One is the recommendation (noun), the other is to recommend (verb).
Noun. A recommendation or suggestion meant to help someone make a decision.
His advice saved me a lot of trouble.
Su consejo me evitó muchos problemas.
Can I give you some advice?
¿Puedo darte un consejo?
She gave me good advice about investing.
Ella me dio buenos consejos sobre inversiones.
Verb. The act of giving recommendations or guidance to someone.
I would advise you to see a doctor.
Te aconsejaría que vieras a un médico.
She advised her students to review their notes.
Ella aconsejó a sus estudiantes que repasaran sus apuntes.

Aconsejamos a todos los pasajeros llegar temprano.
Common mistake
Trying to conjugate 'advice' as a verb. Wrong: "She adviced me." (correct: She advised me.)
Trick to remember it
Listen to the ending: 'advice' ends in an /s/ sound (like 'nice'). 'Advise' ends in a /z/ sound (like 'rise'). Noun ends in /s/, verb ends in /z/.
Quick rule
Need the recommendation (noun, what someone gave you)? Use 'advice'. Need the action of recommending (verb)? Use 'advise'.
Did you know?
This noun/verb pattern with different pronunciations repeats in English: 'device' (noun) / 'devise' (verb), and in British English 'licence' (noun) / 'license' (verb). The '-ice' ending almost always signals a noun.
