Kayak Napoli

Great experience with Kayak Napoli. It’s a little ways outside the center of town, but that’s better, because then you get to paddle around less-​developed areas. The bus ride out there (#140) took about 30 minutes. From the bus stop opposite Teatro Posilippo, you walk up the road another block and then turn right (away from the water) down a sloping driveway that loops back under the road and down to a resort/​restaurant.
Kayak Napoli has a deal with this resort that allows the kayakers to use the pool, showers, and bathrooms for free — which gives you a place to hang out and relax before and after paddling — but the actual launch site is down at the base of the cliff in a little cove. It’s as quaint and beautiful as you would want.
I did the 1:00pm tour (3 hours long) on a Friday afternoon in July. There were 7 other people who showed up at the same time. You have a choice of solo or tandem kayaks. Most of the kayaks are sit-​on-​top style, but they have some traditional cockpit style boats as well.
Our trip route took us along the coast to the west, paddling near (and through) several ancient Roman ruins that are now partially submerged in the water. We had a few opportunities to hop off the boats and snorkel around in protected coves. The trip also included paddling back a short distance into a few natural caves along the coastline.
The guides and staff were incredibly friendly and knowledgable, and everything was geared toward a truly relaxed good time.
