>>2701923as far as northern new england goes, the mountains tend to be smaller but more technical cuz we basically go straight up then straight down. it's fairly common for ascents to require some bouldering and descents to have steep, smooth rock walls. also, i've never had a problem with dispersed camping in various public lands. it's worth checking before you go, but there's plenty of developed and undeveloped land where they're cool with it as long as you're not shitting in the water and breaking glass
also, a lil protip: forget about mountains and seek out beach forests if ya can. picrel is from kejimkujik seaside in nova scotia, which has a little bit of everything. you start out in a dense, lichen-heavy forest, then go to a scrubby open field dotted with boulders, then to an ancient beach where the sand is still rocks, then to a transitional forest (sandy floor), then to a mossy swampy forest (picrel), then to a traditional sand beach, then to a massive rock formation with tide pools and crashing waves
i know that PNW also has beach forests, but something about maine and even massachusetts' complex coastal ecology just gets me rock hard
