HUMISTON PARK
On Ocean Drive just 300 yards south of Rt60 / Beachland Blvd. An Oceanfront park offering a large grassy picnic area with playground equipment, covered  tables, showers, boardwalk and life-guarded beach.
Surfing is not allowed , but just South of the Park there is a large strip of unguarded area, the break is not that good, because the bottom is moderately deep in close and the reef acts as a wave block, but it is popular with the Skim Boarders.
Divers love this area, it has reef within a stones throw with 10 to 20 ft depths, You can swim over 4 different Reef  sections, This is also the location of the Brechnshire Wreck an old steam ship that crashed on the 4th reef and got stuck between the 3rd and 4th reefs, depths are 20 ft. and the boiler is visible on a calm day, it is a good long swim out to the 3rd and 4 reefs, approximately 100 yards out.  do not dive this area if there is any wave action, the reefs are big with large open cave like holes that one could get pushed up against in a strong surge.  Visibility  along the  Treasure Coast Sebastian to Stuart  is very dependent on the weather, requiring calm seas for at least a day,  usually by the 2nd day of calmness the visibility is usually 6 to 20 ft. depending on the depths and bottom conditions.  Lots of Fish and Lobster, plus Turtles and Nurse Sharks.  Note: Just  Next door to Humiston is one of the best Hotel resorts around, it is called the Drift Wood Inn and it literally is made of Drift wood,  it is also right off the Reefs mentioned above.
