Welcome to

Lynn Woods Reservation is one of Eastern Massachusetts' best kept secrets.  At 2200 acres, it is the second largest municipally-owned park in the United States.  Located just 10 miles north of Downtown Boston, Lynn Woods is a recreational paradise, home to roughly 40 miles of rugged trails, flourishing wildlife, historical structures, pristine reservoirs, thousands of granite boulders/outcrops,unique geology, horseback riding, trail running,  and likely the best freeride mountain biking terrain in the Northeast!  Unlike the Middlesex Fells (a popular state-managed park also north of Boston), it is possible to hike, ride, or run in Lynn Woods without ever seeing another soul!  It is indeed easy to forget how close you are to the city when seeking adventures in Lynn Woods.

This site is dedicated to the amazing bouldering found at Lynn Woods.  Most New England rock climbers have only recently learned about the immense potential for this bouldering area, but already thousands of boulder problems have been established.  Much of the hype surrounding Lynn Woods was generated when the first version of our Lynn Woods North-Side Bouldering Map was posted online in February 2007.  Since then, interest in Lynn Woods has exploded and the park has slowly become a destination for climbers that would normally boulder at Lincoln Woods in Rhode Island or Pawtuckaway State Park in New Hampshire.  The size of the park is intimidating to first-time visitors though, and the prime boulders are well-hidden amongst the trees and rolling hills, so you will need a map and a boulder-sniffing sense of direction to quickly find the goods.  We've got you covered on the map end, but you're on your own as far as sense of direction goes.

The current Lynn Woods bouldering map is the most complete and accurate map available for the area north of Walden Pond (the main pond that sits roughly in the middle of the park).  Boulders, water bodies, terrain, and all trails are illustrated.  A map of the scarcer south-side bouldering and a mountain biking map showing the locations of big drops and downhill runs will be available soon.
