We are pleased to announce that The Keeper's House in Dobbs Ferry will reopen to the public on Saturdays and Sundays from 1pm-4pm starting June 12th.

Come visit and check out our permanent interactive exhibition about the history of the tunnel and the trail.

Masks will be required and there will be limits on occupancy for each room.

The following are just some of the highlights of my walk which was completed in three outings and is presented in the sequence of completion. This effort was also a learning experience for me as was my 26-mile walk. Some examples: 1) the use of inverted syphons to compensate for elevation changes was genius; 2) how Gunter’s chain determined the 66’ width of the OCA; 3) and the incredible mansions and the people who occupied them along the 41-mile route.
