Saba is known for pristine diving. The reef surrounding the island is a nature preserve and very well kept. The pinnacle dives, although deep and therefore shortening the length of the dive, were spectacular.
Sadly, I didn't do much hiking, but I did make it out to some of the outlooks. After three dives a day, I didn't want to chance overexertion and climb to the top (also a park), but I hear it is spectacular.${QuickSuggestions} Saba has a 3% tax you can avoid by paying for your vacation in advance by check. If you pay once on the island or by credit card, you are taxed.
Sea Saba is a great dive shop that assists with any needs you may have, not just diving. We were there over Easter, and they called around the island to find the holiday service schedules at all the churches.
Sea Saba also booked dinner reservations on our way down to the boat each day. You may find it strange, that with so few people it is necessary to have reservations, but to keep costs reasonable, many restaurants only prepare enough for those that signed up. Also, the restaurants are small, so it is best to check out the daily specials and plan ahead each morning. ${BestWay} Saba is a lot of "uphill". We preferred the experienced taxi rides arranged by the dive shops to escort us around the curvy roads, but once back on the windward side, everything was a short walk away (usually uphill).
If you book a package through Sea Saba, they include the trips to and from the airport, as well as to the boat. We were often dropped off at the shops after a day of diving so we could walk DOWNHILL to get back home.
They said a road could not be built. Engineers came to the island and declared it impossible. Mr. Haskill, a local, disagreed. He took a correspondence course in engineering and built the road that snakes around the island today.
