Snorkeling, diving and boogie boarding are very popular here.  One of the best spots to snorkel is "The Aquarium" at Playa Mora, located over the hill west of the palapa restaurants.  Hike up the hills at Punta Herman's (brothers point).  From here you can see La Manzanilla across Bahía Tenacatita and wide vistas out to sea.  Watch the surf pound the coarse ankle deep chocolate sand at Playa Boca, just over the isthmus from Playa Mora.  Sunsets from this vantage point are spectacular.  You may decide to Rent a "panga" behind the village for a tour of the mangrove marsh or try sports fishing on the bay with a beachside panga guide.  Many just relax under the shade of a palapa savoring a few cervesas and enjoy the ocean view.

There is no local bus service to Tenacatita, but taxis will take you here from Barra/Melaque for about $400+p.  Backpackers can take a regional bus to the junction for $20+p, then hitch a ride to the beach.  There's lots of local traffic to pick you up.  The 9 km is too far to walk comfortably in the heat of the day.  If you hitch in, don't stay too late, as most people leave around sunset.
