Frequently Asked Questions

Where is the trailhead and what are the parking options for this hike?

The trailhead for the Mount Paugus via Kelley Trail and Old Mast Road loop is located at the Ferncroft Trailhead. Parking is available there, but it's important to note that it can fill up quickly, especially on summer weekends. Arriving early is advisable to secure a spot.

Is this trail dog-friendly?

Yes, the entire trail is dog-friendly, making it a great option if you want to bring your canine companion along for the hike.

What is the best time of year to hike this trail?

The trail offers a rewarding experience in various seasons. However, spring can bring rotting snow and mud, so waterproof footwear is essential then. For the most pleasant conditions, late spring through fall is generally recommended. Always check current conditions before heading out.

Are there any permits or entrance fees required for hiking in the White Mountain National Forest?

While there isn't a specific permit required for hiking Mount Paugus itself, you are hiking within the White Mountain National Forest. A recreation pass, such as the America the Beautiful Pass or a local White Mountain National Forest pass, may be required for parking at some trailheads. It's always best to check the latest regulations for the White Mountain National Forest before your visit.

What is the terrain like on the Mount Paugus via Kelley Trail and Old Mast Road loop?

The terrain is varied and demanding. You'll encounter rocky sections, a dried-out streambed, and rock scrambling, particularly on steeper parts closer to the summit. The Kelley Trail has steep ascents as it nears the top, and can be slippery when wet. The final approach to the summit on the Lawrence Trail can be steep and rocky with loose 'kitty litter' rock. The Old Mast Road section can also have 'kitty litter' on the descent, though some find it more gradual and open.

How long does it typically take to complete the Mount Paugus via Kelley Trail and Old Mast Road hike?

This is a challenging hike. Based on typical hiking speeds, it generally takes around 5 hours and 50 minutes to complete the full loop. However, this can vary depending on your pace, breaks, and trail conditions.

What are the main viewpoints and natural features along the route?

The hike offers breathtaking views, especially from the ledges near the summit. You can enjoy expansive vistas of the Lakes Region and peaks like Whiteface and Passaconaway. Westward views reveal Potash Mountain and parts of the Franconia Range. A notable natural feature along the Kelley Trail is a stunning box canyon. The summit itself, Mount Paugus South Peak, provides an open, rocky area with panoramic views.

Is it better to hike this as a loop or an out-and-back?

While it's designed as a loop, some hikers prefer an out-and-back route using only the Kelley Trail. This is often due to the Old Mast Road section, which some find less pleasant for descending because of loose 'kitty litter' rock. However, others describe the Old Mast Road descent as very gradual and open. Consider your comfort with varied terrain when deciding.

Are there any historical or unique features to look out for on the trail?

Yes, the Kelley Trail passes through gorges carved by glacial meltwater, offering a glimpse into the area's geological history. The Old Mast Road also has historical significance, as it was used in the 1700s for timber transport by the Royal Navy.

Does this route connect with other trails?

Yes, the route incorporates sections of several official trails. You will hike along parts of the Kelley Trail and Old Mast Road, and also pass through sections of the Lawrence Trail and the Wonalacent Range Trail.

What should I consider bringing for this hike?

Given the challenging and varied terrain, sturdy hiking boots are essential, especially waterproof ones if hiking in spring. Bring plenty of water, snacks, and layers of clothing as conditions can change. Trekking poles can be helpful for the steep and rocky sections. Always carry a map and compass or a reliable GPS device, as well as basic first-aid supplies.
