First of all:
Rent a car. Even if you only stay in Las Palmas it's the best way to get around.
Spots: Think all of it is shown in the insta channel. Still, Las Palmas has a lot to offer, but there are hidden spots all over the island. Most spectacular is the fullpipe in the hills. Maspalomas has an amazing Plaza on the hill and some other stuff.
You'll find a great Hubba spot here, that's worth at the end of a session: C. Obispo Vela, 30, 35110 Santa Lucía de Tirajana, Las Palmas, Spanien
Went there twice and always had a blast.
