(a) If you own land completely surrounded by wilderness, BLM will only approve that combination of routes and modes of travel to your land that—

(1) BLM finds existed on the date Congress designated the area surrounding the inholding as wilderness, and

(2) BLM determines will serve the reasonable purposes for which the non-Federal lands are held or used and cause the least impact on wilderness character.

(b) If you own land completely surrounded by wilderness, and no routes or modes of travel to your land existed on the date Congress designated the area surrounding the inholding as wilderness, BLM will only approve that combination of routes and non-motorized modes of travel to non-Federal inholdings that BLM determines will serve the reasonable purposes for which the non-Federal lands are held or used and cause the least impact on wilderness character.

(c) If BLM approves your access route under paragraph (a) or (b) of this section, we will authorize it under part 2920 of this chapter.

(d) BLM will not allow construction of new access routes to State and private inholdings in wilderness.

(e) BLM will not allow improvement of access routes to a condition more highly developed than that which existed on the date Congress designated the area as wilderness, except such improvements BLM determines are necessary to protect wilderness resources from degradation.

(f) If you own land completely surrounded by wilderness and you have a valid existing right of access which is greater than the access described in paragraph (a) or (b) of this section, BLM may manage such access to protect wilderness resources while ensuring your reasonable use and enjoyment of the inholding.
