    Whoever owns this business does a good job making the experience worth the trip and price. The walkway from the parking lot is surrounded by western decor and a bunch of peacocks roaming around. The fee to enter the cave includes access to a museum loaded with animal taxidermies and unique items. They provided us with lights to travel the cave. The route takes you 1/4 mile into the cave which I believe is a lava tube. Turn off your lights and you're in pitch darkness. Pretty cool experience and definitely worth the drive.

    Totally worth it. Kids were obsessed with the museum, compared it to the Mystery Shack in Gravity Falls. They have a giraffe in there! Cave was deep and cold and fun to just get a lamp and go. Great photo ops, stone heads, peacocks, taxidermy. So fun.

    Cave walk, ceilings are about 50ft!

His parachute prematurely deployed as the Skycycle left the launching rail but winds caused him to drift into the canyon. At the bottom, he landed near the water. If he landed in the water, he probably would have drowned, due to a jumpsuit/harness malfunction the kept him strapped in the vehicle. Surprisingly, he survived the jump with minor injuries. At the city's visitors center, Knievel's supporters erected a monument to their hero with a carved likeness of the rocket motorcycle. It's engraved, "Robert 'Evel' Knievel: Explorer, Motorcyclist, and Daredevil. Attempted a mile-long leap of the Snake River Canyon on September 8, 1974 employing a unique Skycycle. The large dirt ramp is visible appox. 2 miles east of this point on the south ridge of the canyon. Donated to the community by Sunset Memorial." The mound of his jump is from the marker.

We started our visit at the Visitor Center where we saw is a :30 video providing the history of the site & history of Executive Order 9066 which authorized the incarceration. Rangers started our tour at a relief model of the camp during the war when over 30,000 were incarcerated. We visited the in ground storage, sparse cramped restored barracks, latrine, mess hall & restored baseball field. The Visitor Center has many displays & artifacts describing the history of the war, incarceration, and Minidoka. There is also an honor roll listing volunteers that filled the ranks of the infamous Combat Team & Military Intelligence Service. I was surprised how emotional I became looking at the site, the number of Japanese here & the sparse, rough terrain. Volunteer Parc Rangers here are granddaughters of those that survived these camps.

The new visitor center is great and has lots of exhibits inside. Be sure to read their hours and seasonal information carefully before visiting. As in 2024, they're not open until May 24, and then only on the weekends plus Friday. The grounds are open to visit at any time during the day and the park stamp is available outside in a closed and covered box.

    Food: NA/5 Service: NA/5…read moreAmbiance: 5/5 Parking: 4/5 Family friendly: 5/5 Stroller friendly: 3/5 ADA accessible: 3/5 My family and I came here strictly for the sand dunes and observatory, late on a Sunday evening around 845-9pm. (Apparently the observatory is closed on Sunday?). Entrance fee is $7 cash or check when the gate is closed. You have to be in some type of shape as ascending the 60 deg incline hill of sand takes a bit of muscle and cardio endurance to make it up. Once at the top though, it's a serene and calming experience. On the backside of the first sand dune, the Snake River runs through. Similar to an Oasis in the desert. However, as some people may know or experience, wherever there is water, comes the bugs. As the sun dipped below the horizon, the bugs (mosquitoes) attacked. Not just one or two, swarms of mosquitoes. If you're like me and have allergic itching reactions to pest bites, be warned and have full body covering along with repellent. By the time we escaped to the car my son had been bit on the head and face. Just a forewarning. Bruneau Dunes State Park seems like a cool place to be. There were 3-4 individual camping locations that's were RV friendly and vast spaces for kids to run around. Sand Dunes themselves are not WC friendly unless you invent some type of sled to push/pull the WC up the hill. Also, make sure when dusk arrives, COVER UP!

    I'm always on the hunt for an adventure so when I saw this was only 30 mins from my hotel, I knew I…read morehad to make a morning out of it! The entry fee was $7 and the drive to the dunes was quiet and peaceful. I went by myself and felt safe enough exploring the area alone. The views were gorgeous! This is truly a hidden gem tucked away in the farm lands. If you're in the mountain home area, check this place out!

It spans across the Snake River Canyon connecting Twin Falls. Its 1500 ft long and 500 ft above the Snake River. Free parking, grass and benches to relax and people watch. This view is spectacular and don't forget to be patient and watch for the jumpers off the bridge! The Perrine Bridge is one of the only legal bridges in the USA to BASE jump off of. These jumpers are professionals, and pack their chutes near the Visitor Center. I actually got to witness a jumper, it was amazing to see. There is a company that you can hire to jump with you, I passed on that, Lol! Cool stop, don't miss it.

My thrill level maxes out running a blender without a lid on! Last month while traveling through Jerome, Idaho, we stopped in Twin falls to get a closer view of the beautiful Snake River and its surroundings. After parking in the Twin Falls visitor's center parking lot, I took some pics and videos. I managed to time things right and witnessed two daredevils base jump. (Building, antenna, span, earth.) Incredible! Apparently it is one of few places in the nation where it is legal to jump all year round. (Again, nope!) I'd love to return to explore the Shoshone Falls or Zip line at Centennial Waterfront Park but BASE jumping...........A HARD NOPE! Please view my video under the photo\video section of this review site. Thank you.
