Check trail conditions before you goβthis area can be muddy or snow-covered well into spring. The climb up is steep and challenging, but the views of the Inner Basin are worth it. Be ready for narrow switchbacks, loose rock, and hikers on the trail. A solid set of tires and good brakes make all the difference on the descent.

Bismarck Lake is a good water source close to the Arizona Trail. The view from here towards Humphreys Peak is spectacular! A great place to take a break or spend the night. There was even a little bit of (silty) water left in late September.

With water being a sparse resource in Arizona ecosystems, this water source is home to many different species of animals and plants. Enjoy this area on the trail to cool off, as there is often an abundance of shade and cool winds in the area.

Reliable water source of good quality, rather a pond, with at least one very nice campsite. But rather unprotected in strong winds.
