There is a small parking area at the put-in near Ayers Island dam. There is a porta poty located here along with trash cans. Additional parking can be found at the top of the dam where a hiking trail leads down to the put-in parking lot.
The river is about 1-1/2 miles long with three distinct play spots. The first big drop is about 1/4 mile downstream with a medium size sidesurfing hole (Rodeo Hole)it is not for novices to play in. Run right at this point. Downstream 100 yards there is a good surfing wave depending on level. The river from this point to the take out is mostly small rapids with a few oppertunities for surfing a sidesurfing. The last rapid is a series of reactionary waves and holes caused by protruding ledges on a long sweeping right turn. The last ledge at the take out is probably one of the best summer time play spots in NH with a great sunning and spectating rock to go with it. Depending on level it is either a sidesurfing hole, surfing wave, and or ender spot.
You can takeout at the Pemi Park & Play or just slightly downstream at a ledge. This take-out is easier for canoes and rafts. It also leads up to a small parking area on Coolidge Woods road which has new porta poties maintained by Public Service company of NH.

Interstate 93 north to exit 23.
Left on state rt. 104 (west) towards Bristol.
Approximately 4.5 miles, look for a baseball field on the left.
There will be a yellow playground sign just before you get there.
Take a left here and go around the ball field towards the recycling
Drive past the entrance to the town garage, sewage treatment
facility, and recycling center. The road at this point turns to a
rough dirt road descending steeply to the small parking area at the
base of the dam. Note new handicap accessible outhouse.
Directions to the take out:
As of the Fall of 2009 a new bridge opened to replace the metal truss bridge that used to cross the river from Bristol to New Hampton. This cuts the shuttle down to 2 miles from the 8 miles we had to endure over the last couple years.
Head back out to NH rt 104 and take a left toward Bristol.
In the center of town at the intersection of rt 3a take a left then another immediate left in the town square.
Take the right (downhill) at the fork.
Follow the road down over the bridge then take a right on Coolidge Woods road (dirt).
Approximately 1/3 mile to take out. Look for
vehicles parked at the
play spot. Or take out a little further down stream where the river
In the summer of 2006 a new river access path was put in by PSNH. It is accessed from the same
parking area. The path leads a short distance downstream from the old put in. The path is made up
of crushed stone and has an even grade all the way to river level. This is a great improvement
over the continually shifting rock jumble we used to put in at.
In 2003 Public Service Company of New Hampshire installed an artificial osprey nest at their
Ayers Island hydro facility. Since that time a nesting pair of Ospreys have taken up residents to
raise their chicks for the last few years. This Nest is visable from the putin. Look to the river
left side of the dam to view the telephone pole platform with a large nest on top. In the summer
of 2006 PSNH installed a webcam so we can
view the nest at anytime.

The first big drop is about 1/4 mile downstream with a medium size sidesurfing hole (Rodeo Hole)it is not for novices to play in. Run right at this point. After the first few small class I-II rapids from the put-in, the river widens and slows down. You will notice a ledge protruding from the left bank (Wourthen's Rock) forcing the river to the right. Get out and scout on these ledges or run to the far right to avoid "Rodeo Hole". The rapid continues for about 1/5 of a mile with waves and turbulance and a few rocks to avoid. Just downstream from the middle of the rapid you will notice the river takes a slight jog to the left between another set of ledges, eddy out river left below the ledges to catch a nice surfing wave.
Nice sidesurfing hole located at the very top of Bruning's. Approach the top of Bruning's at the horizon line about river center. The hole turns into a surfing wave just right of river center. There is no convienient eddy to hop in and out of the hole so it will be necessary to catch it on the fly then return by carrying back over the ledges from the river left eddy just slightly downstream. The hole is best at about 1300 cfs, below this level down to 800 cfs the hole gets stickier and shallower so watch your head should you flip upstream. There is also a nice surfing wave that can be accessed from an eddy just downstream. It is best at 800 cfs to 1500 cfs.
The last rapid is a series of reactionary waves and holes caused by protruding ledges on a long sweeping right turn. The last ledge at the take out is probably one of the best summer time play spots in NH with a great sunning and spectating rock to go with it.
