  • Can't decide what was more beautiful, the quantities of cacti or the big jagged mountains on our 21 mile drive. We took a boatload of pictures. Piece of advice: get an early enough start to stop for a...  more »
  • Came here to see the monument. Visited the visitor’s center, saw a quick Ranger discussion on reptiles and took the cactus walk there. Nice. The setting was perfect, as was the weather. We took the Aj...  more »
  • This review is about the Twin Peaks Campground - absolutely loved it! My husband, dog and I planned to only camp here for 2 nights over New Years. But we discovered that the campground actually gets great Verizon & AT&T reception and we work remotely, so we were able to stay for a week and work here! Spacious sites, not crowded, beautiful cacti throughout, super affordable at $16/night, very quiet, picnic benches, awesome sunsets, dog-friendly in the campground and at the campground perimeter trail. As with all national monuments/parks, more dog-friendly (on-leash) trails are needed throughout though. Nice to check out the free ranger programs at the nearby amphitheater at 7pm daily. Generator time of 8-10am and 4-6pm was enough to keep laptops charged and work full-time. People respect those hours, which is nice. Dump station and fresh water station that we drove over to every few days. This campground was very hard to leave & I'd definitely stay here again and recommend it!
  • Having just visited Saguaro NP, I continued onto Organ Pipe NM. In February, the weather was amazingly warm. The road between the parks wasn’t the best. Much of it was narrow (no shoulders), twisty, and the pavement not in the best of shape. More surprising, though, were border patrol agents. They were everywhere in just about every mode of transportation possible. I have to admit I was concerned about visiting Organ Pipe alone, being on the Mexican border. Having black hawk helicopters flying close overhead was a bit concerning. Between check points and agents seemingly behind every bush (in vehicles, on horse back and also the copters), I eventually shifted to a feeling of maybe being a little safer. But it was mind-blowing. This is a fantastic park encompassing 517 square miles. It is also designated an International Biosphere Reserve. My biggest disappointment was being told that there was no campground (not prepared) only to find one here. One can definitely spend more than an afternoon here. Like Saguaro NP protecting its namesake, Organ Pipe NM protects a large section of the Sonoran Desert where the northern population of organ pipe cactus reside. But there is so much more here, well worth a visit.
  • If you love cacti, this is a place to go to. It is well worth the 1- hour drive from Interstate 10. Once at the park, you can either take a 20 or a 40-mile loop to see the cacti. I drove the 20-mile one, which was a well graded dirt road my low-clearance tiny car took with ease. Bring plenty of water, as it gets pretty hot even in the middle of winter.
  • We will be going back. Well maintained campground with tents and RVs nicely separated. Nice sky is dark for Star gazing and great concentration of organ pipe and saguaro cactus.
  • What a great and worthy stop, especially if you are along your way to mexico. Yeah, there are lots of border patrol people everywhere. The cactus are beautiful and amazingly tall, the landscape is a lot more lush than just desert. Weather is always fantastic here in winter. I could have spent a lot more time here.
