The Lookout Trail Highpoint, aka Peak 3949, is a summit located in the very popular Tom’s Thumb hiking area in northeast Scottsdale, AZ.  It is one of the highest peaks in the McDowell Mountain Range. 

Located just over a third of a mile south of Tom’s Thumb, the summit is only about 80 yards off the trail to The Lookout.

Although the summit seems minor, it actually has a prominence of about 335’ between it and East End 4,067’, the highest summit in the McDowell Mountain Range. 

While overshadowed by Tom’s Thumb, there are excellent views from the summit.  This is a worthy destination for hikers, and especially for peak baggers. 

As with most lower elevation Arizona mountains, the best time to hike here is between November and March, in order to avoid the heat and the critters. 

Getting There

Take the 101 Highway to North Pima Road and drive 4 miles north on Pima to Happy Valley Road. Take a right on Happy Valley and continue for about 5 ½ miles to Ranch Gate Road.  This is the 2nd signed turn off for the Tom’s Thumb Trail.  The first is at Alameda, but if you take Ranch Gate Road, it is paved the entire way to the trailhead. 

The trailhead is very large, and very popular, with plenty of spots to park; and excellent trails.


Start from the bathrooms at the south end of the trailhead.  Take the trail as it steeply switchbacks.  After about 1.4 miles,there is a junction with the Tom’s Thumb Trail. Take a right at the junction and continue towards Tom’s Thumb.  The trail is steep in sections, with gorgeous rock formations along the way.

After a third of a mile, there is a junction with The Lookout Trail. This trail heads to the south end of the ridge, where there is a view of the entire McDowell Mountain Range. 

Peak 3949 can be reached before you reach The Lookout.  From the junction with the Tom’s Thumb Trail, follow the trail for 1/3rd of a mile and you’ll be right under the summit.  Walk carefully up the slope and onto the obvious summit.  There is ample room to avoid various types of cactus plants during the late fall and winter.

It is a little over 2 miles to the summit from the trailhead, gaining about 1,250’.  However,there are plenty of add-on miles, including heading all the way to The Lookout, to the base of Tom’s Thumb, or even up to East End.

Red Tape

The park is open sun-up to sun-down only. No overnight parking or camping allowed.
