Sebastian, on Florida’s Treasure Coast, is a laid‑back coastal town centered on the Indian River Lagoon with great beaches, fishing, boating, kayaking and nearby nature preserves like Pelican Island and Sebastian Inlet State Park—perfect for a travel therapist who wants active outdoor time and a pleasant, never‑boring multi‑week stay.
Bigger options are a short drive: Vero Beach (~20 miles south) and Melbourne (~40–45 miles south) offer more dining, arts, shopping and medical resources while keeping Sebastian’s quieter pace.
