Early prints of the venerable Claremont show an austere, four-story wooden building overlooking Somes Sound from a grassy rise. The tableau is the same, but as of a 2021 top-down renovation (undertaken by the hotelier behind the the Kennebunks’ Kennebunkport Resort Collection), the vibe is quite a bit flashier and a lot more luxe. The revamped Claremont has 38 guest rooms and suites in the historic main hotel, all done up in plush linens and piles of pillows and pastel, patterned wallpaper. New are a pair of elegant, tucked-away “signature houses” (if you have to ask, you can’t afford them) and 12 high-rustic cottages. The list of resort amenities is long and includes a spa, a heated outdoor pool with an ocean view, luxury cabanas strewn here and there for escaping the sun, a country-clubby game room, and new restaurants and bars, including the spendy farm-to-table option Little Fern and a chiller pub in an old boat house, with a designer fish-camp theme. The whole place has a chic new-money feel, but some of that old New England gentility remains: one of the country’s largest croquet tournaments is still held here each August.
