Frequently Asked Questions

What is the best way to access the Frank Bolles Preserve loop?

The trail typically starts from a designated parking area. However, recent reports (as of May 2024) indicate that the trail leading directly from the parking area can be inundated with water, requiring some route finding and a bit of a bushwhack to navigate a substantial wetland. Be prepared for varied conditions, especially after heavy rain or during spring thaw.

Is the Frank Bolles Preserve loop suitable for jogging beginners?

This route is rated as difficult for jogging. While some sections are wide and generally easy, the varied terrain, including leafy surfaces, gradual climbs, and potentially wet or snowy conditions, can make it challenging. Joggers should have a good level of fitness and be prepared for uneven ground and possible route finding.

What kind of terrain can I expect on this route?

The terrain features a leafy surface through pine and oak forests, with sections that are wide, particularly the Heron Pond Trail. You'll encounter glacially formed kettleholes and eskers, and the trail generally rises gradually westward towards Bickford Heights. Be aware that conditions can vary significantly, from bare ground to deep snow in spring, and some areas may be wet.

What natural features and wildlife might I see along the way?

The preserve boasts diverse landscapes including forests, wooded swamps, and streams. A prominent feature is Heron Pond, also known as Lonely Lake, an eight-acre kettlehole. You might spot various wildlife, including moose, black bear, white-tailed deer, and numerous bird species. Scenic views of Mount Chocorua and the White Mountain National Forest are also possible.

Are dogs allowed on the trails?

Yes, dogs are generally welcome in the Frank Bolles Preserve. However, they must be kept on a leash at all times to protect wildlife and ensure a pleasant experience for all visitors. Please remember to pack out all pet waste.

What is the best time of year to jog this loop?

Spring and fall offer pleasant temperatures and beautiful scenery. However, spring can bring significant challenges due to melting snow and water inundation, potentially requiring bushwhacking. Winter jogging is possible but requires appropriate gear for snow and ice. Summer can be warm, but the forest provides shade. Always check recent trail conditions before heading out.

Do I need a permit or is there an entrance fee for the preserve?

The Frank Bolles Preserve is co-managed by The Nature Conservancy and Chocorua Lake Conservancy. There are no entrance fees or permits required for day use of the preserve. You can find more information on their website: nature.org.

Does this route connect with other trails?

Yes, the route incorporates sections of other trails within the preserve. Specifically, it passes through parts of the Liberty Trail and the Bolles Trail. The preserve's trail system, including paths like Old Mail Road, Middle Trail, and Lake Trail, can be combined to create various loop configurations and provide access to the western edge of Chocorua Lake.

What should I bring for a jog on this trail?

Given the trail's difficulty and varied conditions, it's advisable to bring sturdy trail running shoes, plenty of water, a map or GPS device (as route finding may be necessary), and layers of clothing suitable for changing weather. Insect repellent is recommended during warmer months. If visiting in spring or winter, be prepared for wet or snowy conditions.

Are there any notable historical or ecological aspects of the preserve?

The Frank Bolles Preserve is a 247-acre natural area, a gift from Evelyn Bolles Phenix, daughter of the 19th-century naturalist and writer Frank Bolles. It's ecologically diverse, encompassing forests, swamps, and streams, and is home to approximately 160 species of flora and fauna. Combined with the adjacent Clark Reserve, it forms a larger 518-acre natural area.
