The Magalloway River offers what they call Class 3 and Class 4 rapids, depending on the time of year. The river is one of several used by RaftNH.com, based out of Gorham, NH for white water rafting. Their rafting trips are operated daily May through September. Reservations are required. The ride down the river takes about 34-45 minutes. Each of the rubber rafts takes 7 people and a guide. We took this ride in late August, 2011. It was one of the first times we’d used a GoPro HD. We also had two Canon DSLRs on the river bank. The GoPro shoots in highly compressed mp4 format. It was necessary to transcode its video into Pro Res 422 and color correct the video.
