Spanish Harbor Wayside Park Boat Ramp is a paved single-lane ramp located at MM 34 on the bayside of US-1 in Big Pine Key, featuring concrete abutments and limited trailer parking (approximately 5 spaces).

The ramp is free to use and open 24 hours, though it has minimal amenities with no docks, fuel, bait, or restrooms available. Note that the parking lot is shared with a fishing pier, so spaces may be limited during peak usage times.
