Accessible through your mobile device or your computer. Use AllTrails to find local hiking, cycling, and walking trails. Since the information here is crowd-sourced, I recommend verifying routes using paper maps or apps like GaiaGPS.

Use GPS software to map out hiking, cycling, and walking routes. Note: this app can be used offline, but you should still have a paper map.

Most trails here are easy to moderate, except for the blue and white trails, which are difficult. Whether you're looking for a challenging rock scramble or a pleasant nature walk, Sleeping Giant has it all. Tip: this is popular hike in an urban area, so get there early, at least on weekends. Also, if you like a challenge, look up the Giant Master Program.

One difficult section, otherwise moderate. 6.8 miles, mostly on a ridge, with good views to the west and one killer (seriously) rock scramble. Note: cell service is pretty spotty in this area.

Mostly moderate. This 5-mile loop takes you over two summits and through three states (you'll see the tri-state marker), as well as the official Connecticut state highpoint. Beautiful views from the ridge and from Brace Mountain.

Moderate as an out-and-back. If you make it a loop, the north side has one steep climb (not recommended in wet or icy weather.) The highest mountain in Connecticut, though not the state highpoint. Great views from the summit, and it connects with the Appalachian Trail. Tip: if you do the loop, go counterclockwise to avoid descending the steep north side. Also, this is a very popular hike, so get there early (lot is usually full by 9:30 on weekends).

Moderate. This hike follows the Appalachian Trail over Mount Prospect and through an unexpected and strikingly pretty field (Rand's View), with excellent views to the north. Raccoon Hill is optional, but Giant's Thumb is interesting.

Easy (but a little rocky in places). This loop hike is under 3 miles and affords fantastic views that make you feel much farther away from New Haven than you actually are! Tips: Since there are views to the east and west from the top of the ridge, this is a great hike for sunset, sunrise, and moonrise. Because of the cliffs, this hike may not be good for those with a strong fear of heights.

Moderate. Lovely views and interesting rock formations await on this popular hike. Part of this hike follows the blue-blazed Metacomet Trail, which is a section of the New England Scenic Trail, which runs from the Long Island Sound to the Massachusetts/New Hampshire border. Tip: parking is limited, so arrive early, especially on weekends.

Moderate-to-challenging. If you like scrambling over interesting rock formations, this hike is for you. Part of this trail skirts a pond, which is good for wildlife viewing. Tip: Because of the rocks, it's best to avoid this trail during wet conditions.
