The remoteness of the park, combined with the varied topography, offers exceptional outdoor holiday opportunities.

Recent additions to the park encompass the eastern side of Atlin Mountain, the Atlin River, a portion of the south shoreline of Graham Inlet and a portion of area in the upper Willison Creek area. Atlin Mountain is a landmark viewscape from the town of Atlin. The additions have high cultural, recreational and wilderness values for the Taku River Tlingit First Nation and the local community.

The climate patterns of the area are continental, with cold, long winters and warm summers. Stormy weather can linger in the valley for long periods. Temperatures decrease with increasing elevation. Because of the latitude, Atlin/Áa Tlein Téix'i Provincial Park has very short days in the winter, but by the June solstice, there is no actual darkness at night.
