Mesa Falls
Ashton, Idaho
10.0 miles NE of Ashton, IdahoUpper Mesa Falls, aka Big Falls, is an absolutely awesome waterfall on the Henrys Fork of the Snake River. The falls drop 114 ft. and measure 300 ft. across. To get to the falls from the parking lot is 0.2 miles of paved walkway and several sturdy stairs with plenty of gaurdrails and handrails. There are several platforms along the route for viewing and taking photos. Catch it in the morning to see the rainbows in the lingering mist that often rises well above the platforms. There's a wheelchair accessible path that can get a pretty good view of the falls but does not go right down to it.
Lower Mesa Falls is about a mile down river from the Upper Falls. There's two great viewing options. One is from a cliff hovering 200 feet above the falls and the other is from the the Observation Site sitting 0.25 miles away and almost 500 feet above the falls. To get to the cliff above the falls, there's a trailhead on the South East end of the main parking lot. The trail is 1 mile each way (2 mile out and back) with about a 100 ft. difference in elevation (about the same as the stairs the the Upper Falls platforms). The trail goes through the woods well away from the river itself but there are no guardrails at the end when you're peering over the edge of the cliffs to see the waterfall. To see the falls from the observation site is free and the walk from your car to the lookout is only about 500 ft.
This is an Idaho State Park and there are day use fees. Passes have reciprocity with Harriman State Park which is only about 20 minutes away. Get there before 5pm to check out the old inn which has been transformed into a fun and informative visitor's center.
Monkey Rock
Saint Anthony, Idaho
4.1 miles SE of Saint Anthony, IdahoMonkey Rock features a beautiful waterfall you can wade right up to during the summer. Just under the waterfall is a great spot to wade around in or even some shallow swimming pretty good for small children. Maybe you just want to take advantage of the great bank to bask in the summer sun. The water temperature is fairly cool, which by no means is unwelcomed during the hot summer months. You'll get used to the water fairly quickly once you're in. The waterfall is a fun feature at Monkey Rock, not to mention a popular engagement photo backdrop. The name "Monkey Rock" is derived from the "monkeys" who jump off the rocks at the top of the falls to the pool below. Though not a great height, it's important to be careful and only jump into areas clear of rocks and other hazards and where the water is deep enough that you won't hit bottom when you jump. There really isn't a safe spot to jump from the falls as it doesn't usually get more than 5 feet deep.
The real jumping location is off the Hog Hollow Bridge up the road from the waterfall.
PLEASE NOTE: On the roads leading to Monkey Rock, the speed limit is 35 mph for the last mile. There are kids, cows, horses, and dogs along that road and many people tend to speed going to and from Monkey Rock. Please slow down and stay safe.
Darby Wind Cave
Driggs, Idaho
7.6 miles E of Driggs, IdahoDarby Wind Cave is a beautiful hike full of waterfalls, wildflowers, streams, and mountainous views. The sites you see will depend on the time of year you visit but it will always be beautiful and just a little bit of a challenge.
The trail starts out relatively flat, following along close to where the old road used to run. There are a few creek crossings which will vary in difficulty depending on how much snow there was over the winter and how long it's been since things began to thaw. Late summer will usually find you crossing dry or nearly dry creek beds. If you hike when runoff is high, there are log bridges. You don't have to be highwire ready but one of the bridges will take a little bit of balance. The trail turns up South up into the canyon. About as soon as it starts to go up, you'll turn and begin a series of switchbacks (10 turns). These will take you up the East wall of the canyon.
The switchbacks are not incredibly steep but you'll gain elevation pretty quickly. After the switchback, the trail follows along a rim above the canyon where you can look across the canyon and see two beautiful waterfalls and mouth of the cave seemingly high overhead. At the South end of the canyon, you'll come across a rock overhang. It's fun at any time during the summer but earlier when the water is higher, you'll find a little waterfall and stream that the kids will love to play in and you'll be hard pressed not to soak your head and feet and cool off a bit yourself.
From the the overhang, the hike continues West along the South end of the canyon through some more forest and a beautiful meadow. Take a minute to look up from the trail to enjoy the view of Fossil Peak to the South. Just after the meadow, you'll begin another series of switchbacks up to the falls and cave. The first set (2 turns) will take you up to a dispersed campsite and monument. The next leg will take you to the creek where you can look up and get photos of the falls and cave. The next set puts you out just underneath a very large and beautiful waterfall that drops out over a ledge. The ledge itself is a popular repel accessible from above. You can walk all the way around these falls and even catch some spray on the downwind side. The next set of switchbacks are stairs cut out of the rock. Halfway will take you to an even better view of Fossil Peak and the remainder will take you to the mouth of the cave itself. To enter the cave, you'll have to cross one more creek which can be pretty scary and dangerous when the water is high. Entering the cave during high water can be just as scary.
Once you're in, the Wind Cave snakes through the Darby Formation, a thick layer of 350 million year-old dolomite. A flashlight for the cave is a definite must. Near the mouth, there's a series of ledges popular for bouldering. Just up about 100 yards, you'll come to a small hole you'll have to crouch to get through. You'll quickly realize why they're called the wind caves as you're blasted with wind from the caves coming out that hole. After about 200 yards, you'll want your climbing gear. The caves stretch for miles and if you go far enough, you'll enter the part known as the ice caves. Travel far enough, you'll come out the other side. Be careful though. The cave becomes pretty cavelike and it's really easy to get lost and, even in the busy season, it may be days until that nightmare ends with a rescue team.
The hike is about 3.1 miles from the South Fork Darby Canyon trailhead to the caves and is a 1,800 feet elevation gain. You'll find a lot of resources that claim the hike is a shorter distance. These sources either begin from the end of the old road or don't take into account one or both series of switchbacks. The cave itself sits at 8,940 feet above sea level.
Cress Creek Nature Trail
Rexburg, Idaho
11.9 miles S of Rexburg, IdahoMeandering along the scenic South Fork of the Snake River, the beautiful 1¼ mile Cress Creek Nature Trail will lead you on a journey through sagebrush-grass communities, over juniper covered slopes, and along a lush perennial creek. Cress Creek derives its name from the watercress plant, a favorite food of the moose that live in this area. With clear skies, prepare for an expansive view of the Snake River, volcanoes and farmland. The site offers ample parking, restrooms and trail accessibility, which attract a wide spectrum of trail users to the area. You will become familiar with life in the Cress Creek area as it is now and as it was long ago. If you hike quietly you may see deer, rabbits, small lizards, or possibly an eagle or a moose. The nature trail is self-guided with many beautiful interpretive signs posted along the way to assist you. The first half-mile of the trail is accessible by wheelchair.
On the northeastern corner of the trail, there's an overlook trail. Parts of it are pretty nice like the rest of the loop but some is barely recognizable as a trail. Parts of the trail are steep and parts of it go over some pretty loose rock. It goes for about a ½ mile all the way to the top of the hill. Just below the rim, there are several really cool caves. From the top, you can see from Rexburg to Idaho Falls.

Idaho Falls, Idaho
