The East Rock (4 Peaks) loop is a moderate hike that typically takes around 1 hour and 53 minutes to complete. This duration can vary based on your pace and how often you stop to enjoy the views.
The terrain on the East Rock (4 Peaks) loop is diverse, winding through woodlands, meadows, and rocky outcrops. You'll encounter uneven paths, small hills, and some steeper sections with rocks and roots. The park's trap rock ridge means durable dolerite, so expect a solid, sometimes challenging, surface. The summit of East Rock rises over 350 feet above the Mill River Valley.
This loop offers several fantastic viewpoints and landmarks. You'll pass by prominent summits like Snake Rock, Indian Head, and Whitney Peak. The highlight is undoubtedly East Rock itself, offering stunning panoramic views of the New Haven city skyline, New Haven Harbor, and Long Island Sound. Near the summit, you'll also see the historic Soldiers and Sailors Monument.
East Rock Park offers several parking areas. While the specific trailhead for a combined '4 Peaks loop' isn't officially marked, you can typically find parking near the base of the park or closer to the summit via the paved road. Check park signage upon arrival for the most current parking information.
Yes, East Rock Park is generally dog-friendly. However, dogs are typically required to be on a leash. Please ensure your furry companion is well-behaved and that you clean up after them to keep the park enjoyable for everyone.
The East Rock (4 Peaks) loop can be enjoyed year-round, but spring through fall offers the most vibrant scenery. Fall is particularly beautiful for foliage.

While the overall loop is rated as 'moderate', some sections can be challenging.

While there are no specific facilities directly on the trail itself, East Rock Park does have amenities.
