Come along on an adventure to Thunder Mountain. Dunderberg, historically referred to as Donderberg, is a Dutch word that means “thunder mountain.” The mountain earned its name from the Dutch settlers because of frequent thunderstorms in its vicinity. As we explore the area, we’ll enjoy a quieter, less-traveled part of Harriman State Park. We’ll pass by the tunnels of the long-abandoned Dunderberg Spiral Railway, traverse a pass used by the British military commander in the Revolutionary War, and take in beautiful views of the Hudson Valley.

Fall in love with winter!

If rocks and walls are meant for climbing, then so are frozen waterfalls! Whether you have experienced the unbridled joy of climbing or are a first-timer, join us for a trip to the Catskill Mountains to climb water that has frozen solid running down vertical rocks. Our ice guides will set up multiple ropes, so you will get a chance to try routes of varying difficulty and climb as much as you want throughout the day. We will teach you the technique and give feedback and beta throughout the day. This amazing, unique winter experience is a must-try for every adventurer!

We will provide all the equipment that you need, including harnesses, helmets, mountaineering boots, and crampons. Please email us your shoe size.

Please note, if we are having a warm winter and there it’s too warm or there is no ice, we will do our best to run this as a rock climbing trip (if the conditions allow).

What’s included:

Let’s go snowshoeing! You don’t need any prior experience to join us on this wonderful winter trip. We are going to the Catskill Mountains to play in the winter wonderland and try snowshoeing. We’ll provide the snowshoes and teach you the basics. Don’t worry, if you can hike, you can snowshoe. Beginners welcome! It’s day of fun in the snow you are not going to want to miss!

Note, the exact location of the hike may vary, depending on the best snow conditions. If weather does not cooperate and there is no snow in our region, it will be a regular winter hike!

WINTER CHALLENGE 2025! We are doing all four 3500 peaks that have to be climbed in winter to join the 3500. If you climb all four with us this winter, you will get our Winter Challenge patch! The four peaks are Panther, Slide, Balsam, and Blackhead. The four peaks are Panther, Slide, Balsam, and Blackhead.

“Here the works of man dwindle in the heart of the southern Catskills.” -John Burroughs

Slide, the tallest mountain in the Catskill Mountains, is located in the region’s most popular wilderness area. This hike has a little bit of everything — bubbling brooks, historic trails, and spectacular views. Just below the summit is a plaque commemorating John Burroughs, who was born in the Catskills and devoted his life to writing. While there, see if you can spot Bicknell’s Thrush, a shy and reclusive bird known to reside (but rarely seen) on top of Slide Mountain. This is an excellent adventure for hikers looking for a gentler introduction to the Catskill tall peaks.

This is a required peak for Catskill 3500 Club Membership and #1 Catskill Tall Peak (elevation 4,184′). This is one of the four peaks that must be climbed twice, at least once in winter (December 21 – March 21).

What’s included:

Join us on a classic climb of the tallest mountain in the Northeast, with an extra challenge of doing it in precarious winter conditions. At 6,288 feet, boasting 4,000 feet of elevation gain over 4 miles, and harsh, unpredictable weather above treeline, this thrilling hike will challenge even experienced hikers.

Our adventure will take us up and down the classic Winter Lion’s Head Route, and we’ll experience everything from forest trails to the heart-pounding climbs up the steep, snow-covered slopes. Finally, we’ll make our way above the treeline and to the exposed summit cone.

If you are lucky enough to summit on a clear day,  you will enjoy gorgeous views of the White Mountains and be able to see as far as Maine, Massachusetts, New York, Vermont, Canada, and the Atlantic Ocean.

Experience: This trip is for experienced hikers with prior winter hiking experience. Please contact us at info@adventureuntamed.com for more information. We can help you create a training plan!

Accommodations: 4-person bunk rooms at the Joe Dodge Lodge, 2 nights.

Food: We will have lunch on the road the first day and the last day. Other than that, all meals are included.

Day 1

We’ll depart at 7:00 am, stopping for lunch on the road. After arriving at the Joe Dodge Lodge, we’ll go for a short warm-up hike. We’ll test out our gear and learn crampon and ice axe use, as well as the skills to stay warm, dry, and safe in unpredictable winter conditions. After a moderate scramble to the top, gorgeous views of Mt. Washington will open up right in front of us, and you can trace the route you’ll be taking to the summit the next day. That evening we’ll enjoy dinner, do a gear check, and get a good night’s sleep before the summit attempt the following morning.

Day 2

After a hearty breakfast, we’ll start the summit attempt of Mount Washington. The snowy terrain will get the blood pumping right away. Be prepared for steep ascents, especially as the day goes on and you enter the Alpine Zone and make your way up the summit cone. Once above the treeline, you may encounter extreme weather, but our guides will be there every step of the way to keep you safe. If the day is clear, winter-wonderland views of the White Mountains will open up at the top. The hike down, with its steep descents, can be just as challenging as the way up. Back at the lodge, we’ll unwind, relax, and have a delicious dinner to celebrate the day’s adventures.

Day 3

After a good night’s rest, we’ll pack up, eat breakfast, and relax for the leisurely drive back to New York City, stopping for lunch along the way. You have a choice to sleep in or go on an optional pre-breakfast hike!

In this hike series, we are taking on the longest hiking-only footpath in the world – one section at a time. This is a really cool section of the trail! We’ll take a short detour off the AT to check out the amazing views at Anthony’s Nose. We’ll then continue over the Bear Mountain Bridge and end at Bear Mountain State Park. Of course, this is the perfect opportunity to stop by the Bear Mountain Inn to get some hot chocolate after the hike. This hike is close to the City, so there is no long drive in the van to enjoy this adventure. Because this is a point-to-point hike, there is no need to double-back. It’s only the Appalachian Trail (plus Anthony’s Nose!), and it’s new places all day long. Come explore the AT with us!

Looking for a winter challenge? Hike the eastern half of the infamous Devil’s Path! Known as one of the most challenging hiking trails in the Northeast, the Devil’s Path has steep, rugged ascents and equally difficult descents, slowing down the pace of even the most experienced hikers. Conquering the eastern half will require you to scramble up rocky trails covered with snow and ice and navigate steep descents. We’ll have crampons, microspikes, or snowshoes, as needed, to set you up for success! You will have access to a resupply and bail-out point, and our guides will be on trail to help throughout the day. You will be able to tackle this trail at your own speed, provided you are with at least one other participant or guide. There will be a cut-off time 9 miles into the hike, to make sure no one is hiking in the dark.

If you are feeling up for a really intense day, join us to hike the full Devil’s Path in a day in the summer of 2025.

On this trip we will summit Indian Head, Twin, Sugarloaf and Plateau mountains. These are required peaks for Catskill 3500 Club Membership.

Note: Must have prior tall-peak hiking experience in the Catskill Mountains or Adirondack Mountains before joining. If you have questions, please don’t hesitate to reach out to info@adventureuntamed.com.

Join us on a sweet adventure! We’ll start with a beautiful hike through the winter wonderland of the Hudson Highlands. Then, we’ll make our way to the Hudson Highlands Nature Museum for a walk to the Sugar Bush Shack.

It’s going to be a syrupy good time!
