Thompsons Peak is a 7.2 mile out and back trail located near Fountain Hills, AZ. The trail is rated as moderate and primarily used for hiking.
Definitely a bit strenuous towards the top and it is about .5 mile from the parking lot to the trailhead so total hike is probably about 8 miles. I didn't go past the RF radiation signs but good views near the top. The Dixon trail at the beginning is also real nice through dry creek beds.
Iconic and difficult hike in Fountain Hills. This was my second time and one I would say should be done once a year and no more as it is an effort to get there and to hike it. Very doable, but is arduous in parts as the service road you travel after leaving the Dixie Mine trail feels like it has a 45 degree incline and you have to make your own switchbacks going up and down. Spectacular views and you are very proud of yourself when you make it to the top. This can also be accessed from the Gateway TH by way of Bell Pass and Prospector, but that's a long day hike
This is a great hike, especially for exercise and the views. I wish there weren't that ugly radio station at the top. Don't get too close; apparently you can get irradiated.
Did the Dixie Mine Trail to the Towers Trail (Thompson Peak Trail) to the summit of Thompson Peak. You start at the Golden Eagle Trailhead in Fountain Hills. The trailhead has bathrooms and water and is very well maintained. The start of the Dixie Mine Trail is also very well marked although you have to walk about a quarter mile through a gated neighborhood to reach it.
The first 3.5 miles are on the Dixie Mine Trail and it is quite beautiful. It's basically a hike through a desert landscape. You then turn off onto the Towers Trail (Thompson Peak Trail). The real fun begins about a mile into this trail where you begin to climb...and climb...and climb. About 2200 feet over about 1.5 miles. The trail is paved over the steepest ascents but unless you are in good physical condition, this isn't for the faint of heart. Reaching the summit feels like a real achievement and you are rewarded with one of the best views in the entire Valley of the Sun (at least that I've seen). Going down, while much faster, is also challenging. You really need good hiking shoes with grippy soles to ensure a safe and entertaining descent.
Our entire hike took about 4.5 hours but, as usual, the first three were going up.
The hike to the base of the mountain is boring and long, but once you hit the mountain it goes straight up the radical changes are fortunately paved with cement to avoid slipping. The trail leads up to a radio tower where you can the see whole valley. It does take a long time 3-5 hours I would say on average. I wouldn't recommend running I ran the trail but I couldn't make it half way up the mountain itself.
