The San Martin put-in is the best option for trips that are doing an overnight on the Pacuare. It adds just over 4 kilometers to the standard one day run, which is necessary as most of the lodges and camps are in the first half of the run.
Like all Pacuare River put-ins, San Martin is privately owned, and prior authorization is necessary as there is a gate on the road. To get this access, please email Pacuare Outdoor Center and they will get it sorted out for you. Please note, this road does require four wheel drive. If your vehicle is questionable, or you are looking for a faster option to get on the water, then using the Linda Vista put-in is a better option.
