Thank you @apsu! I walked for hours along the coast and it was all rocks and cliffs there. They have trails both by the ocean and up at the cliffs. Was pretty amazing! I didn't want to leave.
Oh the lens is nothing impressive, but it has served me well and I love it. It came with the kit. AF-P DX Nikkor 18-55mm 1:3.5-5.6G
