Deep Sea Adventure offers an immersive journey through maritime history and ocean exploration at Weymouth’s Custom House Quay. This family attraction features dramatic walk-through experiences including a Victorian diving bell descent, underwater treasure hunting adventures, and exhibits on shipwrecks and maritime archaeology.

Sharky’s Play Zone provides energetic indoor fun for younger children with climbing frames, slides, and soft play areas themed around ocean adventures. The combination of educational exhibits and active play makes this an ideal family destination, especially on rainy days. Located on the picturesque harbour, it’s perfect for combining with harbour walks and boat trips.
