However, always check the latest regulations on the official Tongass National Forest website for any updates, especially if planning extended stays or specific activities.
The trail is a popular year-round destination. In late summer and early fall, the thimbleberry bushes produce vibrant red berries. In summer, both lakes are popular for swimming, and in winter, they are great for ice skating. Be prepared for potentially muddy conditions after rain, regardless of the season.
The area is known to have bears, especially when berries are ripe. It's important to be bear-aware, carry bear spray, and know how to use it. You'll also observe various local flora and fauna within the forest ecosystems.
The estimated duration for completing the trail is around 48 minutes, covering a distance of approximately 2.6 kilometers (1.6 miles). This can vary based on your pace and how much time you spend enjoying the scenery at the lakes.
For a potentially less steep ascent, consider starting from the south trailhead, as sections have been recently refinished. Remember to wear sturdy hiking boots due to uneven ground and potential mud. Also, be aware that while there are beautiful views, a portion of the trail runs under power lines.
The Thimbleberry-Heart Lake Trail is primarily an out-and-back route. You can hike to Heart Lake and return the same way, or continue to the Blue Lake Road Trailhead.
