Too early for whale watching. Fishing will be limited. Maybe some roosterfish from shore, or if you rent a kayak you can catch snapper (good eating) and tons of triggerfish (toxic). Use small spoons.
Youre in Napolo, which is about 9 miles from town. I'd rent a car. Stock up on food at one of the grocery stores in loreto. I prefer Ley's. There's a little sundry store in Napolo, but that's about it. Cheap beer there.
The golf course is pretty good. (My brother's house is by the 11th green, so I'm pretty familiar with it). Front nine is nothing special but the back 9 is pretty spectacular. Decent fishing near the estuary by the bridge, and also near the rocks and around the corner from the beach.
Massage at the hotel is pretty good and reasonably priced. Breakfast buffet is pretty lame and the coffee is awful. Bar by the pool serves a decent lunch and stiff drinks.
In founder's village there's a wine bar with good sangria. They will give it to you to go if you ask. The coffee shop is ok.
Best restaurants in Loreto are Mita Gourmet and 1697. Get chocolate clams as an appetizer no matter what.
For casual go to asadero super burro. Great burritos.
theres a place closer to the airport out in the brush off the side of the road called Sabor. Good barbecue.
"sports bar" means strip club. There are 3. Rodeo is the best. Strippers start around 10:30-11. Beers there are about $2, a lap dance will run you $5 (same as a shot of tequila). Strippers will offer to have sex for an hour at varying rates. Everything is negotiable and I don't really know why you'd want an hour.
There are pool tables in the other room.
Glass bottom boat tour is pretty good.
let me know if you have specific questions. Loreto isn't Cabo. It's slow and full of expats. Because of that, stuff closes and reopens whenever the owners leave. Some things I listed may be closed or dead.
