Mount Avalon is a 3,442-foot mountain in New Hampshire’s White Mountains, located in Grafton County as a small rocky spur of Mount Field overlooking Crawford Notch. Its summit is reached by a side path from the Mount Avalon Trail, which continues higher toward Mount Field. The mountain’s slopes drain into Crawford Brook, whose waters flow north from Crawford Notch to the Ammonoosuc River as part of the broader Connecticut River watershed.
