The Adirondack Mountain Club has released a 24-page supplement to its guidebook “Adirondack Trails: Eastern Region.”

Written by David Thomas-Train, the supplement describes 12 hiking opportunities at 10 locations in the eastern Adirondacks. Most of the trails are located along Lake Champlain, but the additions include the Cat and Thomas Mountains Preserve near Bolton Landing, on the west side of Lake George. The supplement includes trail trips through marsh, woodland, meadow and island habitats.

The supplement is available for free online at www.adk.org, or for $1 at ADK’s Lake George and Heart Lake properties.

It may also be ordered by sending $1 to Eastern Region Supplement, 814 Goggins Road, Lake George, NY 12845. The supplement material will be included in the next printing of the Eastern Region guide.

ADK publishes more than 30 titles, including outdoor recreation guidebooks and maps and armchair traveler books. Profits from the sale of ADK publications help underwrite the cost of its trails, education, conservation and natural history programs.
