No site in New York's access file falls on Hollow Tree Brook, so the way in is public ground and road crossings rather than a marked landing. 4 blocks of public land front Hollow Tree Brook, and 4.2 of its 3.2 mapped miles run through them.

Ownership from PAD-US as the state publishes it. Where a block has its own page, the name
links to it. The river miles are how far this river's drawn axis runs inside each block, measured here;
the acreage is the whole unit's, most of which is nowhere near this water. "Restricted access" and "access unrecorded" are PAD-US's own words for the block, and
neither one means open — check before you park.
