The St. Mary's Lake Loop is approximately 11.8 kilometers (7.3 miles) long. Most hikers can expect to complete the full loop in about 3 hours, depending on their pace and how often they stop to enjoy the scenery.
The trail is primarily a single-track dirt path winding through a wooded environment. You'll encounter a mix of roots, some sandy sections, and it can become quite muddy after rain. While there are undulations with short uphills and downhills, the overall elevation change is minimal. The path closely follows the shoreline of St. Mary's Lake, extending into various coves and creek valleys.
Yes, the trail is dog-friendly! You are welcome to bring your furry companions, but please ensure they are kept on a leash at all times to protect wildlife and for the safety of other trail users.
The trail is beautiful year-round, but it's particularly appealing in the autumn when the leaves change color, offering stunning views. Spring also brings lush greenery. Be aware that after rain, sections can become very muddy, so consider conditions when planning your visit.
Yes, there is a $5 per vehicle access fee to enter St. Mary's River State Park, where the trail is located. This operates on a self-pay honor system. No specific hiking permits are required beyond the park entrance fee.
Parking is available within St. Mary's River State Park. The main trailhead is typically accessed from the park's entrance. Given that signage can be inconsistent, it's a good idea to bring a map or use a navigation app like komoot to ensure you find the correct starting point.
The wooded and marshy areas around St. Mary's Lake are home to various animals. You might spot birds like herons, as well as beavers, squirrels, and deer. Keep an eye out, especially in quieter sections of the trail.
While generally rated easy to moderate, the trail isn't a 'walk in the park' due to its length (7.3 miles), rooty sections, and undulations. However, a 7-year-old has reportedly completed it without issues. Consider your children's endurance and comfort with varied terrain. It's a great option for active families.
Yes, the St. Mary's Lake Loop utilizes and intersects with several other trails within the park. You'll find yourself on sections of the White Trail, Green Trail, Cross Trail, and the Pine Trail, among others. The Pine Trail, in particular, offers extra challenges and interesting terrain if you're looking to extend your hike.
This is a multi-use trail popular with hikers, mountain bikers, and horseback riders. Hikers should be aware of cyclists, especially on blind corners or descents. Always be courteous and share the path responsibly. Mountain bikers sometimes find the counter-clockwise route easier or faster.
One insider tip is to be prepared for inconsistent signage; bringing a map or using a reliable navigation app is highly recommended. Also, while the trail can be hiked in either direction, some mountain bikers prefer the counter-clockwise route. Be aware that the trail can get very muddy after rain, so appropriate footwear is essential.
