If you enjoyed Paros and Antiparos you will enjoy Naxos.
I also love Antiparos ... if you are short on time, and only have 2 days, Antiparos can be enjoyed in that time, as it is so much smaller than Naxos == the ideal solution of course, is to see both. Antiparos does tend to "close down" a bit earlier than Naxos, because the latter has a large year-round population (very diverse economy, with farming, vineyards, small mfg, crafts, aside from tourism) ... other indications of permanency (thriving school system, good hospital, town councils…
June is much less crowded in June than in July or August, not to mention nowhere near as hot, so either go then or in early September. The best options for summer travel with small kids would be the secondary islands that don't get quite as much tourist traffic because of their worldwide popularity. I recommend Antiparos. It's easy to get to from Paros, which has an airport as well as the ferry. From Paros it's a quick and easy shuttle ferry ride to Antiparos. If you fly to Paros you can…
Going to Albania for a week or so. Going to be active enough, sightseeing via local buses with some beach downtime on the coast. We have 5-6 days when we'd like to go to Paxos and AntiPaxos to chill out, do some low impact, shallow water, easy snorkelling, drink beer at beach bars, eat local grub, avoid tourist hotspots. Planning to take ferry from Sarandë....
- What are good beaches to do the above...?
- Can we take one ferry (with stops) from Sarandë to Paxos in one go......?
- Any particular…
Naxos, or Paros and Antiparos are close and would round out your experience nicely. I'd go with Paros and rent a scooter to take over to Antiparos on the frequent little car ferry from the secondary port of Pounta and go up the mountain to see the cavern. It's very interesting and traffic is very light all over the island. Then you can stop at Apandima Beach for a swim before returning to Antiparos Village for lunch. Scooters make exploring both islands a lot more fun and traffic on Paros…
I think Antiparos would be a good fit. Check it out: http://tinyurl.com/zt86adv
Paros, Ios and Mykonos are great options for party. Santorini is very romantic and Naxos has great beaches and is famous for its relaxed and family atmosphere. As for backpacking and camping style vacation, a lot of backpackers chose Amorgos, Antiparos, Anafi and Astypalaia. You will meet there a lot of young people who like relaxed and alternative vacations.
They're very similar. For me the advantage to Paros is the easy access it provides to Antiparos by local and frequent shuttle ferry, as well as a shorter excursion boatride in the open sea to Delos and Mykonos Town than if you were to depart from Naxos. Paros is also a shorter distance to Athens.
Antiparos is a charming small island with a friendly village "feel" and a couple of child-friendly beaches within easy walking distance to the village center. You get there from nearby Paros, and Paros is accessible on a daily basis by plane or ferry from Athens and several other nearby islands including Naxos, Santorini, Ios and Mykonos.
Since you'll already be on Paros, why not go to Antiparos as well? It's easily reached by frequent daily local shuttle ferries from either the main village of Parikia or the westernmost port of Pounta. From Pounta it only takes 15 minutes to reach Antiparos.
