Parking for the preserve is available at a commuter lot. From there, you'll have a short walk along Four Mile River Road to reach the entrance, which is located across from the Transfer Station.

How challenging are the Upper Three Mile River Preserve trails?

The trails offer varied difficulty. While the komoot tour for the combined White, Red, and Green Trails is rated easy, the preserve itself is known for moderate to challenging sections. The White Trail, in particular, features steep areas and stream crossings, making it more suitable for experienced hikers. The Green Trail offers a shorter and generally easier option.

What kind of scenery and terrain can I expect on these trails?

You'll hike through a diverse landscape featuring high, craggy ledges and broad hilltops. The preserve showcases a 'forgotten landscape' of abandoned farmland and woodlots, with an abundance of mountain laurel. Seasonal brooks wind through the area, especially prominent in late winter and spring.

When is the best time of year to hike the Upper Three Mile River Preserve?

Late winter and spring can be particularly scenic with rushing stream crossings. However, the preserve offers beauty year-round, with mountain laurel blooming in spring and varied foliage in autumn. Be prepared for potentially wet conditions during wetter seasons.

Are dogs allowed on the trails at Upper Three Mile River Preserve?

The provided information does not specify a dog policy. It's always best to check the official Old Lyme Land Trust website or local signage for current regulations regarding dogs, including leash requirements.

Are the Upper Three Mile River Preserve trails suitable for families or beginners?

What are the White, Red, and Green Trails like?

The preserve features distinct White, Red, and Green Trails. The White Trail is noted for being moderate to challenging, with steep sections and stream crossings.
