Maybe the most popular trails in the entire park, pretty much all the main hiking trails are accessible from the 4 mile odd trail that surrounds the pond itself, however the views offered from the walk around the pond are spectacular. Shadowed by Cadillac Mountain behind which creates a great background (weather permitting) and the water is super clear making the pond bed visible at any depth. At the far side of the pond there is a small stony access to the pond which you can use to frame a shot. Unfortunate for me, the weather was less than perfect when I went but there are plenty of places online that will show you just what I mean.
The loop is a easy to moderate hike with some large rocks to navigate, so keep your kit in the back pack in those sections, if you’re a little unsteady on your feet. Much of the west-side has plank decking to walk across, which makes for some interesting sections.
Early morning or very late afternoon visits are best, midday will flatten the light and remove some of the chances of getting shadows and light beams through the trees at either end of the loop.
Look out for the “elephant tree” it’s quite the sight.
