Summer art means adventure for me and my siblings. It meant early evening drives on unfamiliar New England roads — in a 1970s Volkswagen minibus, no less — as our theater professor father sought out a different summer stock theater near our weekly rental home. It was an annual quest, and one that introduced us to musicals, farces and whodunits.

The titles of the shows have faded, but not the sense of adventure that entailed finding our way — pre-GPS — to a new small town and its converted barn or refurbished theater. These outings were not all artistically satisfying, as exemplified by the show we remember as “Headless Mame” because we couldn’t see the face of the star whenever she moved downstage. But great art wasn’t the point. These evenings linked theater with vacations and family time.

Your summer artistic ad­ven­ture, whether theater or indoor art exhibit, doesn’t have to take you far. Just channel the season’s casual vibe as you gather family and friends. Take a risk on the unfamiliar. Discovery awaits.

You never need a reason to venture out to the Kreeger Museum, a treasure in the Foxhall section of the city, but a new piece in the newly opened woods behind the museum is a lovely excuse. An extension of its sculpture garden, the five-and-a-half-acre woods and its meandering paths offer a shady oasis that will be especially pleasant when temperatures rise.

Its site-specific installation, “Portals” by Sandra Muss, features seven 10-foot-high steel-and-glass columns that reflect and engage with their natural environment. Arranged in a mazelike configuration, the columns are wrapped in wire and vines that mimic and reflect nature.

The woods are a place of peace, Muss said about her inspiration for the work, a gift to the museum.

“The woods are an opening, a way into myself and out of myself,” she said. “I hope others open that door, that portal.”

Muss’s work invites guests to wander into the woods from the sunny lawn, where Kendall Buster’s “Garden Snare” and Ledelle Moe’s “Transitions/Displacements” are on view. The forest paths lead to the museum’s plaza and reflecting pool on the other side of the museum.
