Trilha da Boa Vista is a mountain trail near Barra da Lagoa, crossing high ground toward Praia da Galheta. The reward is the view: ocean, beaches, and the green ridges of eastern Florianopolis spread out below the route.
Allow around two hours for the walk and bring water, sun protection, and shoes with grip. It is best treated as a scenic hike between beach areas, not as a casual paved promenade.
