On Friday night, we made a last-minute decision to head to New York and tackle the final Catskill Fire Tower on our list. Saturday morning, after a long drive to the trailhead parking area, we didn’t start hiking until almost 11 a.m. I was surprised to see so few cars when we arrived, so I squeezed into a spot and we geared up. The temperature was pleasant, though the humidity was high, but manageable thanks to a light breeze.
Notably, this mountain is one of the few in the Catskills with several timber rattlesnake dens scattered around. These snakes are venomous, so it’s important to keep children close and dogs leashed.
The Catskill Fire Tower Challenge requires you to climb all eight Catskill fire towers between January 1st, 2026, and December 31st, 2026. Tremper Mountain is #7 on the Catskill Fire Tower Challenge and #17 on the Fire Tower Challenge (Adirondacks and Catskills).
The Phoenicia Trail begins just off Ulster County Route 40, with parking available for about 7–8 cars, depending on how they’re parked.
The Phoenicia Trail starts off with a pretty steep climb right after you cross the bridge, and about half a mile in, you’ll reach the old jeep road that leads up to the summit of Tremper Mountain.
The Phoenicia Trail has plenty of switchbacks and some steep, rocky stretches, but it never felt difficult to hike or tricky to navigate.
Along the Phoenicia Trail, there’s a pile of large rocks that looks like a slide but is actually an old bluestone quarry.
Another stretch of the Phoenicia Trail offered a pleasant and easy walk.
The Baldwin Memorial Lean-To sits at around 2,100 feet, with a privy nearby and a spring about an eighth of a mile up the trail. Not much water from the spring today, though.
A glimpse of the Tremper Mountain Fire Tower peeks through the trees. Standing 47 feet tall, it was built in 1917 and served until 1971, before being restored for public use in 2001.

The views from the fire tower cab on Tremper Mountain are stunning in every direction.
We didn’t spot any timber rattlesnakes during the entire hike, unfortunately. Overall, it was a pleasant trail that was neither too steep nor too flat. We eventually turned around and headed back to the car, passing a few hikers making their way up to the summit.
With the Catskill Fire Tower Challenge now complete, my favorite was probably Bramley Mountain or Hunter Mountain for their easy hikes and great views. My least favorite was definitely Overlook Mountain, which we tackled in winter under miserable conditions with far too many people. It was a nice change of pace from the White Mountains in New Hampshire and the Adirondacks in New York.
