Hamilton's Hideaway

 is a small cave in the side of a cliff face in the Capital Wasteland.

Hamilton's Hideaway is easily found by traveling about a mile NE of Arefu into the river bedthere and following the cliff's rock until you find the entrance. It is mentioned by Sheriff Evan King in Arefu as a possible location of The Family as part of the Blood Ties quest.

Three Dog will also tell you of this location and give you a key to the hidden weapons cache inside after you help him restore GNR's broadcasting capabilities, but only if you have already talked to Doctor Li about your father's whereabouts before completing the quest. The cache is behind a cell door in the northwestern-most area, behind some rubble. You will see a locked brass cell door in the side of the cave, use the key Three Dog gave you to gain entrance.

The cave itself is populated with Radscorpions, Radroaches, and two Raiders.
