Though just a small island, Talikud is very popular as a scuba diving destination. Two of which sites are Mansud Wall and Coral Gardens. There are also several small resorts lining the exterior, including Isla Reta and Bali Hai.
Talikud Island has a wide variety of soft and hard coral gardens that are home to numerous exotic small tropical fishes. Not only small tropical fish, larger marine life can also be found in here like barracuda, tuna and jacks.

Boats for Talikud leave every morning at 6am, 7am and 9am (P50) from Santa Ana wharf in Davao. While it only takes a ten-minute boat ride to get to Samal Island, the trip to Talikud Island takes around 30-45 minutes, but it is well worth the trip.
