Explore Our Natural Landscapes
See native plants in the wild at our six sanctuaries throughout New England
Native Plant Trust sanctuaries in Maine, New Hampshire, and Vermont are open for your enjoyment. All three states have lifted the mask mandate for outdoor spaces, if you are able to stay six feet away from people not in your household. Please avoid crowding at popular sites and also observe the rules to protect the plants. Because visitors must share a narrow boardwalk at Eshqua Bog, in Vermont, please see special instructions in the box at the bottom of this page.
Discover peaceful places and fascinating plants protected for their rarity, variety, or impressive seasonal displays. The sanctuaries are self-guided, with no attendants or fees. Use these tips to get the most out of your visit:
- To learn more about the plants you see during your visit, fire up Go Botany on your phone or tablet.
- Because most of the sanctuaries have no numbered street address, GPS navigation is unreliable; please use the directions provided in the descriptions below.
- Visiting our sanctuaries involves certain risks present in natural areas, including hills, ponds or streams, uneven terrain, insects, and slippery areas. No staff members are present to assist in an emergency. You visit at your own risk, so please use caution.
The following are prohibited at all Native Plant Trust sanctuaries:
- Camping, fires, and smoking
- Mountain bikes, and off-road and other motorized vehicles (except for wheelchairs)
- Horseback riding
- Removing, cutting, or picking plants
- Camping, fires, and smoking
For the safety of all visitors and the protection of plant collections and other natural resources, we do not allow bicycles, off-road vehicles, and vehicles or other power-driven devices used for mobility assistance (with the exception of wheelchairs and scooters) on the paths at Garden in the Woods or in our sanctuaries. The natural terrain and rustic paths at the sanctuaries are generally not accessible. The exception is Eshqua Bog in Vermont, which has an accessible boardwalk.

- Pass others only at the three dedicated passing areas.
- If you are physically able, please return to your vehicle on the loop trail rather than via the boardwalk.

Follow this road for another 1.2 miles. The bog is on the right and is marked by a sign. Park in the turn-off just before the bog entrance.
