Get away from the beach and head home. It's a lost cause

(chapter originally by rojoa at writing.com)

It's time to head home. Isabel seeks the quickest escape she can find. The route she took to the beach was leisurely and took her past several beach shops and a pier populated with tourists, all of whom she's eager to avoid.

The quick route is arduous: a steep but walkable trail up an eroded cliff with a well-worn trail lined by the occasional sparse bush. She's done it before without trouble. With a bit of a running start she knows she'll get up there quickly and discreetly and then home.

Despite her flipflops, Isabel is able to get a good running start. Before she knows it she's halfway up the hill. A few steps later she feels her foot shoot back as it dislodges a chunk of sandstone. She looks back and is surprised to see a flipflop sliding down the hill. Then she realizes too late that her hands are holding onto branches rather than her towel.

A moment later her towel slides down the hill and catching a breeze fills up like a sail and drifts towards the ocean. She watches in horror as it's lifted up over the beach then over the surf. It continues, in the air, to sail over the waves before drifting down towards the water, where she loses sight of it. In frustration she flings her remaining flip flop towards the ocean.

Isabel is wearing only bikini bottoms and clinging to the side of the trail. What should she do next?
