Sarah Michelle Gellaris keeping the summer vibes going well into winter!

On Tuesday, the actress, 46, jokingly explained the reason why she’d been a bit off the radar over the holiday season. It seems she was enjoying a tropical getaway, where she wore a parade of stylish swimsuits.

“If I’ve left you unread…. Here is why. Vacation photo dump part one,” she captioned anInstagram postfeaturing a carousel of pictures documenting her fun in the sun.

She kicked off with a shot of herself in an orange belted tank-style swimsuit and a wide-brimmed hat. Another image captured her looking up into the camera, with her eyes hidden behind a pair of oversized black sunglasses. This time, she wore a ’60s-inspired floral-print two-piece suit.

In another photo, theBuffy the Vampire Slayeralum sported a different bikini featuring a ruffled top with a citrusy print of lemons and oranges. She also posed for an ocean-view snapshot at sunset in white denim cut-off shorts and a navy blue eyelet blouse with puffed sleeves. Gellar wore her hair styled in a sleek bun and accessorized with flower-shaped earrings.

Back in October, Gellar reminisced to PEOPLE aboutanother memorable vacationshe once took — although, this one was a bit more offbeat.

“When I was younger, I stayed in a haunted room at theHotel del Coronado," Gellar revealed, referring to the Coronado, Calif., beach resort that opened in 1888. “Years ago, you used to be able to ask for that room and stay in there.”

Despite the eerie ambience, Gellar’s stay turned out to be surprisingly uneventful. “Yeah. My weird experience was that I slept through the night. I slept great," she jokingly recalled.
