Aspen Ridge-Boulder Ridge - 6.2mi Moderate Loop

Q: Can I hike this alone safely?

Yes, but tell someone your plan and expected return time. Cell service is unreliable. The trail is well-marked and moderately busy—you'll see other hikers. Avoid solo trips in bad weather or at dusk.

Q: Do I need special gear or poles?

Trekking poles reduce knee strain on the descent and help with boulder scrambling. Waterproof boots are smart (creek crossings exist). A map is wise backup. No ropes or climbing gear needed.

Q: How much water should I carry?

Minimum 2 liters. The boulder field is sun-exposed with zero shade. In summer heat, 3 liters is safer. Phelps Lake water is drinkable if filtered, but rely on carried water for the hike out.

Q: What if I get to the parking lot and it's full?

The lot fills by 7–8 AM mid-summer. Arrive by 6 AM. If it's full, wait 1–2 hours or hit Hermitage Point Loop (same preserve, quieter). Check NPS.gov for real-time lot status if available.

Q: Are there bears on this trail?

Yes. Black bears use this area, especially berry season (late summer). Make noise—talk or use a bear bell. Never run if you see one; back away slowly. Carry bear spray if comfortable using it.

Overview

About This Trail

This moderate loop through Laurance S. Rockefeller Preserve tests grit with relentless elevation gain and a boulder field demanding scrambling skill. You'll traverse aspen groves and navigate technical rock work before earning the payoff—Phelps Lake's shore with Death Canyon views. Expect to push 1,140 feet uphill over 6.2 miles with zero mercy from exposure. Not a stroll; this is where hikers discover what they're made of.

Highlights

Difficulty Level

Moderate—Technical boulder sections and 1,140ft gain demand fitness and scrambling comfort.

Trail Highlights

Loop hike to scenic Phelps Lake with Death Canyon vistas. Boulder scrambling adds technical challenge and aerobic demand. Moderate elevation gain with mixed shade through forest and open rock.

Insider Tips

• Phelps Lake's reflection shot is best at dawn (6–7 AM) when light is soft and fewer hikers present. • The boulder field is the crux—don't rush it; set a conservative pace through the scramble. • Stream crossings manageable mid-summer but swollen in early June; expect wet boots in spring. • Going in September? Start early before fall foliage draws crowds.

Best Season to Hike

Spring (May–June), Summer (July–August), Fall (September–October).

Hiking Tips

Carry 2+ liters of water—the boulder field has zero shade.
Tighten boot laces before entering the rock section—loose boots cause ankle rolls.
Make noise if you see wildlife (bears, moose).
The trail crosses creeks; wear waterproof boots or expect wet feet.
Leave by 2 PM to descend in daylight.
Trekking poles reduce joint impact on the descent.

Family Info

Suitable for kids 12+ with hiking experience. Boulder scrambling requires surefootedness and confidence on uneven terrain. Younger children may struggle with technical sections and elevation gain. Keep children close in exposed boulder areas.
