July conditions?

So we plan on coming for a vacation in July. How are the conditions? Is it really crowded at La Ropa? What is the best way to get from airport and return? I'm really looking forward to it. Thank you for any input and extra tips for a family of six, grown kids. We are quite adventerous but know we have to be mindful and careful. We basically want to hang at the beach, snorkel, fish, go to some restaurants. We like hiking and natural areas but not sure that would be possible. We went to Loreto last summer and loved it. On my bucket list since 5 years old has been seeing the monarch butterflies, but not getting hopes up on that.
