River Description

This is a nice but short pool and drop river. There are many 2 and 3 foot ledge drops amongst large granite boulders through a steep sided gorge. At low levels it can be a little scratchy at the begining and the end. There is not much playing to be had on this river section but it is a good place to learn skills for steep creaking. If the dam is spilling water put in at the first location by the dam. Walk down a steep embankment on river left downstream from the bridge. This will give you access to two warm up rapids (Upper and Lower White Pine rapid), with some surfing waves to play in. If the water is marginal or being bypassed by the hydro station it will be necessary to put in 1/4 mile further downstream.

Put in at the Campton Dam at the street light a the intersection of NH rte 49 and NH rte 175. The best spot to carry down is river left just downstream of the dam and rte 175 bridge. Note that during low water much of the water is diverted form the dam through a penstock under rte 175 and re-enters the river at a micro hydro station about 500 ft downstream of the dam. If clear laminer flow continues 1/3 of the way, or greater, down the face of the dam then there should be enough water for the first couple rapids (i.e. upper and Lower Big Pine). Anything less will be a scratchy run at best.

Big Pine (Class II, Mile 0.1)

Upper and lower Big Pine rapeds are straight forward easy drops.  At the lower levels, such as when the water is diverted around these rapids, they can be quit boney.  Rapid is named for a large tall white pine tree on river left.

Tavern Drop (Class III, Mile 0.3)

As soon as you turn right away from NH rte 175 the Mad enters the gorge section.  You will immediately start encountering several ledge drops spaced only a dozen or so yards apart.  One of the major ones is a couple drops downstream of an old metal discharge culvert at a cliff overhang on river left.  The drop is somewhat blinded by large boulders but the river right side has a clear path.  Drop is named for the Mad River Tavern which is on river right (out of sight) on top of the gorge on NH rte 49.

Sunset Drop (Class III, Mile 0.7)

Sunset Ledge

Nice 3 foot ledge drop great for learning boofing manuevers.  Left side is more vertical and has a fairly mean hole in it at higher levels. Feature is named after Sunset Hill on river right above the gorge.

Take Out

As the river slows down to a few ripples look for an easy exit over the loose gravel and boulders on the river right bank.  The takeout from the road is located behind A&H Aoutomotive.  From exit 28 turn right on the road between A&H and the Handyman Hardware store.  Just past the harware store take a left at the Embroidery factory and park in the roadside clearings by the factory.  You should take a walk into the woods to the river to try and get visual marker so you can recognize the takeout from riverside.
